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 Guacamole (Gen3)

Owners widely praise the Studio Underd0g Guacamole (Gen3) for its fun, cheerful, and unusual design with great colors, and one owner found its actual wrist presence perfect. Some owners, however, find the dial printing tacky and the overall design looking cheap, while others feel it is a bit pricey for what is offered. The pushers lack crispness, and the crystal is very reflective and domed too much at the edges. One owner expresses concern that it uses a Seagull ST91-B movement, known for a high failure rate. On balance, owners are split on the value proposition of the Studio Underd0g Guacamole (Gen3) at its current price point, with some appreciating its unique aesthetic and others finding the design and movement choices underwhelming.

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.
