Pulsar watch with a diving look. diameter of the watchcase without the crown is ca. 43mm. the thickness of the watch is 12mm. The watch has a slightly curved mineral glass. The watch is waterproof till 100 Mtr. It has a bezel which doesn't rotate. Therefore I call it a diving look watch not a diving watch. Diving watches are waterproof till 200 mtr. Thi s one is only waterproof till 100 M.
