This is a vintage/pre-owned mechanical watch. Due to the age and nature of vintage timepieces, minor signs of wear may be present. Mechanical watches can require periodic servicing, and timekeeping accuracy and power reserve may vary depending on the watch’s age, condition and previous service history.
The 7S26C movement does not feature manual hand-winding or hacking seconds, which is normal for this caliber.
