The Oris Divers Sixty-Five is one of the watch world’s great accessible classics: a 1960s-inspired dive watch that does not ask you to choose between heritage styling and serious mechanical credentials. Yet buying one in 2026 means navigating four size variants, two movement families, and a 60th Anniversary Edition that muddies the waters for first-timers. This guide cuts through every option so you leave knowing exactly which Divers Sixty-Five belongs on your wrist.
TL;DR — Which Divers Sixty-Five?
- Best value: Cal 733, 40mm Date (~$2,750) — proven Sellita base, classic domed crystal, no fuss.
- Best all-rounder: Cal 400, 40mm (~$3,850) — 5-day power reserve, 2,250-gauss anti-mag, 10-year service interval.
- Small wrists: Cal 400, 38mm (~$3,500) — same in-house movement, more comfortable under a shirt cuff.
- Collector pick: 60th Anniversary Edition (~$2,950) — no date, two-tone blue-black bezel, strictly limited.
- Skip it if: the budget is under $2,000 — the Longines HydroConquest (~$1,800) delivers 300m WR at a fraction of the Cal 400 price.

What Is the Oris Divers Sixty-Five?
The Divers Sixty-Five debuted in 2015 as a deliberate callback to Oris’s 1965 diver, the reference 7206. Where the modern variant earns its keep is in the details: a cushion-shaped 40mm steel case (or 38mm for a closer match to the vintage dimensions), a steeply domed sapphire crystal with anti-reflective coating on both sides, and a bezel that gained a strictly unidirectional rotation in 2026 — a welcome upgrade that finally brings it in line with ISO 6425 best practice. Both the dial and case are finished to a standard that punches above the price point, with brushed flanks meeting polished bevels in a way that reads as expensive under direct light.
Oris’s identity has always been mechanical independence, and the Divers Sixty-Five is the brand’s clearest statement of intent. The entry-level version uses a regulated Sellita SW200-1 (Cal 733), but the top of the line deploys Oris’s own Cal 400 — an in-house movement that rivals calibres costing twice as much. The watch is offered on a bracelet or a rubber strap, with bracelet wearers getting a diving extension for use over a wetsuit. For a deeper look at how the watch performs day-to-day, see our full Oris Divers Sixty-Five review.
38mm vs 40mm: Which Size Should You Choose?
Both cases share the same 20mm lug width, so strap compatibility is identical. The practical difference is almost entirely about dial presence and wrist fit. The 40mm case wears closer to 47mm lug-to-lug, which suits wrists from about 16.5cm upward. The 38mm case suits smaller wrists perfectly and disappears under a shirt cuff more graciously — making it the natural choice if you plan to wear the Divers Sixty-Five in professional settings as well as casual ones.
The 38mm also tends to look more proportional against the vintage inspiration; the original 1965 reference was a compact 36mm, so the 38mm closes that gap aesthetically. From a practical standpoint, water resistance and crystal quality are identical across both sizes, so there is no performance penalty for going smaller. The key financial note: the 38mm Cal 400 saves you roughly $350 over the 40mm equivalent at approximately $3,500, making it the most mechanically capable option in the line-up at the lowest price. If you are torn between size and specification, the 38mm Cal 400 resolves the dilemma.
Cal 733 vs Cal 400: The Movement Decision
This is the central question for most buyers. The Cal 733 is a regulated Sellita SW200-1: a workhorse movement with a 38-hour power reserve, industry-standard anti-magnetic protection, and a time-tested reliability record going back decades. Sellita movements are serviced by qualified watchmakers everywhere on the planet. If you want a no-drama daily wearer and want to keep the purchase price south of $3,000, the Cal 733 is the honest choice.
The Cal 400 is a different proposition. Developed entirely in-house at Oris’s Hölstein facility, it offers 120 hours (five days) of power reserve — a significant real-world advantage for weekend-off wearers — and an anti-magnetic shield rated to 2,250 gauss, high enough to shrug off MRI-adjacent fields. The headline argument, however, is the service interval: Oris backs the Cal 400 with a ten-year service guarantee, halving the lifetime cost of ownership compared to most Swiss mechanicals. When you amortise that saving over a decade of wear, the $1,100 premium over the Cal 733 becomes considerably easier to justify. For buyers planning to keep the watch long-term, the Cal 400 is the one to buy.

On the Wrist
The 40mm case measures approximately 47mm lug-to-lug with a moderate 13mm height — figures that keep it clear of the overwrought proportions that plague too many modern dive watches. The domed crystal adds an optical depth to the dial that flat sapphire cannot replicate; in sunlight, the blue dial takes on a shifting aquatic quality that justifies the Divers Sixty-Five name beyond pure marketing copy. The crown at 3 o’clock sits close to the case, avoiding the wrist-dig that plagues screw-down crowns on competing designs at this price.
Bracelet comfort has improved across the 2026 iteration, with tighter tolerances reducing the play that earlier generations attracted criticism for. On the leather strap — Oris includes a canvas-backed leather alternative in some configurations — the watch moves effortlessly from poolside to a business meeting, a versatility that fewer dive watches at this price genuinely offer. Legibility is strong: the broad baton indices and wide bezel numerals are designed for underwater reading, and they work just as well under a conference-room projector.
How It Compares: Competitors and Alternatives
The Divers Sixty-Five lives in a crowded bracket, but its combination of vintage styling and genuine in-house movement options gives it a specific character that rivals struggle to match at the same price.
| Watch | Price | Size | Movement | WR | Advantage |
| Oris D65 Cal 400 | ~$3,850 | 40mm | In-house, 120h | 100m | Best heritage + in-house at price |
| Tudor BB58 | ~$4,050 | 39mm | MT5402, 70h | 200m | Better WR, stronger resale value |
| Longines HydroConquest | ~$1,800 | 41mm | L888.4, 72h | 300m | Best performance per dollar |
| Tissot Seastar 1000 | ~$775 | 40mm | Sellita PM80 | 300m | Entry price, workhorse spec |
The Tudor Black Bay 58 is the most direct competitor for buyers who prioritise water resistance and resale value over vintage aesthetics. At roughly $200 more than the Cal 400, the decision hinges on whether 200m WR matters to your use case. The Longines HydroConquest is the budget counterpoint: it delivers 300m WR and a COSC-adjacent movement for $2,000 less than the Cal 400, making it the sensible choice when the budget does not stretch to Oris territory. If you want to stay in the Oris family but need a sportier specification, the Oris Aquis steps up to 300m WR with a more contemporary case profile.
Price, Availability, and Resale
Authorised dealer discounts on the Divers Sixty-Five are modest by Swiss watch standards — most ADs hold close to MSRP because sell-through is strong and grey-market pressure is limited. You may find 10–15% below MSRP on the Cal 733 from established grey-market dealers, which brings the 40mm Date to around $2,350–$2,450. The Cal 400 retains its premium more stubbornly; $3,400–$3,600 is typical grey-market pricing.
Resale has been steady rather than spectacular: pre-owned Divers Sixty-Five Cal 733 models typically trade at 60–75% of MSRP, while Cal 400 examples hold closer to 70–80% thanks to the in-house movement’s appeal to secondary buyers. The 60th Anniversary Edition already trades at or above MSRP in mint condition on Chrono24, reflecting its constrained supply. Pre-owned Cal 733 examples are plentiful; Cal 400 supply is thinner, which keeps prices firmer.
Where to Buy
For new stock, the cleanest path is Oris’s own website or an authorised dealer — Oris offers a five-year warranty on all new watches and the Cal 400’s ten-year service guarantee requires AD purchase documentation. If you are comfortable with grey-market pricing and want to save on the Cal 733, established grey-market sellers with return policies are a legitimate route; just confirm the bracelet is fitted with the dive-extension clasp if you plan to wear it over a wetsuit.
The Cal 733 40mm Date is available on Amazon through Oris-authorised sellers with Prime shipping. Check the current price on Amazon (Oris Divers Sixty-Five Cal 733 Date — ASIN B0GNL4T6J4).
Pre-owned buyers should target sellers who provide service records and guarantee the bracelet clasp adjustment pin — the most commonly missing piece on well-worn examples. Chrono24’s buyer protection and WatchBox’s certified pre-owned programme both offer meaningful recourse if a watch arrives misrepresented.
Frequently Asked Questions
For most buyers, the Cal 733 40mm Date (~$2,750) is the ideal entry point. It uses a regulated Sellita SW200-1 — widely serviceable and proven reliable — paired with the full Divers Sixty-Five package: domed crystal, 100m WR, and the 2026 unidirectional bezel. If the budget stretches, the Cal 400 38mm (~$3,500) is the technical sweet spot: in-house movement and the 10-year service guarantee at the lowest price in the Cal 400 family.
At ~$2,950, the 60th Anniversary Edition costs approximately $200 more than the standard Cal 733 40mm Date but uses the Cal 733 without a date complication. Its value is primarily collectible rather than technical: supply is constrained and it already commands a secondary market premium. If you want the strongest daily driver, the Cal 400 is the superior functional buy. If you want something with future collectible potential, the Anniversary Edition makes more sense — but act before allocations dry up.
Authorised dealers and Oris’s own website offer the manufacturer warranty but discount rarely beyond 5–10%. Grey-market dealers typically offer 10–15% below MSRP on Cal 733 models. Amazon’s Oris-authorised listings sometimes run promotional pricing on the Cal 733 Date (ASIN B0GNL4T6J4) with Prime shipping included. Pre-owned Cal 733 examples on Chrono24 can be found for $1,800–$2,200 in excellent condition, representing the best absolute value for buyers comfortable without a factory warranty.
The Cal 733 (Sellita SW200-1 base) follows the standard Swiss mechanical recommendation of a service every three to five years depending on use conditions and environment. The Cal 400 carries Oris’s ten-year service guarantee, backed by the movement’s silicon escapement and optimised lubrication geometry. This halves the expected service cost over a decade of ownership — a genuine financial argument for the Cal 400’s higher purchase price that many buyers underestimate when comparing sticker prices alone.
Yes — the Divers Sixty-Five is one of the better pre-owned propositions in this price bracket. Supply of Cal 733 examples is strong, keeping prices competitive. Look for examples with service records and an intact bracelet (the dive-extension clasp pin is commonly lost on worn examples). A pre-owned Cal 733 40mm in excellent condition typically fetches $1,800–$2,200, representing 25–35% savings over new MSRP. Pre-owned Cal 400 supply is thinner, so savings are more modest at 15–20% below new pricing.
The 20mm lug width makes the Divers Sixty-Five one of the more accommodating watches in the vintage-inspired dive category. Oris offers rubber, leather, NATO, and steel bracelet configurations through its boutiques and ADs. Third-party options in NATO, leather, and rubber from Worn & Wound, HIRSCH, and Strapcode are excellent fits. The original curved-end bracelet is proprietary to Oris, so any third-party strap will sit slightly higher — a minor aesthetic trade-off for access to hundreds of aftermarket options at a fraction of the bracelet price.
The Verdict
The Oris Divers Sixty-Five holds its ground in 2026 because it offers something genuinely rare: a credible in-house movement at a price that does not require a financial justification conversation. The Cal 400 is the version to buy if you can reach the budget — its ten-year service interval and five-day power reserve make it an ownership proposition that competes well above its price point. The Cal 733 remains the honest, no-drama choice for buyers who want the aesthetics and the brand story without the in-house premium.
What the Divers Sixty-Five is not is a deep-dive technical instrument — 100m WR is comfortable for swimming and snorkelling, not for scuba or freediving. If a genuine diving tool is the goal, the Oris Aquis or the Tudor Black Bay 58 serve that brief better. But as a daily wearer with a genuine mechanical story, a 1960s-inspired aesthetic that wears across every context, and an in-house movement option that justifies its asking price on its own terms, the Divers Sixty-Five deserves every word written about it.
