You probably don’t know this, but Jaeger-LeCoultre didn’t just produce wristwatches. Not to mention the famous Atmos clocks, the manufacture is at the origin of the famous ADOS table watches.
This ADOS clock is typical of the 1950s, and we know that the prestigious Hermès house distributed some of them, hence affixing its name. The leather, although in good condition, shows some signs of wear.
