Feels like a bigger size on the wrist because of the chunky case shape. Powered by a Valjoux 7733 Swiss manual-wind mechanical movement. 17-jewels. Silver dial with blue sub dials. Tachymeter on the inner bezel. A classic Swiss timepiece! Asking $555 USD OBO including shipping within North America. Great international rates available too.
