Glycine Airman Contemporary GMTvsMarathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

Some owners find the GMT hand's similarity to the minute hand frustrating, and the ETA movement can exhibit a misaligned GMT hand. One owner notes the lume pips are weaker than the hands, while another highlights its 200m water resistance and considered it a great beater. Overall, owners rate the Glycine Airman Contemporary GMT highly for its unique functionality and value proposition.

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.
