What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

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.

Spinnaker Tesei Mille Metri GMT

The Spinnaker Fleuss Midnight Black features a reliable and accurate Japanese TMI NH35 Automatic Movement with 3 Hands and Date. A potential drawback is the watch's relatively low 15 ATM water-resistance rating compared to other watches in its class. Reviewers disagree on the watch's suitability for larger wrists, with one reviewer noting a 43mm diameter and 51mm lug-to-lug fit, while the other mentions a 51mm lug-to-lug measurement.
