The Oris Divers Sixty-Five Calibre 400 in green is a 38 mm, no-date stainless-steel watch, reference 01 400 7774 4057-07 8 19 18. It pairs the vintage-inspired Divers Sixty-Five design with Oris’s automatic Calibre 400, which the brand rates for a 120-hour power reserve.
What is new about this Divers Sixty-Five?
Oris introduced this configuration on 18 June 2024. The defining change for readers seeking a simpler dial is the absence of a date: the green-dial model brings Calibre 400 to a 38 mm Divers Sixty-Five without a date display. Oris said the no-date version responded to requests from its community in its launch announcement.
The exact reference matters when shopping: other Divers Sixty-Five watches may differ in size, dial, movement, date layout, or bracelet. Oris lists this reference with a stainless-steel bracelet.
Specifications for reference 01 400 7774 4057-07 8 19 18
| Specification | Oris-listed detail |
|---|---|
| Case | 38.00 mm, multi-piece stainless steel |
| Dial and display | Green dial; hours, minutes, and central seconds; no date |
| Bezel | Unidirectional bezel with relief minute scale |

These are manufacturer specifications, not independent test results. The 10 bar rating is a stated water-resistance specification; it does not by itself establish suitability for a particular dive or activity. Oris also describes Calibre 400 as having elevated anti-magnetism, but the available product information does not give a numerical resistance threshold for this reference.

Calibre 400: reserve, warranty, and service are separate claims
Oris rates Calibre 400 for a 120-hour reserve, equivalent to five days. That is a manufacturer-stated figure, not a measured result for an individual watch. The product page lists a two-year warranty and says registration with MyOris can extend coverage to 10 years, subject to the brand’s registration terms. Separately, the launch announcement gives a 10-year recommended service interval for Calibre 400. A service recommendation is not an extension of the warranty.

Price and availability depend on the market
When accessed in 2026, Oris’s Greece regional product page listed the watch at EUR 3,600 and showed it as unavailable for online purchase through that storefront. This is a Greece-specific listing, not a universal price or confirmation of current stock elsewhere. Check the relevant Oris regional product page or contact an Oris store for local price and availability.

The watch’s interhorn width is 19 mm, and Oris lists leather, rubber, and textile strap options for fitting. Width alone does not confirm that every aftermarket strap will attach or fit correctly, so check the attachment and compatibility for the exact watch before buying.
