What people say

Owners + reviewers, side by side

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

CWC 1983 RN Divers Quartz Re-Issue Watch

Owners widely praise the CWC 1983 RN Divers Quartz Re-Issue Watch for its historically accurate reproduction, thin profile for a 300m diver, and a second hand that aligns well with indices. Reviewers note its reasonable size on smaller wrists, original dial layout with markers touching the chapter ring, and a broader minute hand. However, criticism is directed at the fixed 20mm bars necessitating specific strap types and the mismatched lume colors between hands and hour markers, with some finding the convex lume on the markers overly shiny. Overall, owners rate the CWC 1983 RN Divers Quartz Re-Issue Watch highly for its accurate vintage aesthetic and wearability.

Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation

The Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation is noted for its refined, slimmed-down 39.5mm stainless steel case with a "super hard" coating and a box-shaped sapphire crystal. It offers 200 meters of water resistance and is powered by the slim Caliber 6L37 automatic movement, which has a 46-hour power reserve and an accuracy rating of -10/+15 seconds per day. Reviewers highlight its wearability and functionality as a dive watch, with one noting it as Seiko's thinnest diver ever at 12.3mm. However, concerns are raised about Seiko's continued reliance on the 62MAS design, with one reviewer wishing the Marinemaster remained a separate line, and the bracelet's end-links appearing mismatched in initial images. Its price of A$4,650 is considered high given its specifications compared to competitors.
