⭐ TL;DR
The Oris Divers Sixty-Five is a vintage-inspired Swiss dive watch that earns its reputation through genuine watchmaking rather than marketing. The 40mm steel case, domed sapphire crystal, and period-correct dial design are executed beautifully at a price where competitors often cut corners. Choose the Cal 733 Date (~$2,750) for excellent value or step up to the Cal 400 (~$3,850) for five-day power reserve and a 10-year service guarantee. Our pick: the 40mm Date in blue.

Some watches earn their reputation once and coast on it for decades. The Oris Divers Sixty-Five is not one of them. Originally launched as a reissue of Oris’s first diver from 1965, the watch has been continuously refined since its 2015 comeback — gaining a Calibre 400 variant in 2023 and celebrating its 60th anniversary in 2025 with a commemorative no-date edition. The result is a vintage-inspired dive watch that keeps justifying its place in an increasingly crowded market.
For this review, we focus on the 40mm stainless steel lineup — the most versatile and widely available configuration. We evaluated both the Cal 733 Date and the Cal 400 variants to give you a genuine feel for how this watch lives on the wrist day-to-day, and where each version makes sense.
Design & History
Oris was founded in 1904 in Hölstein, Switzerland — a small town whose population was, at various points in the company’s history, largely employed by the factory. When they introduced their first proper diver’s watch in 1965, the design language was entirely of its era: chunky luminescent indices, a prominent rotating bezel, and a domed mineral crystal that gave the case a distinctly retro silhouette.
The modern Divers Sixty-Five captures all of this faithfully. The rotating bezel (bidirectional on pre-2026 production, correctly switched to unidirectional on 2026 models in line with ISO 6425) clicks with satisfying precision. The domed sapphire crystal — domed on both sides with anti-reflective coating inside — creates that distinctive lollipop-dial appearance that vintage divers are celebrated for. And the cushion-shaped case, with its aggressive lugs and stepped bezel surround, reads immediately as a watch from that golden era of dive watch design.
What makes the Sixty-Five compelling today is that Oris has resisted the urge to enlarge it. In an era when some dive watches push 47mm, the 40mm case feels like a considered design choice rather than a concession to modern taste. It sits flat on the wrist, disappears under a shirt cuff, and genuinely works as an everyday watch — something many tool divers cannot honestly claim. A 38mm variant is also available for those who prefer a slightly more compact presence, and Oris has offered the Sixty-Five in an extraordinary range of dial colours over the years, from classic blue and black to limited pastel “Cotton Candy” editions.
The 60th Anniversary Edition for 2025 — ref. 01 733 7772 4034-Set — distils the formula to its purest: no date, a two-tone blue-black dial, and a lacquered finish that looks stunning under direct light. It is the most collectible configuration in the current lineup and the one that most directly honours the 1965 original.

Cal 733 vs Cal 400: Which Should You Buy?
This is the central question for any Diver 65 purchase decision. The Cal 733 is Oris’s Sellita SW200-1 based movement — accurate, reliable, and widely serviced by independent watchmakers and Oris service centres worldwide. It has been the backbone of Oris’s affordable lineup for years, and it does its job without drama. The Cal 400, first introduced in 2020 and rolled out to the Diver 65 in 2023, is a fundamentally different proposition.
Developed entirely in-house at Oris’s Hölstein facility, the Cal 400 offers five days of power reserve (versus 38 hours for the Cal 733), an antimagnetic rating of 2,250 gauss that far exceeds everyday requirements, and a ten-year service interval guarantee from Oris. For a brand at this price point, that service guarantee is a remarkable claim — and one that fundamentally changes the economics of ownership if you keep watches for a decade or more. You’re looking at two service cycles avoided on a Cal 733 equivalent.
The Cal 400 versions cost approximately $1,100 more than equivalent Cal 733 models. Whether that premium is worth it depends on how you use the watch. If you plan to rotate it with others and prefer the classic no-frills ownership experience, the Cal 733 Date is entirely sufficient and leaves money for a quality watch winder — a well-made single-watch winder keeps an automatic running perfectly between wears. If you intend to wear the Diver 65 as a primary daily watch for the long term, the Cal 400 is the obvious choice — the movement quality is genuinely exceptional at this price.
The Oris Aquis Date benefits from the same Cal 400 movement, and its performance in heavier daily use confirms that Oris has genuinely cracked in-house production at a mainstream luxury price point. The Diver 65 Cal 400 brings that same engineering to a dress-casual package with considerably more vintage charm.
How It Compares to the Competition
The vintage diver space is crowded, but several names come up consistently when buyers are weighing the Diver 65 against alternatives.
| Watch | Case | Movement | WR | Price (approx.) |
|---|---|---|---|---|
| Oris Diver 65 Cal 733 Date | 40mm steel | Cal 733 / SW200-1 | 100m | ~$2,750 |
| Oris Diver 65 Cal 400 | 40mm steel | Cal 400 (in-house) | 100m | ~$3,850 |
| Tudor Black Bay 58 | 39mm steel | MT5402 (in-house) | 200m | ~$4,050 |
| Longines HydroConquest | 41mm steel | L888.4 | 300m | ~$1,800 |
| Tissot Seastar 1000 PM80 | 40mm steel | Powermatic 80 | 300m | ~$775 |
The Tudor Black Bay 58 is the Diver 65’s most natural rival — similarly sized, vintage-inspired, in-house movement, and beautifully finished. Tudor’s MT5402 movement is excellent, and the 200m water resistance gives the BB58 a genuine edge on dive credentials. But the Tudor costs approximately $1,300 more than the Cal 733 Diver 65, and the price gap narrows to around $200 when you compare it against the Cal 400 variant — where the Oris’s 5-day power reserve and 10-year service guarantee become genuinely competitive arguments. Our detailed Oris vs Tudor comparison covers this rivalry in depth for the tool diver category.
The Longines HydroConquest undercuts the Diver 65 significantly and offers 300m water resistance, but it’s a modern sport diver without vintage character — an entirely different purchase proposition. And at the accessible end, the Tissot Seastar 1000 Powermatic 80 represents extraordinary value if your diver budget is under $1,000, though it doesn’t compete with the Sixty-Five on finishing, crystal quality, or design heritage. If budget is the main concern, our best dive watches under $1,000 guide covers all the strong options at that level.
On the Wrist
The 40mm Diver 65 is one of those watches that wears smaller than its diameter suggests — which is a genuine compliment in the era of case-size inflation. The cushion case shape tucks in at the sides, the 20mm lug width is comfortably proportioned, and the domed crystal pulls the eye inward rather than making the watch feel larger. On a 7-inch wrist it sits perfectly centered; it remains accessible well below that.
Bezel action is a point of genuine satisfaction. Even the bidirectional versions — common on pre-2026 stock — click with precision and seat securely. The 2026 switch to unidirectional operation aligns the Diver 65 with ISO 6425 best practice and eliminates any concern about accidental elapsed-time advances during water activities. Collectors who prefer the original specification will find it readily available from retailers working through pre-2026 inventory or on the secondary market.
Lume performance is solid for a vintage-inspired watch. The applied indices and dauphine hands are generously sized, offering good low-light legibility for everyday use. For serious night diving or extended dark conditions, more technically focused divers offer brighter SPAD-indexed lume, but for casual marine activities — sailing, snorkelling, pool swimming — the Diver 65 is more than adequate. Those who need genuine 300m dive capability and a helium escape valve should look at Oris’s own Aquis line instead.
Strap versatility is where the Diver 65 genuinely excels. The 20mm lug width opens up an enormous aftermarket. Oris’s own leather and textile straps are excellent starting points, but the watch transforms on a quality 20mm NATO or canvas strap for summer or casual wear. The integrated steel bracelet — available on most Date models — is well-finished with a brushed/satin combination that avoids the budget look common on similarly-priced competitors from Longines and Tissot.
Verdict: Who Should Buy the Oris Divers Sixty-Five?
The Diver 65 is at its best as a daily-wear watch for someone who wants Swiss Made quality, a genuine vintage aesthetic, and real versatility without spending Tudor or pre-owned Rolex money. The Cal 733 Date at approximately $2,750 represents one of the strongest value propositions in Swiss dive watches at this price — better finished and more characterful than anything from Tissot or Longines at this level, with stronger design DNA than the Certina or Mido divers that compete on spec sheets alone.
Step up to the Cal 400 and you are investing in a watch you can realistically wear daily for a decade with minimal maintenance costs. This is the version we would recommend to someone buying their first genuinely serious Swiss watch, or to a collector who wants a workhorse piece they don’t have to think about. For those who want to learn about the broader Oris range before committing, our Oris Aquis buying guide explores the brand’s tool-diver lineup in detail.
One practical note: if you are travelling with the Diver 65, a quality leather travel watch roll is a worthwhile investment. The domed sapphire crystal is highly scratch-resistant, but a travel roll protects the bracelet from contact damage in luggage. Oris watches hold their resale value reasonably well for the price segment — the brand has genuine collector support, particularly for limited editions and Cal 400 variants.
If you are weighing the Diver 65 against the Panerai end of the spectrum, our Panerai Submersible review provides useful context on what the premium buys you in that price tier. For the Tissot buyer considering a step up, the Tissot buying guide maps out where the Oris sits relative to that brand’s best.
Yes. The Diver 65 remains one of the best-value vintage-style Swiss dive watches available. At approximately $2,750 for the Cal 733 Date, you get Swiss Made quality, excellent finishing, and genuine design heritage. The Cal 400 variant at ~$3,850 adds an in-house movement with a 5-day power reserve and a 10-year service guarantee — exceptional engineering at this price point.
The Cal 733 is based on the Sellita SW200-1 — a reliable movement used by many Swiss brands, offering 38 hours of power reserve. The Cal 400 is Oris’s own in-house calibre with 5 days (120 hours) of power reserve, anti-magnetic resistance to 2,250 gauss, and a 10-year service interval guarantee. Cal 400 versions cost approximately $1,100 more but offer significantly better long-term ownership economics.
For the vast majority of buyers, yes. 100m (10 bar) is sufficient for swimming, snorkelling, showering, and recreational water activities. It is not rated for scuba diving, which typically requires 200m or more. If you need a functional dive watch for underwater use, consider the Oris Aquis, which offers 300m water resistance and a helium escape valve in the same brand family.
The Tudor Black Bay 58 is the Diver 65’s most natural rival. Tudor’s MT5402 movement is excellent, and the BB58 has 200m water resistance versus the Diver 65’s 100m. However, the Tudor costs approximately $1,300 more than the Cal 733 Diver 65. The Oris wins on vintage character, strap versatility, and dial refinement at the same price tier. The Cal 400 Diver 65 closes the movement-quality gap significantly and still undercuts the BB58.
The most popular variant is 40mm with a 20mm lug width. A 38mm version is also available in both Cal 733 Date and Cal 400 lines. The 40mm wears smaller than its diameter due to the cushion case shape and suits wrists from approximately 6.5 to 8 inches comfortably. The dial design’s strong contrast and applied indices ensure legibility despite the moderate case size.
The blue dial is the most popular and versatile option — it shifts between deep navy and teal under different lighting and works equally well with casual and smart-casual wear. Black is the most legible and classically conservative choice. Brown dials look exceptional on a leather strap and evoke a stronger vintage feel. The limited Cotton Candy pastel editions are for collectors who want something unusual. All colours work well on the standard bracelet, though a vintage leather strap transforms any variant.
Reasonably well for a mid-range Swiss watch. Limited editions and Cal 400 variants retain value better than standard Cal 733 models. Oris has genuine collector support — the Sixty-Five name carries real provenance — and the brand’s secondary market values are respectable for the price tier. It won’t appreciate like a Rolex, but you’ll recover a meaningful percentage of purchase price if the watch is well maintained with original accessories and documentation.
