What people say

Owners + reviewers, side by side

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

Bremont S500

Owners widely praise the Bremont S500's excellent Super-LumiNova lume and refined finishing, with many finding its 43mm case comfortable and versatile on the wrist due to short lugs and an offset crown. Reviewers and owners alike note its handsome, rugged design and improved dial legibility for diving. However, some find the 16mm to 16.5mm thickness less practical for daily wear, and one reviewer flags legibility issues with the dark dial and hands. Concerns are raised by one source regarding the three-piece case construction's long-term water resistance for actual diving, while another criticizes the understated bezel markings and the second hand's visibility in low light. The COSC-certified ETA 2836-2 movement provides a 38-hour power reserve. On balance, owners and reviewers rate the Bremont S500 highly for its distinctive design and robust build quality, despite some reservations about its thickness and specific legibility elements.

Longines PRIMALUNA

Owners widely praise the Longines PRIMALUNA for its attractive style and understated 26.5mm size, with some preferring the automatic for its craftsmanship and heirloom quality. The redesigned 34mm model features an automatic movement, date complication, and polished case design, available in steel or bi-metal with various dial and strap options. Accuracy averages a loss of 1.3 seconds per day across six positions, running 3-4 seconds slower on the wrist, which is within COSC standards. Prices range from EUR 2,850 to EUR 6,600. Overall, owners rate the Longines PRIMALUNA highly for its appealing design and reliable automatic movement.
