Seiko Presage Sharp Edged SeriesvsYema Flygraf Bi-Compax French Air Force

The Seiko Presage Sharp Edged Series is widely lauded for its sharp, angular case design and the intricate finishing of its dials, often featuring traditional Japanese motifs like the Asanoha pattern. Owners and reviewers consistently highlight the beautiful interplay of polished and hairline finishes on the case and bracelet, the use of sapphire crystals, and a robust 100m water resistance. The collection is powered by reliable in-house automatic movements, with many models featuring the 6R35 movement offering a 70-hour power reserve. Some specific models are noted for their refined finishing and updated case facets, while the 24-hour sub-dial on certain variants is considered a niche complication. Overall, owners and reviewers rate the Seiko Presage Sharp Edged Series highly for its striking design and quality finishing 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.
