What people say

Owners + reviewers, side by side

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

Christopher Ward Twelve X Black Shadow

Owners widely praise the Christopher Ward Twelve X Black Shadow's impressive finishing for its price point and the quality of its bracelet. Some owners, however, feel the $4,865 price is high for the brand, while others argue it offers strong specifications for the money. Reviewers note the skeletonized COSC-certified SH21 movement provides a 120-hour power reserve, but legibility suffers due to the skeletonization and the watch's increased thickness is noticeable. One owner reported sharp edges on bracelet links and unfinished clasp surfaces, leading to a return, despite finding the case and dial appealing. On balance, owners and reviewers rate the Christopher Ward Twelve X Black Shadow highly for its finishing and value, with the skeletonized movement being a key draw.

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.
