Marathon JDD (Jumbo Day/Date) Anthracite Diver's AutomaticvsZelos Hammerhead 2 1000m Bronze 'Forged Carbon' ETA2892

The Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic is widely praised as a tough, underrated tool watch with excellent legibility due to its tritium lume. Owners appreciate its robust build and lifestyle appeal, though its 46mm size is a common point of criticism, with some finding it heavy and top-heavy. One reviewer noted the white day/date discs clash with the anthracite dial, and an owner observed the watch running about 10 seconds fast over three days. On balance, owners and reviewers rate the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic highly for its robust build and excellent legibility as a tool watch, despite its substantial size.

Owners and reviewers speak warmly of the Zelos Hammerhead 2 1000m Bronze 'Forged Carbon' ETA2892, with one owner saying it looks unlike anything else in their collection and that they are "not happier" with it, calling it exactly what they hoped for from a microbrand. Its warm bronze case and split polished/satin finish get praise, and owners single out the lume as hard to match for the price. The main criticisms are its thickness, which a review says would look more striking at 3-4mm thinner, and uneven minute marker spacing that one owner finds annoying but accepts as a compromise. Overall, owners and reviewers rate the Hammerhead well for its distinctive look and value, with the bulk of its drawbacks being a matter of design preference.
