Seiko Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited EditionvsTissot PR516

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.

Owners and reviewers widely praise the Tissot PR516 for its athletic 1970s charisma, vintage-inspired dial design, and thoughtful finishing. The manual-wind chronograph variant is noted for its robust case and impressive A05.291 movement with a 68-hour power reserve, while the automatic Powermatic 80 variant offers an 80-hour power reserve in a 38mm steel case at an accessible price. However, several sources flag the bracelet clasp as a letdown, describing it as a folded steel or stamped design that does not match the case quality. Some owners find the dial bland or wish the bezel looked different, and one reviewer notes the 14mm thickness of the chronograph can be noticeable. The Powermatic 80 variant's fixed bezel is criticized by one owner as a departure from dive watch principles. On balance, owners and reviewers rate the Tissot PR516 highly for its strong value and retro-inspired design, with the chronograph movement and accessible pricing being key draws.
