Seiko Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited EditionvsYema Navygraf Pearl CMM.20

The Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition features a 40mm case, 300m water resistance, and a 72-hour power reserve from the Calibre 6R55 movement, with a new grey bezel insert and a wave-patterned silvery-white dial. Owners find the watch attractive and the large case wears well without feeling bulky. However, some consider the price of €1900 for a 6R54 movement with an accuracy of +25/-15 seconds per day to be too high, and the production run of 6000 units is not seen as a true limited edition. Overall, owners find the Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition aesthetically pleasing with good wearability, but express concerns regarding its value proposition and movement accuracy for the price.

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.
