How do I wind a mechanical watch?

Wind the crown clockwise between your thumb and forefinger until you feel gentle resistance. Stop immediately to avoid over-tensioning the mainspring. For automatic models, normal wrist movement powers the internal rotor, though manual winding can jumpstart the reserve if the watch has stopped entirely.

Are these watches waterproof?

Period mechanical watches lack modern sealing technology and gasket systems. Contact with water or moisture should be avoided entirely. Even pieces marked as hermetic or military use older sealing methods that degrade over decades, leaving the internal movement vulnerable to rust.

How do I date a vintage watch?

Dating relies on stylistic cues such as dial typography, case geometry, and movement serial numbers where available. Mid-century pieces often feature clean minimalist markers, whilst earlier decades lean toward ornate Art Deco geometry. Associated hallmarks on precious metal cases also provide solid manufacturing periods to anchor the production timeframe.

How accurate are mechanical wristwatches?

Vintage mechanical movements vary in daily timekeeping variance compared to quartz technology. Gaining or losing a minute per day remains entirely normal for unserviced or vintage calibres. Regular servicing by a watchmaker helps restore optimal regulation and timing consistency across the gear train.
