Seiko Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited EditionvsLongines CONQUEST

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 praise the Longines CONQUEST for its clean, versatile design, excellent build quality, and comfortable wearability, with many highlighting its exceptional value around $1700. Reviewers and owners consistently note the high-quality finishing and the buttery smooth hand-winding feel. Some owners report accuracy figures around -2s/day. Criticisms include a lack of micro-adjustment on the bracelet clasp, a date wheel that may not match the dial, and lume that could be improved, with one reviewer observing that only the black dial version appears to have lumed hands. One owner found the watch underwhelming in person. Overall, owners and reviewers rate the Longines CONQUEST highly for its elegant, everyday sports watch appeal and solid finishing at its price point.
