SJ Production presents the new masterpiece from 8+Factory: the Rolex Perpetual Series RB2. This ultra-thin 90g weighted version features a two-and-a-half-hand business style. The Rolex Perpetual 1908 model comes in a size of 39mm and a thickness of 9.8mm. It boasts an exclusive customized Chronergy escapement system with a blue Syloxi balance spring, powered by the Cal.7140 automatic movement. The gold and steel stamped folding clasp enhances the feel and wearing experience, closely resembling that of a solid gold watch. The S1 is a refined recommendation for men's two-and-a-half-hand mechanical wristwatch.
