How do I wind a manual watch?

Turn the crown clockwise between your thumb and forefinger until you feel gentle resistance. Stop immediately once 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 throughout its reserve.

How often need they be serviced?

Mechanical watches require professional servicing every few years to replenish internal oils and inspect wear on gear teeth. A clean movement prevents friction from damaging delicate pivots over time. Regular maintenance ensures the manual wind mechanism operates smoothly and preserves the longevity of vintage components.

Can I swim with these watches?

Vintage timepieces lack modern waterproof seals and gasket systems found in contemporary dive watches. Moisture easily penetrates through the crown, crystal, and case back, rusting steel components. Keep these watches away from water, heavy rain, and high humidity to protect the delicate dial and movement.

How do I date these watches?

Dating relies on internal movement serial numbers cross-referenced against production ledgers, alongside case style and dial typography. Specific design cues such as handset shapes and logo styles also point to particular eras. Reference numbers stamped inside the case back provide further confirmation of the exact production period.
