Reference and dial variant
A discontinued dial variant can add double-digit percentages over the standard reference.
Collectible watch value turns on reference, dial variant, movement, and completeness of box and papers. PROVENANCE tracks live Chrono24 and auction comps against a full-set multiplier, then adjusts for service history and polishing so a refinished case is valued honestly.

Across the watches market four variables decide most of the price: reference and dial variant, box and papers, polish and case condition, service history. PROVENANCE records each of them at the item level so a valuation carries its reasoning with it.
A discontinued dial variant can add double-digit percentages over the standard reference.
A full set typically commands roughly a 25% premium over a head-only example.
Unpolished cases with original grain are worth more than refinished equivalents.
Documented servicing at the manufacturer supports value; undocumented work raises provenance questions.
The watches template asks for 6 specialist fields instead of a generic title-and-value box, so every entry carries the detail an appraiser or a buyer will ask for.
A full set with box and papers adds roughly 1.25×.
These are real entries from the seeded workspace, each carrying a condition factor, cost basis, current value, and unrealized gain. Open any entry to see its valuation history, provenance timeline, and comparable sales.
