Jaeger-LeCoultre Master Grande Tradition Tourbillon Cylindrique à Quantième Perpétuel Detail

The Master Grande Tradition Tourbillon Cylindrique à Quantième Perpétuel is a mouthful of a name; suffice it to say that watch has a flying tourbillon and a perpetual calendar, set in a 42mm pink gold case and a beautiful silver-toned grained dial finish.    The perpetual calendar provides a crystal- clear display of the day, date, month and year, alongside with the moon phases; while the small seconds are set above the flying tourbillon.

The automatic winding mechanical movement, Jaeger-LeCoultre Calibre 985 — equipped with tourbillon and a cylindrical balance- spring — is quite a sight to behold.    The 22-carat gold oscillating weight bears a reproduction of the gold medal that Jaeger-LeCoultre won at the 1889 Paris Universal Exposition in recognition of its horological expertise and its spirit of invention.
