This is one of two “mystery” watches unveiled by Cartier this week in
Geneva — the Rotonde de Cartier Mysterious Double Tourbillon. As the
name implies, it is a double tourbillon, with two axes of rotation. The
first tourbillon rotates at a rate of one revolution per minute. The
tourbillon carriage (crafted of titanium) has no visible connection to
the rest of the movement – hence “mysterieuse”. As with other watches
of a similar nature, the tourbillon is mounted on a sapphire disc which
itself makes one revolution every five minutes. Thus the the
tourbillon rotates once a minute while simultaneously traveling around
the dial once every five minutes. Impressive. Great High-res pics and
more info, below.
