Sternglas TachymetervsYema Flygraf Bi-Compax French Air Force

The Sternglas Tachymeter is praised for its sporty chronograph design and wrist presence, offering character without being an overt tool watch. Reviewers note it as an improvement over its predecessor, featuring an upscale design with a colored aluminum bezel insert and more colorful dial options. It utilizes the Seiko VK63 meca-quartz movement, is accurate to ±20 seconds per month, and boasts a three-year battery life, all at a competitive price of €389. The Sternglas Tachymeter is considered good value for its design, functionality, and small-brand cachet, offering a charming youthfulness. One reviewer noted that the "orange" on one model appeared yellow, and suggested a tachymeter scale extending to 200 instead of 500 would be more useful. Overall, owners and reviewers rate the Sternglas Tachymeter highly for its value and appealing, youthful chronograph design.

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.
