What people say

Owners + reviewers, side by side

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

Studio Underd0g Mint Choc Chip (Gen3)

Owners and reviewers praise the Studio Underd0g Mint Choc Chip (Gen3) for its unique, visually striking design, featuring an asymmetrical dial, textured two-tone finish, orange chrono hand tips, and chocolate chip hour markers, all housed in a comfortable 38.5mm case with a hand-winding SeaGull ST-1901 movement and a goat-skin strap. Some owners, however, find the watch overpriced for its movement and dial quality, and a few feel it appears toy-like on larger wrists. Overall, owners and reviewers value the Studio Underd0g Mint Choc Chip (Gen3) for its distinctive aesthetic and comfortable wear, despite some reservations about price and perceived scale.

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.
