This exquisite Vacheron Constantin complicated watch – the Malte Tourbillon Regulator houses a hand-wound mechanical movement (caliber 1790R) that offers a tourbillon escapement (an escapement that compensates for errors in timekeeping due to the effects of gravity), and the indication of the hours and minutes on a regulator style (off-center) dial.
This is an exquisitely executed work of mechanical prowess, superior watchmaking and beautiful design 
balance. The small seconds’ indicator is on the tourbillon cage. The watch also features a power reserve indicator (approximately 45 hours) and a “Clous de Paris” external dial design. It is crafted in platinum and has a transparent sapphire caseback to view the intricacies of the hand-built movement. It can be yours if you have a simple $205,000 to plunk down – a lifetime of “oohs and ahhs” every time you or someone else looks at it.
