Born from Ulysse Nardin’s spirit of mechanical innovation, the El Toro stands as a bold expression of high complication watchmaking. Showcasing a commanding white gold case framing a dial alive with calendar and dual-time displays, it signals technical mastery designed for collectors who value ingenuity over convention.

Presents itself in mint condition with little to no signs of wear. Showcasing a matte black dial with oversized date display, perpetual calendar windows, and a retrograde date track, this reference delivers bold depth and technical presence. Featuring broad luminous hands and crisp markers against a 24-hour GMT bezel, the layout remains highly legible. Completing the composition, it comes with a UN black alligator strap and UN white gold deploy buckle, as well as a new UN rubber strap and UN black ceramic deploy clasp, offering both elevated elegance and everyday versatility.

Functions include hours, minutes, seconds, and a full perpetual calendar that automatically adjusts for months of varying lengths and leap years. The screw-down crown on the right side of the case winds the movement and sets the time and calendar when pulled to the first position. The top pusher advances the GMT hour forward, while the lower pusher moves it backward. Super-LumiNova applied to the hands and select indices ensures legibility in low-light conditions.

Comes as a full set, double-boxed with a watch pillow, user manual, warranty card, document holder, and UN booklet.

Purposeful, technically daring, and undeniably rare, this reference embodies mechanical ingenuity at its highest expression. For collectors who value true innovation over convention, it stands as a singular achievement with enduring horological significance.
