What people say

Owners + reviewers, side by side

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

Marathon OSAR-D (Original SAR with Date) Automatic 46mm

The Marathon OSAR-D (Original SAR with Date) Automatic 46mm is widely regarded as a rugged and legible timepiece, featuring a familiar geometric dial with MaraGlo lume and a white dial with applied hour markers that enhance legibility. Owners and reviewers note its 300-meter water resistance and the reliable Swiss-made Sellita SW200-1 automatic movement with improved shock protection. The watch is described as large, thick, and heavy, with some owners finding it comfortable on the wrist while others note its substantial presence, particularly at a table. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 46mm for its rugged build and excellent legibility.

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.
