A Chrono24 dealer updates his 5711/1A ask every 47 minutes in peak hours. Most flippers refresh their pricing sheet 2x a day.

That is why the spread between Chrono24, WatchBox, and Bobs sits in plain sight — and almost nobody catches it.

Three pricing clocks, one reference

Each marketplace runs on its own refresh cycle:

Chrono24 : global dealer feed, fastest.

WatchBox : curated trade-ins, lags 1-3 days.

Bobs Watches : US retail walk-in, lags 5-7 days.

Same 116500LN, three different price clocks running side by side.

The 60-second method

Pull the lowest unworn-condition listing on each platform. Filter to the same reference and year. Flag any pair where the cross-platform delta is >7% net of fees.

That is your shortlist. Everything else is noise.
