The case measures 13.72 mm thick with a lug-to-lug span of 49.9 mm, and a unidirectional rotating bezel surrounds the green dial. A domed sapphire crystal with anti-reflective treatment on both sides covers the dial. Inside is the self-winding calibre 8801, a Master Chronometer movement certified by METAS with 55 hours of power reserve. The date function sits alongside a screw-down crown and helium valve, and a display back shows the movement. The watch is fitted to a green rubber strap with a pin buckle in yellow gold. Rated to 300 metres, the case is built for serious depth.
