Zenith - A 510787 - 1900-1949

Overview
This is a classic Zenith Swiss mechanical pocket watch, displaying the elegant character associated with early 20th-century Swiss watchmaking. The white dial features decorative black Arabic numerals, a subsidiary seconds dial at 6 o’clock and attractive gilt openwork hands, creating a clean and refined appearance.
The real highlight, however, is found beneath the back cover. The watch is fitted with a Zenith-signed 17-jewel gilt movement, featuring large gold-tone bridges, visible ruby jewels and contrasting silver-tone winding wheels. The movement has particularly strong visual appeal and is an important part of the collectible character of this watch.
The most notable feature of this pocket watch is its beautifully presented Zenith-signed 17-jewel gilt movement.
