Sinn 717vsMarathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

The Sinn 717 is widely praised for its legible, cockpit-instrument-inspired dial and the functional SZ01 movement with central chronograph minute and second hands. Owners appreciate its solid winding action, crisp button feel, and accurate date changes. Despite its 45mm diameter, the Sinn 717 wears well due to its short lug-to-lug distance and comfortable strap options, and its TEGIMENT-treated black PVD case offers significant scratch resistance. Reviewers highlight its robust build quality and 200m water resistance, noting the innovative bezel sealing. Some community members criticize the blacked-out case aesthetic, and one owner finds the bezel action stiff, which they also see as a positive for preventing accidental turns. On balance, owners and reviewers rate the Sinn 717 highly for its unique legibility, robust construction, and comfortable wearability at its price point.

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.
