Distinguishing Features:

1. The Master Tourbillon Heritage: The Calibre 978 is a legendary movement within the Maison, famously winning the International Chronometry Prize in Le Locle. It is celebrated for its stability and precision in a complication that is traditionally delicate.

2. Monochromatic Brilliance: Unlike the warm tones of the pink gold Ref. Q3412410, the Q3413403 utilizes the cool luster of white gold and white mother-of-pearl to maximize the "fire" and brilliance of the diamonds.

3. 360-Degree Setting: The inclusion of diamonds on the case edge and crown ensures the watch sparkles from every angle, not just when viewed top-down.

4. Automatic Convenience: Despite the high-jewelry nature, the automatic winding system (featuring a 22k gold rotor) makes this a practical "daily" grand complication for the serious collector.
