A screw-in crown is a type of watch crown that is screwed into the watch case instead of being pressed or snapped on. This extra secure design helps to protect the internal components of the watch from dust and moisture, making it a popular choice for divers and other adventurers who need a secure and reliable timepiece. The screw-in crown can be easily unscrewed with a special tool, allowing for quick access to the inner workings of the watch for maintenance or battery changes.
