The new Supermarine 300m and 300m Date models have been entirely redesigned and now feature a new, sleeker and slimmer profile case shape crafted in 904L steel to maximise robustness and comfort in unison.


This new symmetrical case silhouette includes both crown and bezel guards, ensuring practical operation whilst increasing durability and safety by preventing accidental adjustment or damage through shocks or knocks.


The anodised aluminium knurled edged bezel features trapezoid indexes which flow from the bezel onto the dial, forming a naval inspired cross-hair, drawing the eye to the centre of the striking gradient dial. This is combined with improved durability, the clarity of applied indexes and the use of Super-LumiNova® for visibility in low light conditions.


An entirely new 904L steel bracelet has been developed for the Supermarine range offering exceptional fluidity and quality with an undulating shape which is well suited to all wrist sizes. Infinity shaped links alternate in a polished and satin finish. The watch is also available with a new military influenced chevron performance rubber strap or a vintage brown leather lifestyle strap with top stitching.


The case back is engraved with a map of the world’s oceans, emphasising the intent of the this practical elegant sports watch.


Green rubber strap with pin buckle clasp. Standard length strap, fits 16.5cm to 22cm wrists.
