IWC Creates Sophisticated Da Vinci Perpetual Calendar Digital Date-Month Watch

Jan 26, 2009
The Da Vinci watch collection from IWC Schaffhausen is highly appreciated among real watch connoisseurs as it comprises technically and aesthetically sophisticated mechanical timepieces. The timepiece has been unveiled at SIHH 2009.

This year, the prominent IWC watch collection is joined by another timekeeping wonder - a complex wristwatch with a flyback chronograph and a unique perpetual calendar, with date, month, and leap year displayed in digital format.

The timepiece has been inspired by an important stage in the IWC history, when, 125 years ago, the prominent watchmaking house received the rights for a jumping hour mechanism invented by Josef Pallweber, a gifted 19th century watchmaker and inventor.

The IWC Da Vinci Perpetual Calendar Digital Date-Month watch features a tonneau-shaped case, 44mm x 52.8mm, crafted in platinum or 18K rose gold. The case has inherited the intricate finishing details from the IWC Da Vinci Chronograph watch. The case construction incorporates sapphire crystals on both sides.

The elegant silvered dial of the IWC watch reveals a vertical tapestry pattern. It is completed with rhodium-plated or gold-plated hands and indices. The dial demonstrates a remarkable range of complicated features.

At 12 o'clock, you will notice a sub-dial for elapsed chronograph hours and minutes together. Representing an original mechanical solution, the single-dial chronograph is able to keep time the same way as a common watch. The chronograph display may also be used for tracking time in a second time zone.

The digital date and month are also featured in the upper part of the dial, presented via bar-separated twin windows.

The sub-dial for the subsidiary seconds is positioned at 6 o'clock. It has a small cutout showing the leap year cycle.

The IWC Da Vinci Perpetual Calendar Digital Date-Month watch accommodates a prestigious self-winding movement - the manufacture 89800 caliber. The mechanism comprises 474 individual parts.

The unique nature of the Caliber 89800 is revealed through a range of details:

  • a column-wheel control for the chronograph;

  • a double-pawl automatic winding system to guarantee the most effective automatic winding;

  • a remarkable perpetual calendar mechanism that may be adjusted by the wearer with help of the winding crown (the first adjustment by the wearer will be required only in 2100);

  • the integral shock absorber of the spring-mounted rotor;

  • the balance frequency is 28,800 alternations per hour;

  • the spring barrel provides a 68-hour power reserve.


The IWC Da Vinci Perpetual Calendar Digital Date-Month watch is secured to the wrist on a broad alligator leather strap fitted with a folding clasp crafted in rose gold or platinum. The platinum variation of the IWC watch will be available in a limited edition of 500 pieces.
