Seiko Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited EditionvsTAG Heuer Formula 1 Chronograph

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 widely appreciate the TAG Heuer Formula 1 Chronograph for its stopwatch function, band expansion, and F1 branding, with some finding it a stunning and worthwhile daily wear that wears smaller than its 43mm case. The double date windows are considered "very cool" by one owner, while another loves the red accents. However, opinions are split on value, with some advising against a quartz movement at this price point, though others appreciate its simplicity and accuracy, with one owner finding the orange quartz model affordable. Durability concerns are raised, including the potential for black coating on pushers and bezel to wear over time and plastic bezels on older models appearing worn. Battery replacement is noted as difficult, and stainless steel bands are described as "garbage." Some owners find the rubber sides unobtainable for repair, and repairs may cost more than the watch is worth. One owner notes the watch has lasted over a decade as a solid, well-made daily watch.
