Glycine Combat Sub Chronograph SportvsMarathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

Owners widely praise the Glycine Combat Sub Chronograph Sport for its exceptional value as a Swiss automatic diver, highlighting its refined finishing, thin profile at around 10.4-10.8mm, and accurate movements. The watch is noted for its comfortable wearability, with downward-curving lugs on the 42mm case making it wear smaller than its dimensions suggest, and its unique aesthetic is appreciated for avoiding homage designs. Some owners dislike the "COMBAT" text on the dial and find the original strap or bracelet to be lacking, though it is considered a versatile "strap monster." The lume is described as sub-par by one owner, and another noted an inconsistent power reserve. There is a design critique regarding the date window placement, with one owner calling it a significant flaw while another finds it acceptable due to its alignment with the crown.

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.
