What people say

Owners + reviewers, side by side

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

Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

Owners widely praise the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic as a tough, underrated tool watch with lifestyle appeal, highlighting its robust build and tritium lume for excellent legibility. However, its 46mm size is a common criticism, with some finding it heavy and top-heavy, and the OEM rubber strap stiff. One owner noted the watch runs about 10 seconds fast after three days, and the ETA 2836-2 movement offers approximately two days of power reserve. On balance, owners and reviewers rate the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic highly for its robust tool-watch build and legibility, despite its substantial size.

Studio Underd0g Watermelon (Gen3)

Owners widely praise the Studio Underd0g Watermelon (Gen3) for its fun, entrepreneurial, and affordable nature, with a design described as "Bauhaus meets Bugs Bunny." However, some find its colors a love-it-or-hate-it feature and others perceive the overall quality and finishing as a tier below comparable watches. Accuracy figures are not specified, but one owner found the watch too thick for their taste. The chronograph function has been noted as potentially sticky or jumpy. On balance, owners are divided on the Studio Underd0g Watermelon (Gen3), with opinions split between its unique design and perceived value for money.
