A Note on Vintage Watches:
Vintage mechanical watches are robust but not as precise as modern quartz timepieces, and periodic servicing is required. Signs of age, including light wear and patina, are to be expected and are part of their character.
At TEMPO PRIMA, we recommend keeping all vintage watches dry. We do not pressure-test for water resistance and therefore cannot guarantee it, regardless of original specifications.
