Previously owned Ulysse Nardin Freak I gent's watch, Model # 010-88. 18kt white gold 45.5mm case. Sapphire crystal glass. Blue dial with Arabic numeral hour markers. Crocodile leather strap with 18k white gold deploy buckle. Hours. minutes and open tourbillon display. 18k white gold bezel. Manual wind movement. The Tourbillon compensates for differences in rate caused by a watch adopting different positions. The principle is to mount the balance and escapement in a rotating cage. The balance & escapement rotate around their common axis going through all positions to average out the errors, Tourbillon cages or platforms usually rotate once per minute but 4 minute and six minute tourbillons are also found. The Tourbillon complication is an extremely difficult accomplishment to achieve and generally demands a high premium. 100% original and in great condition.
