What people say

Owners + reviewers, side by side

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

CWC 1987 SBS Quartz Diver Re-Issue Watch

Owners widely report the CWC 1987 SBS Quartz Diver Re-Issue Watch as very hard-wearing, with good seconds hand alignment and perfect bezel alignment with crisp action. The lume is described as pretty good despite fauxtina, and the watch gains approximately 3 seconds per month. Some owners consider the CWC 1987 SBS Quartz Diver Re-Issue Watch overpriced, while others appreciate its bombproof, toolish design and military heritage.

Seiko Astron

Owners widely praise the Seiko Astron for its spectacular technology, self-sufficiency, and grab-and-go convenience, with one owner calling it the best watch they have ever had. Reviewers and owners highlight the detailed and well-managed dials, often with "Grand Seiko-esque" precision, and appreciate the comfortable, lightweight titanium construction. The solar-powered quartz movement with GPS time sync is a significant draw, offering accurate timekeeping. However, the price point of around €2250-€2400 is frequently cited as high for a quartz watch. Some owners note manual DST implementation, dependence on outdoor conditions or radio tower proximity for GPS sync, and sparse lume. One owner experienced the minute hand sitting slightly off and found the recessed buttons difficult to operate. Accuracy figures vary, with some reporting +/- 15 seconds per month without GPS, while others note autonomous quartz movement accuracy of up to 1/2 second per day.
