SJ Productions 8+Factory presents a new masterpiece: the Rolex Constant Motion Series RB2. This ultra-thin 90g weighted version features a two-and-a-half hand business style. The Rolex Constant Motion 1908 model measures 39mm in diameter and 9.8mm in thickness. It is exclusively customized with a modified Chronergy escapement system and a blue Syloxi balance wheel hairspring, powered by the Cal.7140 automatic movement. The 18K gold and steel stamped folding clasp provides an experience closer to that of wearing a gold watch. S1 exquisitely recommends this two-and-a-half hand mechanical watch for men.
