With a square case, rounded edges and clean, uncluttered face, La Tétragone watch for women is a play on line, shape and form. With its timeless dark grey dial and silver coloured case and mesh strap this classic watch will never go out of style. As with all our watches in the La Tétragone collection, the straps of this model can be interchanged with any 16 mm CLUSE watch straps. To change the battery, we recommend visiting your local jeweller.
