Instructions
Ideal Storage Conditions
Store your vintage watch out of direct sunlight, which will adversely affect the watch's outer varnish.
Store your vintage watch out of humidity, which can damage the movement of the watch.
Keep vintage watches away from magnets. Strong magnetic fields may affect the accuracy of your watch since some vintage watches were made with iron-based components.
Watch Storage
Store your vintage watch in the original watch box it came in and keep the box in a drawer or cabinet. This will protect the watch. However, if you have many vintage watches, this might not be the best option for you.
Store your watch in a cigar humidor box. This type of box has a constant humidity and temperature, so you can control the settings under which your watch will be stored.
Store your vintage watch in a quarter or half-ton safe. Make sure the safe is not a fire safe, as these types of safes are fire-resistant because their walls are made of a moist cement-like filling which promotes moisture buildup within the safe. Even regular safes can require some de-humidifying, such as electric heaters or low wattage bulbs.
