The phases of the moon, the curve of the tide, its functions (stopwatch with part-time, second time, timer, adequate lighting ...) this watch with its large well-contrasted digits really gives to his sub. Wrist is lightweight and can be worn in all circumstances, obviously this is not a luxury and a certain fragility (plastic glass among others) that requires you to be careful. Its battery is supposed to last 10 years, certainly not his bracelet but I notice that the attachment thereof to the casing is standard (18 mm width) and I think it should be fairly easy to cobble something cheap now come, obviously it will change its look.
