Ulysse Nardin 660-88/212 Sonata Dual Time 18K White Gold Gray Dial

The Ulysse Nardin 660-88/212 Sonata Dual Time stands as a testament to the brand’s innovative spirit and technical prowess. Crafted in solid 18K white gold, this sophisticated model combines bold aesthetics with a remarkable array of complications. At its heart beats an in-house automatic movement, supplying both dual time functionality and the celebrated mechanical alarm with cathedral gong – a rare feature appreciated by advanced collectors. The bold gray dial integrates luminescent markers, a big date, and intuitive settings for the alarm and second time zone, catering to frequent travelers and aficionados of horological engineering. Released in the early 2000s, the Sonata pioneered the seamless integration of a mechanical alarm and a GMT function, both controlled via pushers for ergonomics and ease of use. With its substantial wrist presence at 42mm diameter and a thickness of 13.3mm, the finely finished white gold case houses complex mechanics while maintaining elegant proportions. This model exemplifies Ulysse Nardin’s history of highly technical, marine-inspired watchmaking, and remains a sought-after reference for those who value rare, mechanically innovative luxury watches. Excellent Condition with Ulysse Nardin box and service papers dated 2025.
