Everest has taken the time to develop the perfect replacement spring bar for the most recently released Rolex Datejust 41 (reference: 1126200, 126334, 126303, 126333, 126301, 126331). These spring bars are 1.5 mm thick and are designed to fit inside the 21 mm wide lug width of the Rolex Datejust 41. The Datejust that these were made for has a case width of 41mm. These spring bars will work both on the Everest rubber strap designed for this model or the bracelet that Rolex created for this Datejust 41.
