What people say

Owners + reviewers, side by side

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

Oris Great Barrier Reef Limited Edition IV

The Oris Great Barrier Reef Limited Edition IV's 43.55mm case is surprisingly wearable on a 7-inch wrist due to its new design. Owners report the Oris Great Barrier Reef III, a 45mm watch, is massive and nearly 20mm thick. Overall, owners find the Oris Great Barrier Reef Limited Edition IV wearable despite its size, citing its new design as a key factor.

From video reviewers

The striking turquoise-to-navy gradient dial is a notable feature. The 43.5mm stainless steel case is noted for its ergonomic fit.

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.
