A few things you might still wonder
How does an automatic watch work?
How does an automatic watch work?
A rotor turns as your wrist moves, winding a spring that stores energy. That stored energy powers the movement, so there is no battery to replace.
What if I haven’t worn it for a few days?
What if I haven’t worn it for a few days?
When the power reserve runs down, the watch stops. Follow its winding instructions, reset the time, and wear it again.
How should I care for the leather strap?
How should I care for the leather strap?
Keep leather away from prolonged moisture and direct heat. Wipe it gently with a soft cloth and let it dry naturally if damp.
Time well worn
The Calibre Behind Tachymeter 2.0 dark blue
The Seiko TMI VK63 gives Tachymeter 2.0 its measured pulse. Its timing architecture is designed for dependable daily use and a clear, practical display. Useful functions include date, stopwatch, tachymeter scale, small seconds and 24-hour display. Chosen for clarity and reliable daily use, the mechanism supports the watch without distracting from its design.
Modena black with Easy Comfort
The strap completes the design of Tachymeter 2.0. Made from leather, it follows the wrist with a balanced feel and keeps the composition coherent from case to clasp. The material will soften with wear and gain a more personal character over time.
