Gruppo Gamma Vanguard SteelvsYema YEMA x Silberstein Marine 2 CMM.20 Limited Edition

The Gruppo Gamma Vanguard Steel is praised for its aged steel case and cream sandwich dial. However, some owners dislike the distorted sapphire crystal and the absence of minute markers, with one noting difficulty in replacing the crystal due to hand fitment. The watch features a Miyota 9039 movement with a 42-hour power reserve and an accuracy range of -10 to +30 seconds per day, and is offered with two strap options. On balance, owners value the Gruppo Gamma Vanguard Steel for its distinctive aged aesthetic and dial design, despite some reservations about the crystal.

The YEMA x Silberstein Marine 2 CMM.20 Limited Edition is noted for its slim 39mm case and in-house CMM.20 micro-rotor movement, offering 300 meters of water resistance and a 70-hour power reserve. Reviewers highlight the watch's thin profile and flowing case design, as well as its black lacquered enamel dial. However, the bezel's lack of numbers is considered a practical drawback, and one reviewer noted the audible spin of the micro-rotor, which was unexpected given the €1,990 price for the 200-piece limited edition. The included leather strap is also seen as less suited for the watch's dive capabilities. Overall, reviewers appreciate the YEMA x Silberstein Marine 2 CMM.20 Limited Edition for its slim design and in-house movement, though practical considerations regarding the bezel and strap are noted.
