The Omega Globemaster is the brand’s only watch that carries full Master Chronometer certification, a fluted tungsten carbide bezel and a pie-pan dial — but at $7,900 for the entry steel model, it needs to compete with the Rolex Datejust on feel as much as on paper.
When Omega launched the Globemaster in 2015 it was making a statement: this is what a modern, technically serious dress watch looks like when you build the movement first and the marketing second. Eleven years on, the formula is unchanged. The 39mm steel Globemaster — reference 130.33.39.21.03.001 in blue, or 130.33.39.21.02.001 in silver — is still the one most buyers consider, and it still divides opinion between people who find it quietly distinguished and people who find it a little busy. This review covers that watch in depth, with a section on the 41mm Annual Calendar variant for anyone stepping up to a complication.
I have examined multiple examples of the 39mm steel Globemaster — blue dial and silver dial — alongside the 41mm Annual Calendar. What follows is an honest account of what this watch does well, where it falls short, and whether the $7,900 asking price is justified in a market that includes the Rolex Datejust 36 and the Omega Constellation.

TL;DR — Omega Globemaster: Best-in-Class Movement, Divisive Design
The Omega Globemaster 39mm in stainless steel (ref. 130.33.39.21.03.001 or .02.001) retails at $7,900 on leather and $8,300 on bracelet — or roughly $5,000–$5,500 on the grey market. The Cal. 8900 Master Chronometer is one of the most technically accomplished movements at this price, with COSC and METAS dual certification, 60 hours of power reserve and anti-magnetic resistance to 15,000 gauss. The case is 39mm wide and 12.6mm thick — an ideal size for dressier occasions. The one reason to hesitate: the pie-pan dial and fluted bezel are an acquired taste. Who it suits: buyers who want Omega’s finest movement in a formal package and appreciate vintage Constellation styling. Who should look elsewhere: buyers who find the dial fussy, or who want a sports-dress watch with a bracelet as the primary wear option (the bracelet exists, but the watch looks best on leather).
What is the Omega Globemaster?
The Globemaster sits within Omega’s Constellation family — the dressier, history-rich counterpart to the Seamaster and Speedmaster — but it occupies the top of that family in technical terms. The name itself revives a late-1950s Constellation designation that was used on certain American-market models featuring the distinctive pie-pan dial, a softly cambered surface with radiant finishing and applied markers that creates strong depth and legibility. Omega relaunched the Globemaster name in 2015 specifically to house its new Master Chronometer certification, making it the world’s first METAS-certified production watch.
There are two sizes in the current catalogue: the 39mm three-hand date, powered by Cal. 8900 or 8901, and the 41mm Annual Calendar, powered by Cal. 8922 or 8923. Both share the same family DNA — fluted bezel, pie-pan dial, observatory caseback medallion — but the 41mm adds a centre-mounted month hand and text around the dial perimeter to display the current month. The 39mm is available in steel, two-tone, yellow gold, Sedna gold and platinum. The 41mm adds tungsten carbide bezel treatment on steel models. This review focuses on the 39mm steel, which is the volume seller and the watch most buyers research.
Design, Dial and Case
The case shape on the Globemaster is a reinterpretation of the C-shape form associated with Gerald Genta’s Constellation work from the 1960s. At 39mm wide and 12.6mm thick, with a 46.7mm lug-to-lug measurement, it is genuinely compact by modern standards — the kind of watch that disappears beneath a shirt cuff in a way that a 41mm or 42mm case simply cannot. The lug width is 20mm, which means an enormous range of aftermarket straps will fit. The case has chamfered, polished edges with brushed flanks, a combination that catches light without looking flashy.
The bezel is the defining external feature: on the steel model, it is made from tungsten carbide, an extremely hard alloy that resists scratching far better than conventional stainless steel. The fluted texture gives it a formal, faceted look that directly invokes vintage Rolex Datejust references — this is intentional, and is either appealing or unsettling depending on your view of Omega borrowing design vocabulary from its principal competitor. The steel Globemaster uses a polished tungsten bezel; two-tone and precious-metal versions use Sedna or yellow gold fluting.
The dial is polarising. The pie-pan construction — a lightly raised outer chapter ring with a lower central surface — creates a three-dimensional quality in hand that photographs rarely capture. The sunburst-finished blue dial (the .03.001 reference) is the more popular choice; the silver-white (.02.001) reads as more traditionally dressy. Applied hour markers and hands use a polished finish that picks up ambient light beautifully. The constellation star at 6 o’clock is a signature detail from the Constellation family. For buyers who find the dial busy: there is no subdial, no tachymetre, no colour accent — the complexity comes purely from the surface treatment, and in person it reads as deliberate rather than cluttered.
The caseback is a show-stopper. Through the domed sapphire exhibition window, the observatory medallion — a traditional Constellation element referencing Omega’s chronometer trials — frames the movement beautifully. The eight rotor stars reference the eight METAS certification tests. The crystal is domed sapphire with anti-reflective coating on both sides. Water resistance is 100m. There is no screw-down crown, which is a deliberate choice for a dress watch that prioritises ease of setting over the extra resistance a screw-down would add.
Movement: Calibre 8900 Master Chronometer
The Calibre 8900 is, without qualification, one of the most technically accomplished movements available at or near this price point. It carries both COSC chronometer certification (daily rate −4 to +6 seconds) and METAS Master Chronometer certification (daily rate 0 to +5 seconds) — the second standard is tighter, and the certification is applied to the complete assembled watch rather than the bare movement, which is a meaningful distinction. METAS also tests magnetic resistance up to 15,000 gauss and accuracy across six different positions.
The anti-magnetic performance is the headline specification. Conventional mechanical watches use a soft iron cage around the movement to deflect magnetic fields; the 8900 instead uses non-magnetic alloys throughout the escapement and a silicon balance spring, eliminating the need for the cage and allowing the exhibition caseback to exist. The result is a movement that can be worn near smartphones, laptops, airport security scanners and MRI machines without suffering the rate errors that typically plague high-precision watches in modern environments.
The 8900 is self-winding via a bidirectional rotor, runs at 25,200 vph (3.5 Hz), and has a 60-hour power reserve fed by twin barrels in series — a configuration that keeps torque consistent across the full reserve rather than tailing off as a single barrel winds down. The balance spring is silicon, which is not only non-magnetic but also dimensionally stable across temperature changes. Finishing is visible through the caseback: Côtes arabesques (Geneva wave) stripes on the bridges, black-polished screws, and a rhodium-plated rotor.
Gold models use Cal. 8901, which is mechanically identical to the 8900 but features a red-gold rotor and balance bridge for visual coherence with the case material. The practical performance of both is the same. For anyone who takes accuracy seriously, the Globemaster’s movement is a genuine differentiator from the competition at this price: the Rolex Datejust 36 uses the excellent but conventional Cal. 3235, which is COSC-certified but lacks the additional METAS layer and the extreme anti-magnetic performance of the 8900.
On the Wrist: Sizing and Daily Wear
The 39mm Globemaster wears closer to 38mm than 40mm in practice — the lugs do not extend aggressively outward, and the round case with tight lug curvature keeps the footprint minimal. On a wrist in the 6.5–7.5 inch range, it sits neatly without overhang. On a smaller wrist (6 inches or under) the 46.7mm lug-to-lug measurement will be noticeable; on a larger wrist (7.5 inches and above) the bracelet’s small, fine links may leave an uneven gap between the first and second link on the outer edge. The leather strap, available in alligator-pattern hide in several colours, resolves the fit issue entirely for most wrist sizes and is the preferred wear for this watch’s formal character.
At 12.6mm thick, the Globemaster slides under a standard dress shirt cuff without effort. It is meaningfully slimmer than the Omega Aqua Terra 150M (13.2mm), the Seamaster Diver 300M (13.8mm) and notably slimmer than the 41mm Annual Calendar variant (14.63mm). For buyers whose primary use is office and social wear, this profile is important — a watch that catches on your cuff every time you reach is one you leave at home. The Globemaster does not catch.
Day-to-day reliability matches the movement’s specification. The METAS anti-magnetic protection is invisible in daily life — by design, you never notice it — but for anyone who spends hours near computers, MRI equipment or industrial machinery, it means rate errors from magnetic exposure are not a concern. The 60-hour power reserve means a watch left on a dresser Friday evening will still be running Monday morning. The dial legibility is very good in most light conditions, with the pie-pan construction directing light onto the raised chapter ring while the lower central surface creates enough contrast for the markers and hands to read clearly.
The Annual Calendar Variant (41mm)
The 41mm Globemaster Annual Calendar is a different proposition. The 41mm case adds two millimetres in width and two millimetres in thickness, and the lug-to-lug extends to 49.8mm — this is a watch that will overhang a 6.75-inch wrist noticeably. The casework is also heavier, and the tungsten carbide bezel (standard on the steel Annual Calendar) gives it a more assertive presence. It does not wear like a slim dress watch. If the 39mm is a watch you could pair with a suit, the 41mm Annual Calendar is a watch that defines an outfit.
The complication itself is genuinely useful. The Cal. 8922’s annual calendar tracks the number of days in each month automatically for eleven of the twelve months — you correct it manually once a year, at the end of February. The month is displayed via a central hand pointing to cursive text around the dial edge; the date is in a window at 6 o’clock. The month hand is slim enough that it does not crowd the dial, and the italic month text integrates naturally with the pie-pan construction. Retail price for the steel Annual Calendar starts at $9,700 (silver dial) and goes to $11,200 for the burgundy two-tone version. The full-Sedna gold model is $31,000.
For the complication at this price, there is very little competition. Rolex’s Sky-Dweller, which carries a similar annual calendar displayed differently, starts above $18,000. Patek Philippe’s 5146G annual calendar is $30,000-plus. The Globemaster Annual Calendar delivers a legitimately useful complication, executed cleanly, at a price that sits inside the premium end of the mainstream market.
Globemaster vs Alternatives
Anyone researching the Globemaster is almost certainly also looking at these watches:
| Watch | Price (steel, leather) | Case size | Movement | One-line take |
|---|---|---|---|---|
| Omega Globemaster 39mm | $7,900 | 39mm × 12.6mm | Cal. 8900 (Master Chronometer) | Best movement in class; strongest technical case |
| Rolex Datejust 36 | $7,100 | 36mm × 12.4mm | Cal. 3235 (Superlative Chronometer) | Better resale; slightly slimmer; no anti-magnetic edge |
| Omega Constellation 39mm | $7,400 | 39mm × 13.1mm | Cal. 8800 (Master Chronometer) | Shared case family; integrated bracelet design; busier |
| Longines Conquest Heritage 38mm | $1,750 | 38mm × 11.7mm | Cal. L897 (COSC) | Far cheaper; excellent value; no METAS tier |
The Rolex Datejust 36 is the most obvious rival. It is slightly smaller (36mm vs 39mm), very slightly slimmer, has cleaner dial options and carries meaningfully stronger secondary market performance — a used Datejust 36 typically trades at or above retail, whereas the Globemaster sells at a 20–30 per cent discount to MSRP on the grey market. The Globemaster counters with a technically superior movement on the anti-magnetic and accuracy dimensions, a more distinctive design, and an exhibition caseback that the Datejust’s solid caseback cannot offer. If resale matters to you, the Datejust wins. If movement quality is the primary criterion, the Globemaster has the better argument.
The Omega Constellation shares the same movement family (Cal. 8800 rather than 8900, with equivalent Master Chronometer certification) but has an integrated bracelet design and a four-claw case attachment that is either a loved design quirk or a dealbreaker. The Globemaster’s design is more traditional and more versatile across strap options. If you already know you want an Omega dress watch with METAS certification and are not committed to the Constellation’s specific aesthetic, the Globemaster is the cleaner choice.

Price, Availability and Resale
The full reference range for the 39mm Globemaster in steel, as of October 2026:
| Reference | Dial | Strap/Bracelet | MSRP (USD) |
|---|---|---|---|
| 130.33.39.21.03.001 | Blue | Leather | $7,900 |
| 130.30.39.21.03.001 | Blue | Bracelet | $8,300 |
| 130.33.39.21.02.001 | Silver | Leather | $7,900 |
| 130.30.39.21.02.001 | Silver | Bracelet | $8,300 |
Omega authorised dealers do not discount, but the grey market and the pre-owned market both trade the Globemaster at meaningful savings. Grey market new-old-stock typically prices the steel Globemaster between $5,000 and $5,500 — roughly 30 per cent below retail. Pre-owned, lightly worn examples from 2020 onwards in good condition with box and papers are available in the $4,500–$5,200 range from reputable dealers. The resale performance is not strong by luxury watch standards — this is a watch that does not hold its value in the way a Datejust does — but for buyers who care about technical quality rather than investment potential, the grey-market price makes the Globemaster’s movement a remarkable proposition at under $5,500.
Availability at retail is generally good; the Globemaster is not an allocated or waiting-list watch. Authorised dealers carry it as a standard stock item in most markets. Service costs follow Omega’s standard schedule — the Omega service costs guide covers current interval and pricing expectations in detail. The 8900 calibre’s METAS certification requires specific tools and training; insist on an authorised Omega service centre for any movement work.

Yes, for the right buyer. The Cal. 8900 Master Chronometer is technically exceptional — dual COSC and METAS certified, anti-magnetic to 15,000 gauss, 60-hour power reserve — and the 39mm case wears beautifully at formal occasions. The main caveat is resale: the Globemaster trades at a 25–30% discount on the grey market, so buyers who prioritise value retention should consider the Rolex Datejust instead. If the movement and the vintage Constellation design are the draw, the Globemaster rewards the investment.
The 39mm carries Cal. 8900 and displays only hours, minutes, seconds and date. It is 12.6mm thick and available on both bracelet and leather strap. The 41mm carries Cal. 8922 and adds an annual calendar complication with a central month hand, making it 14.63mm thick and leather-only. The 41mm starts at $9,700 versus $7,900 for the 39mm steel. For everyday wear under a shirt cuff, the 39mm is the practical choice; the 41mm suits buyers who specifically want the complication.
The Datejust 36 costs slightly less ($7,100 vs $7,900), has stronger resale value, and offers cleaner dial options with simpler aesthetics. The Globemaster counters with a technically superior movement: the Cal. 8900 has METAS certification on top of COSC, and resists magnetic interference to 15,000 gauss — the Datejust’s Cal. 3235 is excellent but lacks those layers. The Globemaster also has an exhibition caseback showing the movement. See the full Globemaster vs Datejust comparison for a complete verdict.
The 39mm Globemaster works best on wrists between 6.5 and 7.5 inches. The 46.7mm lug-to-lug measurement means it can look slightly long on wrists under 6.25 inches. On wrists above 7.5 inches, the bracelet links may leave a visible gap near the clasp; switching to a leather strap resolves this on any wrist size. The 12.6mm case thickness fits under most dress shirt cuffs without catching.
The Cal. 8900 inside the Globemaster is certified anti-magnetic to 15,000 gauss under METAS testing. For comparison, standard mechanical watches (including the Rolex Datejust) use a soft iron inner cage rated to around 1,000 gauss. The Globemaster achieves its protection through non-magnetic alloys in the escapement and a silicon balance spring, with no cage needed — which is why the sapphire exhibition caseback is possible. This level of protection covers virtually all real-world magnetic sources: phones, laptops, speakers and even many industrial environments.
As of October 2026, the 39mm steel Globemaster trades on the grey market between $5,000 and $5,500 for new-old-stock, and $4,500–$5,200 for pre-owned examples in excellent condition with full box and papers. This represents a roughly 30% discount to the $7,900 retail price. Depreciation is consistent across references; the blue and silver dials are similarly priced second-hand. The Annual Calendar holds slightly better proportionally, given the complication’s value at retail.
Omega recommends a service interval of 8–10 years for the Cal. 8900, longer than the typical 5–7 year recommendation for many Swiss mechanical movements, owing to the movement’s Co-Axial escapement which produces less wear and requires less lubrication than a conventional Swiss lever escapement. Service should be performed by an authorised Omega service centre. For current service costs and what is covered, see the Omega service costs guide.
Final Verdict
The Omega Globemaster is a watch that rewards technical curiosity and rewards spending time with it on the wrist more than it rewards first impressions in a glass case. The pie-pan dial is not for everyone, and the fluted bezel has associations that some buyers would rather avoid. But strip those things away and what you have is a 39mm dress watch with one of the most capable movements in its price range, a proven track record for reliability, a 60-hour power reserve, and a caseback worth showing to people who understand what they are looking at.
Buy the Omega Globemaster 39mm if: you want Omega’s most technically accomplished movement in a slim, formal case; you wear your watch to occasions where a dive watch looks out of place; you appreciate the vintage Constellation design heritage; or you are buying pre-owned and consider the grey-market price ($5,000–$5,500) a compelling entry point for the 8900 calibre.
Look elsewhere if: resale value is a primary consideration (the Datejust is the better asset); you find the pie-pan dial or fluted bezel visually noisy (the Omega Aqua Terra or the Seamaster Diver 300M offer the same movement family in cleaner, sportier packages); or a 39mm case looks small on your particular wrist.
At retail, the Globemaster is correctly priced but not aggressively positioned — $7,900 for a watch that trades immediately at $5,000 is a hard argument unless you are buying from an authorised dealer for warranty reasons. At grey-market prices, the case for the Globemaster becomes considerably more compelling. The movement, at any price, remains the best in its class.
