The IWC Da Vinci ref. 3750 is considered an iconic watch since its introduction in 1985. The combination of a perpetual calendar, year display and perpetual moon phase display was unique, especially at a price that wasn’t stratospheric. In the next 20 years, the Da Vinci perpetual family covered a series of variations in case material (steel, gold, platinum), complications including rattrapante and tourbillon and case (39 & 41 mm.)
The brilliance of it’s technique is described thoroughly on the net. Watchmaker Nicholas Hacko mentions his professional respect for the complexity of a 3750 (http://nickhacko.blogspot.nl/2011/07/iwc-da-vinci-ref-3750.html), and http://www.mkmotorsport.com/watches_IWC.html shows detailed specification of the 3750. At Timezone, I found a very readable article by Walt Odets. (http://people.timezone.com/library/horologium/horologium0015)
In 2005, the 3750 and it’s successor, the larger 3758 were replaced by a new generation. In this article, we take a closer look at the availability and market value of the 3750-series.
Ref. 3750- Gold (1985-2005)
The classic 39mm was available in yg and white dial. 17 examples show up at chrono24, ranging in price from $ 10-24,000. Of course, condition and service history are very important for these watches. Very few watchmakers are able to service or repair this watch. The 3750 is mostly seen with champagne dial. The rarer black dial version shows no difference in value. The rare ceramic version is hardly seen on the market.
At auction houses, good deals could be had in 2012. Danish auction house Bruun Ramsussen sold 2 examples in the last two years, at $ 6500 and $ 7700 respectively. Bonhams and Antiquorum sold examples in the $ 8800/10,000 range recently.
Ebay US shows a beautiful example at $13,000, while Ebay Germany starts at 7900 euros for a fair one.
Ref. 3750- Steel (1998-2005)
In 1998, the steel Da Vinci appeared, featured with a black dial. In the current market, these are valued slightly less, starting at $ 7500 at chrono24. Mint and fully serviced ones easily reach values comparable to the gold version. Auction houses show similar prices.
Ref. 3751/3754- Rattrapante (1998-2005)
In 1998, the split-second version was introduced, first in 39mm, and later in bigger 41mm version (3754), both in gold and platinum. The gold ones range from $17-25,000 on the market. The limited edition platinum versions are of higher value.Recently, a platinum one sold at Ebay for slightly under 30,000 euros.
Ref. 3758 (2005-2008?)
The larger-cased non-rattrapantes carry reference number 3758. These versions rarely come to market. Steel ones start at $ 12,000 and gold versions are in the $ 18/24,000 region.
Ref. 3752- Tourbillon (2001-2006?)
The Tourbillon was the pinnacle in mechical timekeeping. A true understatement, as the only sign on the dial was the mention “tourbillon”. Of course, the sapphire glass back shows the masterpiece in all its beauty. With 50 examples produced in platinum and 200 in yellow gold, these items are rarely seen. Chrono24 shows two gold ones in the $40-46,000 area, and one platinum at $ 47,000.
