The Type 5 is the first mechanical watch to be perfectly readable underwater regardless of the viewing angle. The use of oil inside the upper part of the watch cancels out what is known as Total Internal Reflection. Typically, when under the water, a traditional diver’s watch needs to be viewed straight on in order to be read properly – otherwise refraction turns the glass into a mirror. But not with the oil-filled Type 5: this gives it complete legibility whatever the angle of view.

The organic design of the Type 5 takes its inspiration from nature, specifically sea turtles.

Their distinct aqua-dynamic shape means they are best able to propel themselves easily through the water – so what better shape too for an amphibious watch, right down to its seamlessly integrated uni-directional bezel? The watch is made from titanium ensuring that it is also lightweight – just 87g – and extremely comfortable to wear.

The watch is graphically very strong -for improved readability -and is the ideal watch for the gentleman diver, whether he’s in the water or around town.
