Ref. 01 400 7769 4157
Status: Active Investigation
Condition: Very Nice Pre-Owned
Scope: Box, Papers, and Cards
Year: 2025
The Oris Aquis Date Calibre 400 Ref. 01 400 7769 4157 is one of the strongest modern everyday divers in Orisโs lineup โ clean, capable, and built around the brandโs in-house Calibre 400 platform. This reference is part of the 41.5mm Aquis Date Calibre 400 family with a stainless steel case, ceramic bezel insert, sapphire crystal, and 300m water resistance.
This example is presented in very nice pre-owned condition and comes as a complete kit from 2025. A major plus here is the included steel bracelet and rubber strap, giving the watch two very different personalities: bracelet for a sharper daily-wear look, rubber for a more tool-forward dive setup.
The green dial brings just enough color to separate it from the sea of black and blue divers without sacrificing versatility. Itโs still unmistakably Aquis โ modern, solid, and easy to wear โ but with a little more life on the wrist.

The Aquis has long been one of Orisโs strongest modern platforms, but the Calibre 400 generation pushed it further by pairing the familiar integrated-case diver design with Orisโs in-house movement architecture. The result is a watch that feels more substantial in the collector conversation while still keeping the Aquisโs daily-wear practicality.
Examples with both strap options and a 2025 complete set are especially appealing, since they give the next owner the full flexibility of the platform right out of the box. The green-dial Aquis Calibre 400 also stands apart from more common mainstream diver colorways without becoming difficult to wear.
Oris has built a strong following among collectors who appreciate independent Swiss watchmaking, practical dive capability, and modern, design-forward tool watches.
โRecovered in very nice pre-owned condition as a complete 2025 set. Includes both steel bracelet and rubber strap. A strong modern Aquis with added flexibility and collector-friendly presentation.โ
Case #307 delivers one of Orisโs most compelling modern divers in a particularly versatile configuration. With its Calibre 400 movement, green dial, steel bracelet and rubber strap, and complete 2025 set, it stands as a highly wearable independent-brand diver with real everyday appeal.
๐ Every case deserves a closer look.
