The Marine-Officer Blue is a modern interpretation of an observer chronograph that was developed towards the end of World War II for deck officers of the Italian Navy. The wide bezel of the finely brushed stainless steel case provides sufficient space for the engraved tachymeter scale, which can be used in conjunction with the chronograph to determine the speed of moving objects. The reduced dark blue dial ensures good readability, which is also given in darkness due to the indices and brushed silver hands being painted with C3 Superlumiova. Our Marine-Officer Blue is powered by a wonderfully decorated Swiss chronograph module caliber, the Dubois Dépraz DD 2030 which is automatically wound by our skeletonized gold rotor. This process can be observed through the stainless steel encased glass case back by gently shaking the watch.
