rolexさんのインスタグラム写真 - (rolexInstagram)「The 60-minute graduation on the bezel of the Rolex Deepsea and Sea-Dweller professional divers' watches has minute marks throughout the scale, whereas on the Submariner, only the first 15 minutes are detailed up to the minute. This is because the detailed scaled is used by divers to precisely time their decompression stops, and the deeper and longer the dive - such as those by technical divers - the more time is required for decompression. #Rolex #SeaDweller #101031」10月10日 0時30分
