Notes on Vintage Watches
Vintage mechanical watches will not keep time with the precision of quartz and do require occasional servicing
Signs of age and patina are natural, and contribute to authenticity and character
At Tempo Prima, we do not pressure test vintage watches. Water resistance is not guaranteed, and we advise keeping vintage watches dry to preserve their condition
