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 C65 Aquitaine Bronze COSC

Owners widely praise the Christopher Ward C65 Aquitaine Bronze COSC for its comfortable wearability, durable case and bezel, and smooth winding action, with one owner finding its case superior to a Tudor's. However, accuracy is a significant concern, with one owner reporting +17 seconds per day. The rubber strap is also noted as lacking refinement, and some suggest design tweaks for greater brand uniqueness. Overall, owners rate the Christopher Ward C65 Aquitaine Bronze COSC highly for its wearability and case finishing, despite accuracy concerns with the Sellita SW330-2 movement.

Hamilton Jazzmaster Seaview Auto Chrono

Owners report that after seven years of daily wear, the Hamilton Jazzmaster Seaview Auto Chrono began gaining approximately 15 seconds per day, requiring a service. Post-service, accuracy improved to +/- 4 seconds per day, and a case replacement was included in a $220 plus tax service cost. One owner finds the Hamilton Jazzmaster Seaview Auto Chrono attractive with its sapphire bezel, clean dial, and polished/brushed finishing. On balance, owners value the watch's aesthetics and finishing, though one owner considers its retail price too high for a quartz model.
