Same ceramic case, same 41mm, same 200m rating as the black-dial version — the only real variable here is the blue dial, and on a watch this stripped-down, dial color is doing most of the character work since there's no GMT hand or chronograph subdial to distract from it. The scratch-resistant ceramic bezel is the material choice that actually matters long-term; steel bezels on watches this size show wear within a couple of years of regular use, ceramic doesn't. Leather-and-rubber strap, manufacture automatic movement. Reference M79210CNU-0007.
