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.

Fortis Marinemaster M-40

Owners praise the Fortis Amber Orange for its gorgeous appearance and strong wrist presence, noting its crazy lume and 70-hour power reserve. The Doxa SUB 300T, described as having a superb, eccentric design with a highly legible dial and functional no-decompression bezel, uses an ETA 2824-2 movement. However, the SUB 300T's 42.5mm case wears large and its 14mm thickness is not ideal for dress shirts, though it boasts 1,200m water resistance. On balance, owners appreciate the Fortis Amber Orange for its striking aesthetics and impressive lume.
