Da Vinci Tourbillon Rétrograde Chronograph

IWC 2017

ref. IW393101
Men's

Da Vinci Tourbillon Rétrograde Chronographe square

 

 

This original combination of functions assembles a

flyback Chronograph with hour and minute totaliser in a subdial at 12 o'Clock,

a hacking tourbillon to set the time with to-the-second precision, and a

retrograde date, all in a harmonious layout. The pallet and the escape wheel

are in diamond-coated silicon, an extremely hard surface that reduces friction,

thus compensating for the increased energy used by the tourbillon to maintain

the 68-hour power reserve. As for wearer comfort, the moving lugs on this 44-mm

diameter watch ensure the Santoni leather strap adjusts perfectly to the wrist.
