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 Skyhawk A-T

The Citizen Promaster Skyhawk A-T is praised for its comprehensive feature set, including radio-controlled atomic timekeeping, a perpetual calendar, and a second time zone subdial. Reviewers note the titanium models offer good wearability, though one owner found the watch felt like a boat anchor. The stainless steel versions feature polished chamfers, brushed finishing, and a bidirectional bezel with a slide rule. Some models, particularly those with black hands against a black dial, have been criticized for poor readability, while others offer semi-skeletonized white sword hands and stencil numerals for improved legibility. On balance, owners and reviewers appreciate the Citizen Promaster Skyhawk A-T's extensive functionality and build, though legibility can be a concern on certain dial configurations.

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.
