NOMOS Glashütte Lambda 39vsYema Flygraf Bi-Compax French Air Force

Owners and reviewers widely praise the NOMOS Glashütte Lambda 39 for its spare clarity, minimalist purity, and Bauhaus dial design with excellent legibility. The in-house hand-wound caliber DUW 1001 is noted for its Glashütte finishing, including a three-quarter plate, hand beveling, and engraved balance cock, with an 84-hour power reserve. Some owners consider the full gold case and giant power reserve display well worth the price for its fine horology and minimalist elegance, while others find the oversized power reserve display and dial design clash with the main hands, and some dislike the lettering on the power reserve indicator. The high price point for gold models, around $18,000-$20,000, is considered steep by some, a significant departure from NOMOS's typical offerings.

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.
