What people say

Owners + reviewers, side by side

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

Citizen Promaster Air GMT

The Citizen Promaster Air GMT is widely praised for its impressive in-house Cal. 9054 automatic GMT movement, excellent case fit and finish, and a high-quality bracelet for its price point. Reviewers highlight its striking anti-reflective domed sapphire crystal, legible dial with large numerals, and long-lasting lume. However, its 44.5mm dimensions are considered unfashionably large, and the case design is described as uninspired. The independent hour jumping is noted as mushy and unable to be set backward, while the unframed 3 o'clock date window and minute track on the rehaut being obscured by case shadows are also flagged as drawbacks. The watch is priced at $1,125 USD and features 200m water resistance and a 50-hour power reserve. On balance, reviewers commend the Citizen Promaster Air GMT for its strong movement and legibility at an affordable price, despite reservations about its case size and some functional aspects of the GMT hand.

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.
