Hamilton Jazzmaster QuartzvsYema Flygraf Bi-Compax French Air Force

The Hamilton Jazzmaster Quartz is praised for its solid crown feel, avoiding accidental hacking, and its comfortable proportions with a mainstream aesthetic. Reviewers highlight the case finishing, which features horizontal and vertical brushing alongside polished chamfers. The quartz movement ensures accurate timekeeping, though it is not considered a standout feature. This Hamilton Jazzmaster Quartz is priced at CHF 395. Overall, owners and reviewers rate the Hamilton Jazzmaster Quartz highly for its refined case finishing and reliable timekeeping at its price point.

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.
