LONGINES "Ultra Chron" Watch in Yellow gold, Silver, and Leather

Longines Ultra-Chron Automatic (1970s) – 18-carat gold – Recently serviced (12-month Warranty) – Original box. Rare and highly sought-after, this Longines Ultra-Chron embodies the technical excellence of the Longines manufacture in the late 1960s. Equipped with a high-frequency movement (36,000 vibrations per hour), the Ultra-Chron Caliber 431 was among the most accurate watches of its period. This high beat rate enhances running stability and attests to Longines’ watchmaking expertise during the golden age of Swiss mechanical watchmaking. An 18-carat yellow gold cushion-shaped case (33 x 33 mm) with very modern proportions, featuring a superb hue that shifts between yellow gold and a subtle rose gold tint. Remarkable condition: edges still sharp, uniform surfaces, very few marks. Case back and bezel are virtually flawless. The original silver dial is exceptional: the sunburst finish is intact, the applied hour markers are impeccable, and the logo and “Ultra-Chron” inscription are perfectly defined. No visible oxidation. Hands are consistent and well-preserved. Plexiglas crystal. Automatic movement recently serviced by Atelier des Tocantes in Paris with a 12-month Warranty: functioning optimally, ready to wear with no additional costs expected. Fitted with a custom-made ABP Concept Paris lizard-skin bracelet, elegant and perfectly suited to the watch. Comes with its original box and outer box.
