One reviewer notes the stock rubber strap requires modification for a proper fit. Overall, reviewers rate the Marathon MSAR (Medium Search & Rescue) Diver's Automatic highly for its focus on utility and ruggedness at its price point.

Seiko Coutura

Seiko Coutura owners widely praise its wear-resistant metal treatments, with one reporting minimal scratches after six years. The watch is also lauded for its solar and perpetual calendar features, offering a "set it and forget it" experience with 100m water resistance. Owners appreciate its weight and captivating appearance, with one purchasing it for $410.88. The aesthetic, featuring contrasting gold indices and hands against a black dial, is considered appealing by some, particularly those who enjoy its unique and fun design. However, opinions on styling are divided, with some finding the dial too busy and gaudy, and others describing the line as large or sitting too high. The proprietary bracelet is also noted as a downside by some owners. One owner reports the solar power reserve can be problematic if not exposed to light regularly, while another calls their kinetic perpetual a beautiful keeper with a 4-year reserve.
