What to document first

Open the rear cover only if it can be done safely. Photograph the complete movement, serial number, grade markings, jewel count, adjustment markings, regulator, dial, case interior and exterior. Record the diameter excluding the crown.

Key inspection points

• A dial name may be a retailer rather than the manufacturer.
• Hallmarks and case marks can be especially important.
• Unsigned movements require construction-based identification and caution.

How to compare value

Compare watches by exact movement grade, size, jewel count, condition, case material, originality and service status. A common movement in a gold-filled case is not directly comparable with a scarce railroad grade or solid-gold example.
