Vacheron Constantin 4178 chronograph, `40s18k gold round case, n.271258, rectangular pushers, teardrop lugs. Two-tone champagne and orange dial, applied indexes and arabic numerals. Hand-winding movement, cal. 434, n.431331. 14k gold unbranded bracelet. Size: 36 mm. Notes: Reference 4178 was in production from 1940 until the mid `60s, and is one of the most famous and sought-after vintage chronograph made by Vacheron Constantin. It is a very diverse model, iconic thanks to its oversized 36mm case, an unconventional characteristic for its era, which wears the wrist even larger with its distinctive teardrop lugs, a well-known Vacheron Constantin design code. The watch in this catalogue features a one-of-a-kind patina, with the original champagne dial turned to a head-turning two-tone nuance of champagne and orange.
