Tissot PR 100vsYema Flygraf Bi-Compax French Air Force

Owners widely praise the Tissot PR 100 for its excellent value, with specific mentions of its sapphire crystal, 100m water resistance, and the 80-hour power reserve of its Powermatic 80 movement. Reviewers and owners consistently highlight its pleasing winding action and strong lume. Accuracy figures for the Powermatic 80 COSC variants are reported as -2 seconds per day or +/- 1-2 seconds per day. Some owners note that the crystal attracts fingerprints and that the black finish on some bracelets can wear off after extended daily use. A single owner of a quartz model experienced a recurring issue where the watch stopped for periods weekly, which was not resolved by a battery replacement. Overall, owners and reviewers rate the Tissot PR 100 highly for its exceptional value and robust features, particularly its durable construction and reliable movements.

Owners widely praise the Yema Flygraf Bi-Compax French Air Force for its attractive, toolish aesthetic and excellent quality for the price, noting the legible Type A dial and 40mm titanium case. However, the acrylic crystal scratches easily, and the titanium case is prone to marking. The mecha-quartz movement's chrono timer sweeps rather than ticks, and one owner questions the purpose of the oversized crown. The in-house Yema 2000 movement is accurate at +/- 10 seconds per day but has a 42-hour power reserve, and some owners express concerns regarding Yema's past quality control and customer service. On balance, owners rate the Yema Flygraf Bi-Compax French Air Force highly for its attractive design and value, despite concerns about material durability and brand service history.
