Seiko Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited EditionvsSternglas Tachymeter

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.

The Sternglas Tachymeter is praised for its sporty chronograph design and wrist presence, offering character without being an overt tool watch. Reviewers note it as an improvement over its predecessor, featuring an upscale design with a colored aluminum bezel insert and more colorful dial options. It utilizes the Seiko VK63 meca-quartz movement, is accurate to ±20 seconds per month, and boasts a three-year battery life, all at a competitive price of €389. The Sternglas Tachymeter is considered good value for its design, functionality, and small-brand cachet, offering a charming youthfulness. One reviewer noted that the "orange" on one model appeared yellow, and suggested a tachymeter scale extending to 200 instead of 500 would be more useful. Overall, owners and reviewers rate the Sternglas Tachymeter highly for its value and appealing, youthful chronograph design.
