Hi everybody,

I've been searching the internet for dive watch brands which use crystal locking system. This system consists of a metal ring which screws over the crystal, keeping the crystal in place. I've been able to find some brands which use this system, but i'm sure there are many more. To name some of them: Seiko Marinemaster & Tuna, some older Doxa divers and Sjoo Sandstorm Landsort. If you came across other dive watches that use the same system, please share the information. Thanks.
