Vintage LeCoultre Art Deco Rectangular Tank, Swiss Dress Watch, 10K Gold-Filled Case, Calibre 413 from 1940's

This vintage LeCoultre rectangular dress watch presents all the charm and quiet presence that defined mid-century American-market Jaeger-LeCoultre timepieces. The 24 × 36 mm gold-filled case has a clean, architectural silhouette with crisp bevels and straight, elongated lugs that give the watch a refined profile on the wrist. The proportions offer a balanced mix of elegance and subtle formality, characteristic of the 1940s–1950s design language.

The dial shows honest aging: a warm, creamy tone with speckled patina that enhances the vintage personality of the watch. Applied gold Arabic numerals are evenly spaced and display a soft, period-correct style. The small-seconds register at 6 o’clock is neatly framed, with slender markers and a small gold hand that ties the composition together. The gold leaf-style hour and minute hands complement the numerals, creating a cohesive aesthetic that feels both understated and distinctly vintage.

This model is powered by the Jaeger-LeCoultre Calibre 413, a well-regarded manual-wind movement used in the brand’s rectangular and tank-style watches of the mid-century era. The movement’s compact form allowed LeCoultre to produce slim, elegant cases without sacrificing mechanical quality.

A key historical note: the “LeCoultre” signature on the dial indicates that this piece was produced for the U.S. market. During this period, the company used different branding depending on region—

• “LeCoultre” for the United States,

• “Jaeger” in France,

• “Jaeger-LeCoultre” in Europe and international markets.
  This variation makes American-market LeCoultre watches uniquely interesting for collectors who appreciate the brand’s transatlantic history.
