For watch aficionados that desire models big on technical functions and details, this illustrious piece is a must have.

Interesting Facts
The Master Grande Tradition Tourbillon à Quantième perpetual is widely admired and discussed for its two-level construction and dual complication. The timepiece is enlivened by the pace of the two opposing rhythms; the slow rotation of the perpetual calendar and the balance beating at eight vibrations per second. Some of the wheels borne by the perpetual calendar will take almost a 100 years to complete one revolution. Also noteworthy is the Silicon escapement, performance and reliability that this watch offers. The complex parts have been crafted using silicon by a special manufacturing technique due to its light weight and sturdy nature. The new ‘Chronometer 1000 Hours’ test has been performed on the finished models as a measure of chronometric reliability.
