Marathon JDD (Jumbo Day/Date) Anthracite Diver's AutomaticvsRedux Zero-Hour

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.

Owners widely praise the Redux Courg Type 39MM for its robust, no-nonsense design and good overall quality, with a reliable Seiko NH53A movement keeping time well. The titanium case and crystal have shown scratch resistance, and the bezel action is described as tight by some. Reviewers note the proprietary RDXB1 or blue lume glows brilliantly, though briefly. Some owners flag the crown stem as flimsy and the unidirectional bezel as having some play. Overall, owners rate the Redux Courg Type 39MM highly for its functional tool-watch design and durable titanium construction.
