Sellita
Sellita's day-date automatic caliber, the equivalent of the ETA 2834-2. Adds day and date complications to the proven SW200-1 base architecture while maintaining the same 28,800 vph beat rate and 38-hour power reserve. The additional 0.45mm of height over the SW200-1 accommodates the day display mechanism. A reliable workhorse for brands needing a day-date Swiss automatic at competitive pricing.

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.
