Rolex Oysterclasp, Crownclasp and Oysterlock Clasps

The clasp of a wristwatch is meant to provide both security and comfort to the wearer. Having an expensive or rare timepiece slip off one's wrist is a nightmare and can often lead to irreparable damage. Rolex currently offers three clasp options on their wristwatches: Oysterclasp, Crownclasp and Oysterlock.

The Oysterclasp is the simplest of the clasp options, consisting of a folding clasp and a small lever that secures the clasp. The Oysterlock, shown in the photo above, was introduced in 2005 on the GMT-Master II model. This clasp features 15 micro technical components patented by Rolex for a secure clasp. It snaps shut, allowing the wearer to easily fasten and unlock it. The watchmaker added a crown design detail to the clasp that provides a small lip that can be gripped to open or close it.

The Crownclasp is the most inconspicuous of the clasp options, with a folding blade concealed by the bracelet, revealing only a crown shaped lever used to open and close the clasp. This clasp appears on the Jubilee bracelet as well as the President bracelet shown below in platinum.

Aside from the movement inside, the clasp of a wristwatch sees the most action. The opening and closing of the clasp on a daily basis wears on it and that wear could lead to an accidental opening later in the life of the timepiece. It is of utmost importance that watchmakers pay attention to this important detail. Perhaps Rolex places their crown logo on their clasps to let us know they are indeed paying attention.
