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 A-T

Owners widely praise the Citizen Promaster Eco-Drive for its value, reliability, and maintenance-free operation. Reviewers note the Citizen Promaster Air Automatic GMT is a large 44.5mm watch with a well-proportioned case and balanced dial, powered by an in-house automatic GMT movement. Concerns are raised about the unframed date window and uninspired case design on the GMT. Some owners find certain models, like the 36mm Eco-Drive, to be very small. The Promaster Air Automatic GMT is priced at $1,125 USD. On balance, owners and reviewers highlight the Promaster's strong value and reliability as its primary strengths.

Fortis Flieger F-43 Bicompax

Owners widely praise the Fortis Original for its tool-watch aesthetic, legibility, and robust construction, with many noting excellent lume that lasts all night and precise day/date changes at midnight. The brushed stainless steel case is well-finished, and the 38mm size is considered comfortable and well-weighted despite being smaller than modern watches. Accuracy figures range from +2 seconds/day to +8 seconds/day, and some owners compare Fortis quality favorably to Omega. However, some users find the MSRP too high compared to brands like Sinn and Damasko, and one owner reported internal parts dislodging from a limited edition model. Concerns have also been raised about stripped lug screws on B-42 models and potential parts shortages due to past bankruptcy protection filings. Overall, owners rate the Fortis Original highly for its durable construction and tool-watch functionality at a competitive price point.
