Dimensions summary
This listing has one pricing dimension: Product Access (Units), offered at no cost. It grants subscribers access to the Grand Complication Watch Appreciation Index data.

The unit measures product access granted to each subscriber.
Top-of-mind questions for buyers
One unit grants a subscriber access to the Grand Complication Watch Appreciation Index (GCAI) data. It represents access at the account level rather than a physical server or resource. The listing meters access itself, not data volume, so a single unit covers your subscription to this dataset.
No. This dimension is offered at no cost, so your bill does not change with query volume or the number of people using it. There are no included-amount cutoffs, overage points, or tier boundaries under this single access dimension to trigger a cost change.
Access covers watch appreciation index data grounded in auction and private-sale records across major watch houses and the wider secondary market. The underlying data is currency-normalized and refreshed continuously as new results come in. It tracks realized results rather than asking prices or estimates.
