How do I wind a manual watch?

Gently rotate the crown clockwise between your thumb and forefinger until you feel slight resistance. Stop immediately once the tension increases to avoid damaging the internal mainspring. Wind the watch at roughly the same time each day to maintain consistent tension and accurate timekeeping across the movement.

Are these watches water resistant?

Vintage pieces generally lack modern rubber seals and screw-down components designed for aquatic environments. Even models labelled for water resistance should be kept away from moisture. Avoid swimming, showering, or washing hands while wearing a vintage leather timepiece to protect the delicate movement and prevent strap degradation.

How do I care for leather straps?

Keep the leather dry and away from direct sunlight and excessive sweat to prevent cracking and discoloration. Clean the surface gently with a dry or slightly damp cloth when necessary. Allow the leather to rest occasionally by alternating between different straps if you wear the watch daily.

How do I determine the decade?

Examine the stylistic cues of the dial, case geometry, and typography, which reflect the distinct design languages of the 1930s through the 1960s. Art Deco influences mark earlier pieces, while cleaner geometric lines define later decades. Opening the case back often reveals a movement serial number that can be cross-referenced with manufacturer records for precise dating.
