Marathon Steel Navigator SSNAV-D AutovsStudio Underd0g Guacamole (Gen3)

The Marathon Steel Navigator SSNAV-D Auto is praised for its durable construction, featuring a sandblasted steel case with improved lugs, a bi-directional bezel with excellent action, and 100m water resistance. Owners appreciate the constant visibility provided by self-illuminating tritium gas tubes and the precision of its ETA F06.412 quartz movement, which offers accuracy to about 10 seconds per year. The watch includes a GMT bezel for dual timekeeping and a synthetic sapphire crystal. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Auto highly for its robust tool-watch design and reliable tritium illumination.

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.
