Zenith - 3021956 / 620 - 1900-1949

Overview

This is a substantial Zenith large-format mechanical pocket watch, measuring approximately 54.39 mm in diameter and weighing approximately 101.99 g. It displays the strong character of an early 20th-century Swiss pocket watch. The white enamel dial features elegant black Arabic numerals, a subsidiary seconds dial at 6 o’clock and finely shaped gold-tone openworked hands, creating a particularly balanced and traditional appearance.

The 0.800 silver case is decorated with fine engine turning on the back and a central ornamental monogram cartouche. One of the most interesting aspects of the watch is the inner dust cover, which carries inscriptions including GRAND PRIX PARIS 1900, ANCRE, 15 RUBIS, BALANCIER COMPENSÉ and SPIRAL BREGUET, adding considerable historical and technical character to the piece.
