Wristwatches

Wristwatches range from everyday timepieces to sought-after collectibles. Brand, model, reference number, movement, age, originality and condition are key factors in identification and assessment.

How to identify a wristwatch

Begin with the dial and case-back markings. A reference may be visible externally or inside the case back; mechanical movements may carry a maker and calibre number. Record case material, diameter excluding the crown, crystal, bracelet or strap and serial numbers. Do not open a case without suitable tools and experience.

Mechanical, automatic or quartz

A hand-wound watch is wound through the crown, an automatic uses a rotor, and a quartz watch is normally battery-powered. Moving hands do not prove accurate timekeeping. State known service history, timekeeping and functions.

Condition and originality

Inspect the dial, hands, crystal, crown and case. Heavy polishing can soften original edges. A replacement strap is often less important than a replaced dial, hands, crown or incorrect bracelet. Moisture, rust and battery leakage are warning signs.

Collector interest

Demand depends on maker, model, movement, rarity, provenance and originality. Original box, papers and correct bracelet may increase interest. Natural patina should be distinguished from moisture or corrosion damage.
