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.
