YEMA Superman Slim CMM.20

The Superman Slim CMM.20 brings the Superman’s dive-watch DNA to an ultra-thin case, made possible by YEMA’s French-made CMM.20 micro-rotor caliber, only 3.7mm thick thanks to its bidirectional tungsten micro-rotor. Built around a non-magnetic Glucydur balance wheel, the movement delivers roughly 70 hours of power reserve and near-chronometer accuracy, and can be admired through a sapphire exhibition caseback. The unidirectional diving bezel and Super-LumiNova-treated markers and hands keep the model’s professional dive-watch character, while the slimmer 39mm stainless steel case, fitted with a sapphire crystal, sits noticeably flatter and more comfortably on the wrist than earlier Superman generations.
