Double O-Ring Flush Medium And Long Post Divers Waterproof Watch Crowns

 These double O-ring crowns are generally thicker than standard crowns. The thickness of the crown allows for the O-ring gaskets to be stacked inside on the flush posts and the long posts have 1 inside the crown and 1 on the post to provide better water resistance. Generally used but not limited to diver style watches. With 11 different sizes to choose from you should be able to find a suitable replacement to fit your watch. Most of these crowns fit the standard thread size 0.90mm or Tap 10 with a couple Tap 8 and Tap 6 available for the older model watches. Made to fit 2.0 and 2.5mm case tubes.
