Glycine Combat Sub Vintage BronzevsMarathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

The Glycine Combat Sub Vintage Bronze is widely praised for its exceptional value, slim profile, and attractive aesthetic development, with owners frequently highlighting its comfortable wearability and unique design. Its thin case, around 10.4-10.5mm, is a recurring point of admiration, fitting easily under cuffs. The ETA 2824 or SW200 movement is noted as reliable, with one owner reporting accuracy of +1.9 seconds per day. Lume is generally considered strong, comparable to a Seiko SKX007, though one source noted it as subpar. Some owners expressed a desire for ceramic bezel inserts, while others preferred the aluminum for its thinner profile. A few specific criticisms include a non-bronze buckle, the potential for uneven patina from seawater exposure, and inconsistent power reserve not always reaching the advertised 42 hours. Overall, owners rate the Glycine Combat Sub Vintage Bronze highly for its ruggedness and value, making it a compelling choice for a durable diver's watch.

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.
