The in-house movement is the headline. At this price point, having a French-designed and assembled GMT calibre rather than a Sellita or Miyota is a genuine differentiator, and the YEMA3000 backs it up with 42 hours of power reserve and hacking seconds. The fully brushed case gives it a proper tool watch feel, and the bezel-lock at 3 o'clock is a Yema signature going back to 1963 — functional for diving, and a detail you won't find on anything else in this bracket. At 39mm with a 48mm lug-to-lug it wears well on 6.5"–7.5" wrists. The 19mm lug width is the one quirk — aftermarket strap options are slightly more limited than the standard 20mm, but it's manageable.
