9mm x 9mm "GLIDELOCK " BRUSHED PINK / ROSE GOLD / SILVER Deployment Buckle Clasp , fit For Rolex GMT Submariner The Rolex Glidelock clasp is very often confused with the Oysterlock clasp itself. While it looks rather similar to the Oysterlock, the Glidelock clasp is much longer. Concealed within it is a truly fantastic extension system. This extension allows divers to expand the band by approximately 20mm in precise 2mm increments. Additionally, the Fliplock extension links on the Sea-Dweller and Deepsea models enable the bracelet to be adjusted by a further 26mm. As such, wearers can quickly adjust the watch to be worn comfortably over a thick diving suit.
