Rolex Extension Systems

Rolex currently offers three different extension systems on their wristwatches, each extending the bracelet by varying lengths, depending on the model. No tools are required to adjust the lengths using these extensions, making it easy for the wearer to adjust whenever necessary.

The Easylink allows one to extend the bracelet by 5mm by unfolding a link tucked away under the clasp. Rolex's professional dive watches, the Submariner, Deepsea and Sea-Dweller 4000, are equipped with the Glidelock extension system.

The Glidelock extends the bracelet by 20 millimeters at 2 millimeter increments with a toothed panel under the clasp. On the Deepsea model, the rack can be lifted to adjust the length without taking off the watch. The Fliplock Extension, on the Deepsea and Sea-Dweller 4000, is a fold-out link that increases the bracelet by an additional 26mm.
