Antique Gruen pendant pocket watch crafted in 14 karat yellow gold, featuring a finely executed guilloché enamel case and an elegant detachable lapel pin fitting. The reverse displays a radiating engine-turned enamel design centered with an ornate gold crown motif set with small seed pearls, a charming decorative detail characteristic of refined Edwardian jewelry watches.

The white enamel dial displays black Arabic numerals with red outer minute markers and includes a subsidiary small seconds dial at 6 o’clock. The watch is powered by a Gruen Watch Co. Swiss movement with fifteen jewels and adjustment, signed Gruen Watch Co., Cincinnati, and marked Swiss.

The watch measures 30.65 mm in diameter and has a total weight of 26.38 grams. The enamel decoration remains well preserved and the detachable pin allows the piece to be worn as a lapel or jacket accessory.

The watch winds and briefly runs but stops, indicating that service is required, and it is offered accordingly.

Antique Gruen enamel pocket watches with pearl decoration and detachable lapel fittings are increasingly sought after by collectors of Edwardian jewelry watches and early Swiss pocket watches.
