We have been handcrafting replacement straps for the Poiray Ma Première watch for over 25 years. This strap is made with Mokuba ribbon, Swarovski crystals, and Miyuki beads. Approximately 18-20 Swarovski crystals are used on each side near the watch, and the rest is Miyuki beads. After purchase, we will create the strap to your preferred size, up to 136mm. The images after the first one show reference products.
