What people say

Owners + reviewers, side by side

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

Bremont Supermarine Chrono

The Bremont Supermarine Chrono's black dial and understated bezel markings allow it to transition effectively from rugged use to evening events. On balance, owners and reviewers find the Bremont Supermarine Chrono to be a handsome and functional watch, with its versatile dial design being a key strength.

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.
