What people say

Owners + reviewers, side by side

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

Tornek-Rayville TR-660 Sapphire Non-date

Owners widely praise the Tornek-Rayville TR-660 for its quality, good timekeeping, and suitability as a military diver reissue. The 40mm bead-blasted 316L stainless steel case, sapphire bezel inlay, and Arclite Super LumiNova are noted features, powered by a Japanese TMI NH38 automatic movement and water-resistant to 20 ATMs. Some owners suggest alternatives due to availability issues with the small-batch releases. Overall, owners rate the Tornek-Rayville TR-660 highly for its faithful reissue design and quality build at its price point.

Tudor Black Bay 58 925

The Tudor Black Bay 58 925 is praised for its unique taupe dial and bezel, and COSC-certified movement. Owners widely report the silver case scratches and dings more easily than steel, and some experience tarnishing despite anti-tarnishing claims, though it can be cleaned with an eraser or silver cloth. While some find the leather strap uncomfortable due to weight imbalance, others consider it suitable. The dial can appear washed out in certain lighting, and one owner notes the long springbar can scratch the case if it pops out. On balance, owners and reviewers appreciate the Tudor Black Bay 58 925 for its unique silver case and taupe dial, despite concerns about scratching and tarnishing.
