Object description

Design and Case Construction

The Corum Bubble Joker desk clock translates the aesthetic profile of the manufacturer's Bubble wristwatch line into a larger desktop format. The casing is constructed from a solid block of stainless steel, characterized by a rounded, heavy geometry. The piece is surmounted by a bulbous sapphire crystal, a design element intended to evoke the proportions of the original wrist-worn models.

The assembly rests on a PVD-coated black base which functions as a stand. Measuring 80 mm in diameter, the object features a prominent crown-like protrusion on its side, maintaining the visual language of the wristwatch series while serving as a stationary desk accessory.

The surface of the black stand is marked with the Corum name and key symbol.
