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 lightweight titanium construction and anti-reflective sapphire crystal. Reviewers note its comprehensive features including radio-controlled atomic timekeeping, a perpetual calendar, and multiple sub-dials for various time zones and functions. Some owners report readability issues with black hands on certain models, while others find the titanium versions wear comfortably, contrasting with the perceived heft of stainless steel variants. The 45mm stainless steel case is detailed with polished chamfers, brushed finishing, and a bidirectional bezel with a slide rule. Overall, owners and reviewers appreciate the Citizen Promaster Skyhawk A-T for its extensive functionality and durable build at its price point.

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.
