Zenith Vintage Ultra-Thin Watch in 18K Solid Gold Splendid and elegant vintage Zenith dress watch, dating from the 1970s, characterized by a minimalist style with era-luxury inspiration. The watch has been serviced and is in perfect working order. 1. Codes and Materials (Case Back Analysis) • Entirely Gold Structure: The watch is all gold, made entirely from precious metal in both the case and the integrated bracelet. • 18 Carat Solid Gold: The 18K inscription on the outer case back confirms the manufacturing is solid gold at 750‰, not simply gold-plated. • Total Weight: 68 grams (including case, movement, and bracelet). • Model Reference: The engraved number 30 0730 172 follows Zenith’s classic nomenclature introduced from 1972: • 30: Material code (specifically associated with 18k yellow gold). • 0730: Model and case shape identifying code. • 172: Identifies the internal movement caliber. In that era, this specification referred to ultra-thin hand-wound movements of high precision. 2. Dial and Crown Details • Dial and Measurements: Clean milk-white, measuring 2.5 x 3.5 cm. Features subtle applied geometric indices and black/gold baton hands. At 12 o’clock is embellishing the period’s classic Zenith logo (the square with the inverted four-pointed star). • “Swiss Made” Inscription: Placed at 6 o’clock, stamped with the correct contemporaneous font. • Winding Crown: Original and knurled, with the coordinated Zenith logo raised. 3. Case, Strap, and Dimensions • Case Thickness: 5 mm. An ultra-thin profile of the highest craftsmanship, designed to slide under the shirt cuff with maximum elegance. • Integrated Bracelet: Beautiful gold-link bracelet with squared blocks, integrated directly to the case in line with 1970s design values. There is no visible 18k gold hallmark, but a quality test was performed and certified by the jeweler who serviced the watch. • Overall Length: 18.5 cm. • Clasp: The box-style clasp with adjustable slider clearly shows the stamp with the Zenith logo on the outer track, confirming the piece’s absolute originality. Total serviced May 2025.
