Yema Superman Steel 39mm 11.13.66.SN.M2

The Superman Steel returns with a steel-blue sunray-finished dial and polished applied indices, lending greater depth and contrast to YEMA's emblematic professional diver's watch. Its 39mm steel case combines the Superman's signature bezel-lock mechanism with a polished ceramic insert and 30 BAR water resistance, while the sapphire exhibition caseback reveals the Manufacture CMM.10 caliber, offering chronometric precision and a 70-hour power reserve.
