A small late 19th-century Swiss cylinder watch in a diamond-encrusted gold open-face case. The keyless gilt bar movement has a going barrel, plain cock with polished steel regulator, and a plain three-arm gilt balance with blued-steel spiral hairspring. The polished steel cylinder and steel escape wheel complete the movement.

The white enamel dial features blue Arabic numerals, gilt minute markers and decoration, and gilt hands. The petite open-face case is entirely set with diamonds, the back pierced to accommodate concentric circles of graduated stones. The plain white-gold cuvette is gilded on the inner face, and the trefoil diamond-set bow completes the design. The watch comes in a fitted gilt-tooled square leather box.
