Yema Superman Steel Blue CMM.10 puts a sunray dial inside a 300-metre diver

Yema’s September 2026 Superman Steel Blue CMM.10 brings a restrained sunray finish to its established diving-watch architecture. Applied markers and a lollipop seconds hand sit against a blue dial, framed by a black ceramic bezel insert. The familiar crown-operated bezel lock remains part of the design.

The 39mm steel case measures 11.3mm thick, with 47mm lug-to-lug proportions and a double-domed sapphire crystal. Inside, the automatic CMM.10 provides a stated 70-hour power reserve at 4Hz. Water resistance is 300 metres. The steel-bracelet version uses Yema’s Scales Slim bracelet with on-the-fly clasp adjustment.
