Screw Down Threaded Watch Crowns
Screw down or threaded crowns are very common in water proof watches to help keep any moisture out of the watch. They also provide extra security and cannot be easily knocked off or pulled out and lost. Threaded watch crowns are perfect to use on both generic and brand name watches. Crowns come complete with a threaded case tube. Case tubes are threaded on the crown end and have a smooth friction fit on the case end.
