Chronomètre de Poche
A pocket watch built to observatory tolerances, in a hinged silver hunter case.
Ø 50.0 × 13.0 mm
Before wristwatches, Sainte-Croix made pocket movements for the world. The OV-4 is our return to that scale: a large, slow-beating balance you can watch through the hinged caseback.
It is adjusted to chronometer tolerances and comes with its own rating certificate, signed at the atelier.
Three pieces, each with a hand-engraved silver case.
