Marathon GPQ-D (Officer's Quartz with Date) Field Watch

Marathon GPQ-D (Officer's Quartz with Date) Field Watch owners praise its tritium tubes, Mil-spec designation, and scratch-resistant case finish, with some finding the 36mm size practical for field use. However, some owners criticize its perceived overpriced nature, thick case, and squared-off lugs, while others point to the composite case material, 30m water resistance, and unbranded movement as drawbacks. On balance, owners are divided on the Marathon GPQ-D (Officer's Quartz with Date) Field Watch, with opinions split on its value and design features.

Seiko Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited Edition

The Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited Edition is praised for its retro design, balanced 42mm case, good finishing, and sapphire crystal. It is powered by the calibre 8R48, featuring a column wheel and vertical clutch, and offers 100m water resistance. Some find its 45-hour power reserve short compared to modern alternatives, and the date window placement is a point of discussion. The solar-powered variant is noted for its compact proportions and character, though some desire thinner cases and improved bracelet micro-adjustment. Overall, owners and reviewers appreciate the SPEEDTIMER's vintage-inspired aesthetics and solid build, with critiques focusing on power reserve and minor functional details.
