Échappement Opens the Watch Before It Sells It

Field notes

The catalogue groups 110 lots across wristwatches, pocket watches, clocks, and workshop tools, with the sale held in Besançon four times a year. Its inspection framework records the calibre, replaced parts, dial condition, observed 24-hour performance, and service documentation. The site also offers unusually practical seller guidance: a repair costing €400–€1,500 may not return its full cost, while polishing an old case can permanently remove evidence collectors use to judge it.
