Maen Greenwich 38 GMTvsYema Diver

Owners and reviewers widely praise the Maen Greenwich 38 GMT for its elegant 38mm sizing, exceptional case finishing, and flawless enamel dial. The SwissTech S24-045 movement is noted for its smooth winding and accurate timekeeping, with figures ranging from zero deviation to +7 seconds per day, though its 40-hour power reserve is considered unremarkable. Some owners find the hour markers too bold, the GMT hour markings difficult to read, and the GMT hand alignment slightly off, while one user experienced crown resistance and movement stoppage. The lug-to-lug measurement is reported to make the 38mm case wear slightly larger. Overall, owners and reviewers rate the Maen Greenwich 38 GMT highly for its premium finishing and design at its price point.

One owner reported a water ingress issue on their Yema Diver the first time it got wet in a lake, despite rinsing and inspecting the watch and bezel. Another owner notes this manual wind Yema Diver has a cool patina but is unlikely to be waterproof or gain value. Overall, owners view the Yema Diver as a fun second watch rather than an investment.
