Jaeger-lecoultre, High jewelry watch series, model: Q1652490 Tourbillon men's watch, 18K rose gold, 41.5mm in diameter, limited to 100 pieces worldwide. The bezel is originally set with brilliant-cut diamonds, which refract a brilliant luster under the light. The dial is based on blue mother-of-pearl, presenting a warm rainbow that changes with the light. Paired with rose gold bar hour markers and hands, it reads the time clearly and exudes a sense of luxury. The circular scale around the dial is a pointer calendar. At 12 o 'clock, there is a GMT second time zone sub-dial, and at 6 o 'clock, there is the iconic tourbillon mechanism. It combines practicality and mechanical aesthetics. The transparent case back automatic winding tourbillon movement (CAL.978 series), with an 18K rose gold folding clasp that echoes the case. A complete set of blank cards.
