Water Resistance, Case, Dial

The rich green dial of the Oris Aquis Date Calibre 400 Watch exudes calm. With an impressive 300-metre water resistance, this model is ready to explore deep below the ocean’s surface. Firstly, the multi-piece stainless steel case is 41.50mm in diameter with an 18ct gold turning top ring with ceramic minutes scale top ring for effectively measuring elapsed time underwater. Secondly, the green sunray dial has bold, white hour markers. Along with the hands, these are coated in superluminova for legibility in poor light. Additionally, a white minute track ensures the dial is easy to read. Finally, a domed anti-reflective sapphire crystal protects the dial.

Power Reserve, Caseback, Bracelet

The Oris Aquis Date Calibre 400 Green Dial Watch has an incredible 120 hour power reserve which is very useful for anyone who doesn’t wear their watch every day. Also, it has an easy grip screw-down security crown. Similarly, the see-through sapphire crystal caseback also screws-in and grants a clear view into the performance of the Calibre 400. Finally, the green rubber strap has a folding clasp with diving extension facility for wearing over the top of a heavy diving suit.
