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.
