Corum's iconic Admiral collection is dressed in black, thanks to the use of the famous 42 mm diameter by 10 mm thick dodecagonal case made of steel with a black PVD treatment. The dial, made of brass and guilloché engraved, is also black and features the famous nautical flags in place of the hour-markers, matching the colour of the hands, and available in blue, orange, red, yellow and green. At 6 o'clock are the small seconds. The movement used is the CO 395 calibre (11 ½'', 27 jewels, 28,800 vibrations per hour, 42-hour power reserve), mechanical with automatic winding. Water resistance is guaranteed up to 5 atmospheres and the strap, also black of course, is made of rubber. Each variant is produced in a limited series of 100 pieces.
