These crowns are generic and made to fit many of the popular U-Boat® brand watches. This makes an easy repair when you lose your crown and want to replace the part without having to send the watch in to the service center, saving shipping and insurance costs. These are generic made to fit and not to be confused with genuine U-Boat® watch crowns. Each crown fits a standard Tap 10 or .90mm thread diameter stem. These crowns cannot guarantee water resistance unless the watch is waterproof tested.
