The collapse in cryptocurrencies is easing supply of the most sought after watches on the second-hand market, depressing prices for hard-to get-Patek Philippe and Rolex models.

Surging valuations for crypto currencies had minted a new class of luxury buyers, leading to an unprecedented price increase for models particularly from brands like Rolex, Audemars Piguet and Patek. Now that many digital tokens have been hammered, these consumers are going into reverse.

Stracke said trading volumes on the platform, which links dealers or private sellers with buyers, have jumped more than 50% in the first half of the year.

The price of a Patek Philippe Nautilus 5711A, which sells for about $35,000 at retail, surged to $240,000 in the first quarter, according to Chrono24. Now the blue-dialed steel sports watch is fetching about $190,000.
