Possibly unique 40s holy grail watch for the committed chronograph or Piaget collectors. Scroll down to read more about this incredible watch.



Featured is a stunning Piaget chronograph in 38mm stainless steel stepped bezel waterproof hermetic screw down case with exceptional radium dial housing an early Valjoux 22. This watch was issued by Leonidas as a special order for Piaget.

The overal condition of the watch is extraordinary.
Creme colored dial showing lumed Arabic hour indications matching the color of the patinated ‘pencil’ hands.
The dial shows a subtle and even patina across (see pictures).

The condition of the case indicates this watch has not been worn much. The razor sharp lugs and stepped bezel both in pristine condition.
Steel brushed sides showing no scratches or dents whatsoever.
The two-bodied case has a ‘hermetic’ type of screw down case back with the screw thread on the inside edge of the case back which is rarely seen.These uncommon type of ‘hermetic’ screw down cases provided even more security protecting the movement from dirt and water.

The eight half circled notches in the case back prove to be another aspect which is rarely seen in the vintage watch world.

The superb Leonidas signed early Valjoux 22 movement is as clean as it gets and is running with great accuracy.
