What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Seiko Prospex SPEEDTIMER

Owners widely praise the Seiko Prospex SPEEDTIMER for its unique dial colors and vintage-inspired design, with many appreciating its compact 39mm case size and 100m or 200m water resistance. Reviewers and owners note the V192 solar movement’s power reserve indicator and its reliability, though some owners express a preference for automatic movements. One owner finds the $700 price for a solar quartz model expensive, while another criticizes the €860 price point and desires a thinner case and a bracelet with quick-release or micro-adjustment. On balance, owners and reviewers appreciate the Seiko Prospex SPEEDTIMER for its distinctive aesthetic and versatile wearability, despite some reservations about its price and case thickness.

Sternglas Tachymeter

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.
