Art Deco Jump Hour Wristwatch Case Swiss Chrome Case Unused

Art Deco Jump Hour wristwatch case offered in unused vintage condition.

An attractive Swiss-made Art Deco watch case designed for a jump hour wristwatch movement. The case features the characteristic elongated proportions associated with many jump hour designs of the interwar period and would make an interesting restoration or watchmaking project.

The case appears to have remained unworn throughout its life, although minor storage marks and age-related signs may be present from decades of handling and storage. The interior is marked “Swiss” and “Metal Chrome”.

Jump hour watches became particularly popular during the Art Deco era, offering an innovative alternative to traditional dial layouts. Their distinctive digital-style display remains highly sought after by collectors today.
