IWC - Da Vinci Tourbillon Rétrograde Chronograph

| 1 Comment
Introduced at the Salon International de la Haute Horlogerie held in Geneva last January, the new Da Vinci collection is hitting the IWC Boutiques this week.

Following our articles of the Perpetual Calendar Chronograph, the Chronograph Laureus Edition and the Automatic 40 mm, it is a good time to write about the most exclusive model of the collection, the Da Vinci Tourbillon Rétrograde Chronograph Reference IW393101.


As its name suggests, the model combines a tourbillon with a retrograde date and a sporty chronograph on a single dial. The result is a technically sophisticated and optically balanced complication with a clear and distinctive design.

The eyes are immediately caught by the flying tourbillon at 6 o’clock. Its cage is bearing-mounted only at one end, on the underside, and is not connected to an upper bridge.


The tourbillon also features a technically complex hacking function that guarantees down-to-the-second accuracy when setting the watch. When the crown is pulled out, two levers grip the balance rim like a clamp and block the mechanism. consisting of the balance, wheel train and hands.

New geometry in the pallet and escape wheel combined with diamond shell technology ensures that the watch’s 68-hour power reserve when fully wound is maintained despite the additional complications.

Furthermore, the pallet and escape wheel are made of diamond-coated silicon, an extremely hard surface with good sliding properties that reduces friction and thus resistance, which in turn benefits the power reserve.


Visually balancing the tourbillon, the flyback chronograph subdial at 12 o’clock measures intervals of up to 11 hours and 59 minutes showing them by an analogue display with two hands which can be read off as easily as the time of day. The central seconds hand measures stopped times to an accuracy of one-quarter of a second.

The third complication, besides the chronograph and the tourbillon, is the retrograde date display, located on the left-hand side of the dial. The hand shows the date from the 1st to the 31st of the month as it moves across an arc and then, at the end of the scale, instantaneously reverts to its starting point.



In months with fewer than 31 days or when the watch has not been used for a while, the date display can be advanced rapidly and conveniently using the crown.

Water-resistant to 3 bar, the 44 mm x 17 mm red gold case houses the new IWC-manufactured 89900 calibre which is visible through the transparent sapphire-glass back. Beating at 28,800 vibrations per hour, it offers 68 hours of power reserve.


The imposing case has movable horns ensuring that the dark brown alligator leather strap by Santoni fits comfortably around the wrist. The strap is secured by the 18-carat red gold folding clasp.


The IWC Da Vinci Tourbillon Rétrograde Chronograph (Ref. IW393101) has a suggested retail price of around Euro 110,000 / US$ 103,000. iwc.com
