Kessler Uhren GmbH
Specialist pre-owned watch dealer receiving catalogued collections from deceased collectors' families
CHF 1M additional value realised
Premium from structured provenance chains across 30–40 collections per year
The Problem#
- When a watch collector dies, the family often has no idea what the collection is worth — or even what it contains
- Watches may be stored in safes, bank deposit boxes, or scattered across properties in Switzerland and Germany
- Kessler’s specialists currently catalogue, authenticate, and value each piece manually, producing a PDF valuation report
- The solicitor re-keys the values from the PDF, and cannot easily share the catalogue with other potential buyers for competitive bids
- The entire supply chain from “collector dies” to “watches reach the right buyer” is opaque and inefficient
How They’d Use INHERIT#
- Each watch is an
asset.jsonentry withcategory: "collectibles"andsubcategory: "watches", with photographs, condition grades, and authentication certificates attached viacommon/media.json - The collection as a whole is an
asset-collection.jsonwithdisposalStrategy—"sell_as_collection","sell_individually", or"dealer_bids"for competitive offers - Valuations use
valuation.jsonwithproviderType: "dealer",method: "comparable_sales"or"expert_opinion", andvaluationPurpose: "date_of_death"for probate - Kessler’s interest in purchasing specific pieces is recorded in
dealer-interest.json, withofferStatusprogressing from"standing_interest"through"written_offer"to"accepted"or"declined" - The
switzerlandextension handles Swiss-specific succession rules — forced heirship for spouse and children under the Swiss Civil Code - The
catalogue.jsonschema links assets to published sale catalogues, creating a complete provenance trail
The Integration#
- Bidirectional: Kessler imports INHERIT documents from solicitors (receiving the collection inventory), adds valuations and dealer interest records, and returns the enriched document
- The structured format allows the family’s solicitor to share the catalogue with multiple dealers for competitive bidding — impossible with PDF reports
- Other dealers can express interest via
dealer-interest.json, creating a transparent market
The Business Case#
- Structured catalogues with provenance data command a 10–15% premium at resale compared to paper-only documentation
- Across 30–40 collections per year averaging CHF 250,000 per collection, this represents approximately CHF 1 million in additional value realised for estates
- Kessler’s competitive advantage is the structured catalogue — families increasingly choose dealers who can provide machine-readable valuations to their solicitor
- The transparent bidding process benefits families and builds trust in the dealer relationship
Before / After#
Without INHERIT:
- Collector dies — family finds watches in a safe but doesn’t know their value
- Family contacts Kessler, who sends specialists to catalogue and value each piece in person
- Kessler produces a PDF valuation report and sends it to the solicitor
- Solicitor re-keys every value; cannot easily share the catalogue with other dealers for competitive bids
- Family accepts Kessler’s offer without knowing whether it’s the best available price
With INHERIT:
- Collector dies — family contacts Kessler for cataloguing and valuation
- Kessler creates structured
asset.jsonentries with valuations, provenance, anddealer-interest.jsonrecords - Solicitor receives the INHERIT document and shares it with multiple dealers for competitive bids
- Each dealer’s interest and offers are recorded transparently in the same document
- Family gets the best price; the complete provenance chain adds a 10–15% premium
“A watch with a paper certificate is worth one price. A watch with a structured provenance chain — every owner, every service, every valuation — is worth 10–15% more. The market rewards data.”Lukas Kessler, Managing Director, Kessler Uhren GmbH
