What people say

Owners + reviewers, side by side

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

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.

Tissot PRX

The Tissot PRX is widely praised for its excellent case and bracelet finishing, offering remarkable value and a luxurious feel that belies its price point. Owners and reviewers consistently highlight its comfortable, thin profile and integrated bracelet design. The dial pattern is noted for its retro, 1980s aesthetic, and the reliable automatic movement contributes to its appeal as a strong contender for a first mechanical watch. However, some owners point out a lack of micro-adjustment on the bracelet clasp, and one reviewer noted issues with quality control on a chronograph model, including a malfunctioning hand and dust on the dial. The sapphire crystal's lack of AR-coating and the shininess of the hour and minute hands are also mentioned as minor drawbacks. On balance, owners and reviewers rate the Tissot PRX highly for its exceptional finishing and value proposition.

From video reviewers

The Powermatic 80 movement's reliability and 80-hour power reserve are consistently praised. The integrated bracelet's susceptibility to scratches is a noted weakness. Reviewers disagreed on whether the Powermatic 80 movement's accuracy significantly surpasses the quartz version.
