What is a bumper automatic movement?

A bumper automatic is an early self-winding mechanical system where the weighted rotor swings through a partial arc, hitting springs that bounce it back. Wearers can feel a gentle nudge on their wrist as the mechanism winds itself throughout the day.

How do I identify the production year?

Production dates are often estimated using movement serial numbers or specific case references recorded by the manufacturer during manufacture. Matching the internal calibre number with historical ledgers provides a reliable date of origin.

Are these watches suitable for daily wear?

Many vintage models were built for everyday utility, particularly robust stainless steel Seamaster lines designed for regular use. Care must be taken with older water resistance seals and non-waterproof dress pieces, keeping them away from moisture.

What distinguishes a Seamaster from a Geneve?

The Seamaster line historically denoted sports and water-resistant designs, featuring sturdier case constructions and often automatic calibres. Geneve models generally represent dressier, elegant everyday timepieces produced in large quantities during the mid-century period.
