Reviews

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

CWC RN Automatic Divers Watch Mk.2 with Date

Owners widely praise the CWC RN Automatic Divers Watch Mk.2 with Date for its authentic vintage look and legible dial, with reviewers noting its faithful homage to the 1980 original and durable 41mm case. The watch features an upgraded sapphire crystal and improved lume, and its 120-click bezel is described as perfectly clicking. Some find the vintage-tinted dial and hands' gold tone slightly too pronounced and the applied paint too glossy, while the day/date function draws mixed opinions. On balance, owners and reviewers rate the CWC RN Automatic Divers Watch Mk.2 with Date highly for its authentic vintage aesthetic and robust build.

Seiko Prospex Marinemaster 1968 Heritage Diver's Watch

Owners and reviewers widely praise the Seiko Prospex Marinemaster Marinemaster 1968 Heritage Diver's Watch for its exceptional finishing, comparable to Grand Seiko, and refined design, with particular appreciation for its case shape and the 4:00 crown position. The watch is noted for its enjoyable look and feel, and some consider it a significant step up from standard Prospex models, offering premium finishing and a tool-like appearance. The movement Seiko 8L45 is mentioned, along with a 72-hour power reserve and an accuracy of -5/+10 seconds per day. However, some find the price point high, and one reviewer noted the unsigned winding crown as a missed opportunity for a watch in this price range. On balance, owners and reviewers rate the Seiko Prospex Marinemaster Marinemaster 1968 Heritage Diver's Watch highly for its exceptional finishing and refined design at its price point.
