Mechanical dive watches with a depth guage often work on water pressure . The IWC diver called the Deep One was the first Mechanical dive watch with a depth guage . This worked on the old Borden tube principle . The problem with any diver that uses water pressure on the depth guage , is of course salt and calcium deposits that can build up and block the inside of the guage . You just cannot remove calcium with any cleaning material except calcium remover . I have seen such a depth guage completly blocked with calcium and salt deposits . It is no big problem to remove these deposits using a vinigar acid , and it does not harm the watch . Willy
