Baltic Prismic StonevsYema Navygraf Pearl CMM.20

Owners and reviewers widely praise the Baltic Prismic Stone for its striking and unique natural stone dials, with specific mentions of the bloodstone and red agate variants being highlights. The watch is noted for its refined, retro dress watch aesthetic, featuring a well-finished 36mm bi-metal case combining stainless steel and titanium, and a slim profile measuring 9.2mm or 9.5mm thick. The hand-wound movement, either an ETA Peseux 7001 or a La Joux-Perret D100, is generally seen as reliable, offering a 42-hour or 50-hour power reserve respectively. However, some owners find the collection overpriced and the small, recessed crown uncomfortable for winding. The Milanese bracelet is also a point of contention, with some finding it may not articulate well for smaller wrists. Accuracy figures vary, with one owner reporting +1/+2 seconds per day and another around -6 seconds per day.

The Yema Navygraf Pearl CMM.20 is praised for its elegant and slim case design, measuring between 9.5mm and 9.75mm thick, and its unique mother-of-pearl dial and bezel. The watch features functional dive watch elements like 200-meter water resistance and is powered by the in-house CMM.20 micro-rotor movement, which offers a 70-hour power reserve and is adjusted to -3/+7 seconds a day. Overall, reviewers highlight the Yema Navygraf Pearl CMM.20's sophisticated aesthetic and slim profile as its primary strengths.
