    Dimensions summary

    This listing offers a single pricing dimension: Product Access (Units), which grants subscribers access to the product at no cost. Because the product is free, there are no tiers, usage add-ons, or scaling charges to compare. You get access to auction and secondary-market pricing data across luxury watch brands through this one dimension. The unit simply enables entry to the dataset for subscribers without any billing beyond the free access.

    Top-of-mind questions for buyers

    It grants entry to a luxury watch pricing dataset. The data covers auction results and secondary-market prices across many watch brands. Records are cleared prices — what watches actually sold for — converted to USD at the transaction date. Access is granted to subscribers at no cost.
    The dataset updates daily. New results flow in as sales close at auction houses worldwide. The date range runs from 2000 to today, with daily latency and daily update frequency. Because access is free, there is no billing tied to how often you query or refresh.
    They are realized results. Each figure is the hammer price plus buyer's premium, converted to USD at the transaction date. No estimates or list prices are included. This helps you value watches using real sold comparables rather than seller expectations.
