Preserve the watch as received
Do not polish, replace parts or discard boxes, links, receipts and service papers before identification. Small accessories can answer reference and ownership questions later.
Identify the exact reference safely
Use case, dial, bracelet and partially covered serial-area evidence. Avoid posting a full serial publicly and do not open the watch without a qualified reason.
Separate three kinds of value
A market estimate, direct purchase offer and formal appraisal serve different purposes. Estate, insurance and tax questions may require qualified professional advice outside a seller calculator.
Confirm authority to sell
Make sure the estate, executor or beneficiaries have authorized the transaction and keep the supporting ownership record private and organized.
Choose the route after the evidence
Compare direct sale, consignment, auction and private sale only after condition, completeness, service risk and likely buyer depth are understood.
