What's your watch
really worth?
A watch's value lives in its reference, its condition and whether it has its box and papers. Assay blends current dealer asks and auction results into one fair value — so you know the number before you buy, insure or sell.
How to value watches
For watches, the reference number is everything — it pins down the exact model, dial and era. From there, condition (original parts, unpolished case, working complications) and completeness (box, papers, service history) set the premium.
Provenance and rarity then do the rest: a documented owner or a scarce dial variant can multiply value, as Paul Newman's own Daytona showed at $17.8M.
Assay reads reference and condition signals, weighs dealer asks against realised auction results, and returns a fair value with a confidence range — not a single optimistic ask.
Reference & dial
The exact reference, dial variant and production year anchor everything else.
Condition & originality
Unpolished cases, original dials and serviced movements command the premium.
Box & papers
A complete 'full set' can lift value substantially over a bare watch.
Provenance & rarity
Documented ownership and scarce variants turn a good watch into a record.
