AVI-8 Dambuster Operation Catechism 80th Dual Time Chronograph Limited EditionvsYema Diver

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.

One owner reported a water ingress issue on their Yema Diver the first time it got wet in a lake, despite rinsing and inspecting the watch and bezel. Another owner notes this manual wind Yema Diver has a cool patina but is unlikely to be waterproof or gain value. Overall, owners view the Yema Diver as a fun second watch rather than an investment.
