1970s Silver Slinky Bangle Blue Dial

A wonderfully unusual 1970s Nivada that feels as much like a piece of modernist jewelry as a watch. The oval .800 silver case frames a deep blue dial with horizontally oriented baton markers and matching baton hands, its simple design allowing the bracelet to take center stage.

The integrated silver bracelet is the real attraction. Formed from a continuous series of elongated loops, it behaves almost like a slinky—compressible and remarkably flexible while still returning to its shape. An adjustable tab engages the repeating loops near the end of the bracelet, allowing the two sides to overlap neatly when sized smaller. Both the case and bracelet are stamped A*D 800, with the bracelet additionally marked Germany; the A*D hallmark is associated with Andreas Daub of Pforzheim.

Powered by a 17-jewel Swiss manual-wind movement, this is an inventive little watch whose appeal lies as much in the cleverness of its construction as in its bold 1970s design.
