Owning a Vintage Watch:
 
Mechanical watches do not keep perfect time like a battery-powered watch. In addition, they do require service occasionally.
Since these pieces are vintage or pre-owned, please expect wear and patina from past usage and age.
If dropped, mishandled or otherwise abused, the movement or other parts of the watch can be damaged. Please handle with care. We hope you enjoy this item and wear it in good health for years to come!
