What people say

Owners + reviewers, side by side

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

Synchron 70s Military

Owners praise the Synchron 70s Military for its 70s design, robust finishes, and wearability, with one owner finding it comfortable for smaller wrists. The watch is noted for its legible dial with orange hands and contrasting indices, though one commenter questioned legibility due to numerous indices. The bezel action is tight and quality, and the dial printing is excellent. Some owners report crown wobble at full extension and a need to reseat the screw-down crown initially. Overall, owners and reviewers consider the Synchron 70s Military a well-executed homage that captures vintage quality, with its design and finishing being key strengths.

Synchron Poseidon

Owners widely praise the Synchron Poseidon for its vintage-inspired diver aesthetics, easy-to-read dial, and precise, grippy bezel. The La Joux-Perret G100 movement is consistently noted as a strong point, with owners reporting good timekeeping, with one seeing it lose about 4 seconds per day, and a 68-hour power reserve. Some find the design busy or the branding confusing, while others appreciate its unique look, comparing it favorably to other military divers. The watch is considered good value, with one reviewer noting its $999 pre-order price and another praising the reassuring crown action as superior to watches at double the cost. On balance, owners and reviewers rate the Synchron Poseidon highly for its vintage charm, robust movement, and excellent value proposition.
