What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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

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.

Sternglas Naos XS

Owners widely praise the Sternglas Naos XS for its simple, awesome design, domed sapphire crystal, and clean hands, with one owner highlighting the beautiful blue mother-of-pearl dial and top-notch build quality on a special edition. It is recommended as a durable, refined daily wear watch for around $270, suitable for casual and formal occasions. However, one owner found the Sternglas Naos XS to have a cheap feel and a face resembling a toy, noting it wears smaller than expected, while another described the automatic movement as a bit noisy. On balance, owners rate the Sternglas Naos XS highly for its refined design and value, with specific praise for the mother-of-pearl dial on special editions.
