Marathon JDD (Jumbo Day/Date) Anthracite Diver's AutomaticvsSugess Seakors Tourbillon SE8007

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 Sugess Seakors Tourbillon for its attractive dial and case finishing, along with the value offered by its functional flying tourbillon. One owner reports the Seagull ST8007 movement is reliable, running at -2s/day or +5s/day. However, the 24-hour complication is considered questionable, and some dust and oil are visible under magnification. With 5ATM water resistance and no lume, it is not suited for demanding activities. On balance, owners rate the Sugess Seakors Tourbillon highly for its impressive tourbillon complication and design at its price point.
