Régulateur - 315605 - 1900-1949

Overview
This is a very large antique mechanical pocket watch with the dial marked Régulateur. The case measures approximately 62.69 mm in diameter, with a watch weight of approximately 142.63 g, giving it a much stronger presence than a standard pocket watch. It features a white enamel-style dial with black Arabic numerals, blue 13–24 hour markings, a subsidiary seconds dial at 6 o’clock, and ornate gold-tone hands. The inner cover is marked 0.800, and the back cover is decorated with a coat-of-arms style engraving. The inner cover also carries technical inscriptions including Spiral Breguet, Ligne Ancre Droite, and 15 Rubis. Its key selling point is the combination of oversized case dimensions, 0.800 silver case, Régulateur dial, and decorative engraved back.
