Oris’s US product page lists it at $4,500. The available product information establishes its specifications, but not hands-on performance or wear impressions.
What is the Oris Divers Sixty-Five Chronograph in Ocean Green?
It is Oris reference 01 771 7791 4051-07 6 20 01, a neo-vintage-styled chronograph in the Divers Sixty-Five line. Oris describes the design as having “Ocean-green detailing and a silver sunray dial”; its technical listing calls the dial grey. The watch has pump-style chronograph pushers and a minutes-scale top ring.
The product page’s color description is Oris’s own marketing language, not an independent assessment of how the dial or accents appear in different lighting.
What are its size and case specifications?
- Case diameter: 40 mm.
- Case: Multi-piece stainless steel.
- Crystal: Domed sapphire on both sides, with anti-reflective coating on the inside.
- Interhorn width: 20 mm.
- Caseback: Screwed stainless steel with special engravings.
Oris’s retrieved product details do not state the case thickness, so it is not possible to assess that dimension or give a complete size comparison from those details alone.

- Approximate power reserve of 38 hours.

What movement does it use, and how does the chronograph work?
The watch uses the automatic Oris Calibre 771-1, with a red rotor. Oris lists a 62-hour power reserve and a frequency of 28,800 A/h (4 Hz).
The display includes central hour, minute and chronograph 1/4-second hands. Two subsidiary dials show continuous seconds and a 30-minute chronograph counter. The movement also has a stop-second function. These are manufacturer-listed specifications; no independent timing or chronograph-performance test is established here.
Rank #2
- Set Contents: Main unit, Box, Warranty
- Movement: Quartz (solar powered)
- Accuracy: monthly deviation within ±20 seconds
- Operation time: about 6 months
- Country of Origin: Japan (Made in Japan)
What does the 10-bar water-resistance rating mean?
Oris specifies water resistance of 10 bar. That is the manufacturer’s rating, not evidence of an independent depth test or a guarantee of suitability for a particular dive. Follow the current manufacturer guidance for use and care rather than treating the rating as a tested real-world diving claim.
Can you change the strap, and what width does it take?
The listed interhorn width is 20 mm. Oris shows the watch on leather and lists fitting leather and textile straps, as well as a stainless-steel bracelet, in that nominal width. A third-party strap still needs a fit check: width alone does not establish that its end shape or attachment interface will work with this watch.

How much does the Ocean Green Chronograph cost?
Oris’s official US product page lists the exact reference at USD 4,500. This is a manufacturer listing for the US market, not a guaranteed transaction price elsewhere or a confirmation of current stock. Check the current regional listing and availability before buying; other Divers Sixty-Five Chronograph variations on Oris’s page have different prices.
What warranty does Oris list?
The product page lists a two-year warranty and says MyOris registration can extend it free to three years. A separate warranty-extension section on that page says three-, five- or ten-year coverage depends on the movement. Because the page presents these durations in different contexts, confirm the applicable term, eligibility and conditions in the current MyOris terms for this specific reference.

What the published specifications can—and cannot—tell you
The manufacturer’s page is useful for identifying the reference and its listed dimensions, movement, display, water-resistance rating and accessories. It does not establish accuracy in use, comfort, finishing quality, dial legibility, chronograph performance or suitability for a particular dive. Those questions require evidence beyond the listed specifications; no hands-on test is claimed here.
