Aquis Date Calibre 400 Automatic Green Dial Rubber Strap Men's Watch 01 400 7769 4127-07 4 22 77FC

Let’s talk date. Oris places it at 6 o’clock, where it becomes part of the lower dial instead of pulling your eye toward one side. Minute markings run around the outer edge, giving the face a precise border. The overall layout reads quickly, which is exactly what you want from an Aquis. There’s detail here, but every piece has a job.

Around the dial is a ceramic bezel with a unidirectional ratcheting action. Ceramic gives the bezel a smooth, dense appearance beside the steel case and handles regular wear well. The screw-down crown reinforces the dive-watch construction at the side. Sapphire crystal covers the front. Oris went with brushed and polished steel across the case. This gives the surfaces enough variation to show off the unusual Aquis shape.

The green rubber strap gives the watch a secure, flexible contact point on the wrist and works naturally with a sports case of this size. A folding clasp adds a more substantial closure than a basic buckle. Once everything is together, the strap seems like part of the overall case design.

The Oris Aquis Date Calibre 400 gives mechanical-watch fans a lot to enjoy in a very usable package. The 120-hour reserve is the headline specification. The green dial gives the watch its identity. The yellow gold-tone hands add an unexpected warmer detail. At 41.5mm, it has enough size for a serious dive watch that many collectors can wear comfortably every day.
