Seiko Prospex Speedtimer Seiko Brand 100th Anniversary Speedtimer Limited Edition

The Seiko Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited Edition is praised for its retro design and good finishing within a balanced 42mm case. Reviewers note a 100m water resistance and sapphire crystal. One review flags the 45-hour power reserve as short compared to modern Swiss competitors, and the date window at 4:30 is a point of debate. Another review suggests a desire for a thinner case, quick-release strap mechanisms, and micro-adjustment on the bracelet, while also perceiving the watch as costly. On balance, reviewers appreciate the vintage-inspired design and finishing but note trade-offs in power reserve and bracelet features, with some finding the price point high.
