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 (Ti)

The Christopher Ward Twelve X (Ti) is praised for its exceptionally finished, lightweight titanium case and COSC-certified, skeletonized SH21 movement offering a 120-hour power reserve. Reviewers note its comfortable wearability due to the rounded case shape, despite a 12.3mm thickness, and highlight the micro-adjust clasp. Legibility is considered good for a skeletonized watch, though reduced compared to standard dials. One reviewer points out that the case chamfers may be prone to dings and the movement finishing does not reach higher-end standards. Overall, reviewers rate the Christopher Ward Twelve X (Ti) highly for its impressive case finishing and the value of its COSC-certified, in-house skeletonized movement.

Seiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's Watch

The Seiko Prospex Marinemaster 1965 Heritage Diver's Watch is praised for its faithful re-creation of the 62MAS design, with reviewers noting improved wearability due to smaller case sizes (38mm to 40mm) and updated bracelets. Specific models feature a stainless steel case with super-hard coating, ceramic bezel, and a tool-free extension system on the bracelet. Accuracy figures vary, with one model rated at -5/+10 seconds per day and another at -10/+15 seconds per day, powered by movements like the Caliber 8L45 or 6L37 offering 72-hour or 46-hour power reserves respectively. Some reviewers point out drawbacks such as an unsigned winding crown, a lack of tool-free micro-adjust on the clasp for certain models, and a secondary GMT function on one variant. The price point, ranging from $2,800 to $3,600, is considered high by some, especially when compared to other Seiko or Grand Seiko offerings.
