A fine late-19th-century Swiss enamelled ball watch in the form of an apple, set with diamonds and accompanied by a matching brooch. The watch features an unusual keyless gilt movement, engineered with the train wheels positioned above the going barrel. Its small white enamel dial bears blue Arabic numerals, with the 12 o’clock numeral highlighted in red, gilt minute markers, and blued steel hands.

The case is constructed in three parts: a gold middle band set with a row of diamonds, and two gold hemispheres decorated with applied gold foliate motifs set with diamonds over an engine-turned ground. Between the foliate elements appear panels of shaded translucent red enamel. The watch is wound and set by turning the upper hemisphere of the case relative to the lower.

The ensemble includes a fine matching brooch of gold and enamel, diamond-set and shaped as leaves and a flower. The set is housed in a shaped red morocco presentation case, gilt-decorated and lined with black velvet.
