Marathon JDD (Jumbo Day/Date) Anthracite Diver's AutomaticvsLinde Werdelin Spidospeed Titanium – 3D Movement

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.

The Linde Werdelin Spidospeed Titanium – 3D Movement is praised for its comfortable wearability, with reviewers noting its light presence on the wrist despite a 44mm diameter, attributed to forged carbon and titanium construction. The skeletonized dial is described as dynamic, though some find it slightly busy for time-reading. One reviewer appreciated the dial's design and legibility, while another noted improved, though still less attractive, chronograph pushers compared to earlier designs. The watch features a Concepto automatic movement and is limited to 99 or 100 pieces depending on the specific model, with prices around CHF 21,000 or 11,760 euros. On balance, reviewers highlight the Spidospeed Titanium – 3D Movement's innovative material use and comfortable wearability as its strongest attributes.
