1930s Jump Hour Anonymous - Bright Blue Lacquer Inlay | Large 25.5mm x 34mm | For 21mm Straps

Jump hour watches from the 1930s sit at the intersection of Art Deco design and mechanical experimentation. At a time when modernity meant reimagining even the simplest things, these watches traded the traditional sweep of hands for a digital-style display, the hour revealed through a jumping disc, clicking satisfyingly into place with each passing sixty minutes. It was playful, futuristic, and perfectly in tune with the optimism of the era.

Nearly a century later, these pieces remain as fascinating as ever, rare artifacts of a period when watchmaking dared to be different. Few have survived in such remarkable condition, and this particular example is a standout. The deep blue lacquered inlay dial glows with an almost electric intensity, a finish seldom seen and even rarer to find preserved so beautifully.

Unusually large for a rectangular case, its proportions, just over 25mm by 34mm, with 21mm lugs, give it an unexpected presence on the wrist. It manages that delicate balance between elegance and assertiveness, the kind of design confidence that defined the best of 1930s watchmaking.
