A Note on Vintage Watch Ownership
 
Vintage mechanical watches, while robust and reliable, are not as precise as modern quartz timepieces and may require periodic servicing. Some gentle wear and natural patina should be expected with an original watch of this age. Treated with care, it will continue to be enjoyed for many years to come.
 
At TEMPO PRIMA, we believe vintage watches should not be worn in water, regardless of their original specifications. We do not pressure-test vintage watches and therefore cannot guarantee water resistance. To preserve the longevity and integrity of these timepieces, we strongly recommend keeping them dry and avoiding any exposure to moisture.
