A vintage masterpiece of Swiss engineering, this Hebdomas pocket watch features the legendary 8-day power reserve movement. The dial is a beautiful white enamel decorated with silver floral motifs and a unique "open-heart" window at the 6 o'clock position, revealing the oscillating balance wheel. The back of the movement is ornately engraved with exhibition medals (Milan, Brussels, Paris), signifying the brand's historical prestige. Housed in a 0.800 silver case with a hunter-style hinged cover, this timepiece is a quintessential collector's item for those who appreciate early 20th-century mechanical innovation.
