Fears Onyx (collective Horology)vsYema Flygraf Bi-Compax French Air Force

Owners widely praise the Fears Onyx (collective Horology) for its exquisite glossy black onyx dial, which displays microscopic striations under magnification. Reviewers note its thin case, under 10.5mm, and a balanced sporty-dressy aesthetic. Water resistance is rated at 150m by one source and 100m by another, and the bracelet features on-the-fly micro-adjustment. Some owners find the 39.5mm diameter slightly large for the style, and one source suggests it doesn't represent top value, though it remains competitive. Overall, owners rate the Fears Onyx highly for its unique stone dial and wearability.

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.
