AVI-8 Dambuster Operation Catechism 80th Dual Time Chronograph Limited EditionvsYema Flygraf Bi-Compax French Air Force

The AVI-8 Dambuster Operation Catechism 80th Dual Time Chronograph Limited Edition features a dial that is considered neither boring nor overly loud, with case finishing described as acceptable for its price point. Its 43mm meca-quartz design is inspired by Avro Lancaster bomber cockpits and includes a 24-hour subdial with red accents, priced at US$255. The meca-quartz movement provides quartz accuracy and a sweep-second hand, though it is noted as less smooth than an automatic. However, its 51mm lug-to-lug measurement causes it to wear large on wrists up to 17.5cm. Overall, owners find the AVI-8 Dambuster Operation Catechism 80th Dual Time Chronograph Limited Edition to be a well-designed watch for its price, with its primary drawback being its substantial lug-to-lug measurement.

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.
