The 42mm stainless steel case carries a unidirectional bezel with a black anodized aluminium insert and a white-lumed dive scale, framing a matte black aluminium dial laser-engraved with the Diver's signature wave pattern. Skeletonized rhodium hands and indexes filled with white Super-LumiNova keep it legible in any light, and the helium escape valve and screw-down crown are there for genuine professional use. Turn it over and the sapphire caseback shows the Calibre 8806, a Co-Axial movement certified Master Chronometer by METAS and resistant to magnetic fields above 15,000 gauss. It's finished on a brushed steel mesh bracelet with a foldover clasp.\u003c\/p\u003e\n\u003cp\u003eThis example dates from 2025 and is in excellent pre-owned condition.
