This listing offers a single pricing dimension: Product Access (Units). It is free, so you pay nothing to subscribe. The one dimension grants you access to the product, with no tiers, seats, or usage add-ons to choose between. Because there is only one option, pricing does not scale with volume or team size on the Marketplace. You gain access to the underlying luxury watch authenticity index data once your subscription is active.
Top-of-mind questions for buyers
What does the free Product Access (Units) dimension actually grant me on the Marketplace?
It grants access to the Global Tool Watch Authenticity Index data once your subscription activates. The data covers luxury watch auction results and secondary-market pricing. You pay nothing to subscribe, and there are no seats, usage add-ons, or tiers to configure.
Does my cost change as I query more watch records or grow my team?
No. This is a single free dimension with no usage variability, tiers, or per-seat pricing. Your cost stays at zero regardless of how many records you access or how many people use it on the Marketplace.
How current and broad is the watch data I receive access to?
The watch dataset draws on auction and private-sale records refreshed on a daily cadence as sales close. Coverage spans many luxury and vintage watch brands and decades of historical results. Access begins once your subscription is active.
