Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Promaster Diver

Owners widely praise the Citizen Promaster Diver for its affordability, lightweight titanium construction, and comfortable wear, noting its handsome dial made from recycled materials and excellent specifications for the price. Some owners express a preference for sapphire crystal and ceramic bezel inserts, and one example showed a slightly misaligned bezel and chapter ring. The bezel action is described by some as spongy, and the bracelet is considered subpar by one owner, with the overall finish being unremarkable due to its brushed titanium. Overall, owners rate the Citizen Promaster Diver highly for its value and comfortable, lightweight titanium build.

From video reviewers

The Citizen Promaster Diver is praised for its high value as an ISO-certified diver under $500. Reviewers note the comfortable fit due to its slim profile. The lack of a day complication was mentioned as a drawback.

CWC RN Quartz Divers Watch Mk.2, Matte Top

Owners widely praise the CWC RN Quartz Divers Watch Mk.2, Matte Top for its matte finish, precise seconds hand alignment, and old-school dial and hands reminiscent of vintage Omega. The Mk.2 upgrades, including a sapphire crystal, improved lume, and a precise 120-click bezel described as "perfection," are consistently highlighted. Some owners consider its toolish design and comfortable 11mm thickness a significant draw. However, a few find the £700-£900 price point high for a quartz watch, and one owner reported chipping on the PVD finish after a few months. One owner also noted the Ronda 517 quartz movement gained 8 seconds over several months. Overall, owners rate the CWC RN Quartz Divers Watch Mk.2, Matte Top highly for its robust, military-inspired design and significant Mk.2 upgrades at the price.
