On May 10, 2015, Phillips sold for CHF 4.6 million including premium over a lower estimate of CHF 1M a Patek Philippe 130 made of steel in 1927. This model corresponds to the development of the single-button chronograph. This result far beyond the expectations shows a growing interest by connoisseurs for exceptional models in unusual configurations.
On November 7 in Geneva, the same auction house sells a Patek Philippe 1436 made of stainless steel in 1945, lot 169 estimated CHF 1.5M. This split-chronograph model was a significant technological advance. Only one other steel example is surviving.
The watch for sale, still in an as new condition, has probably never been worked on after leaving the factory. Its movement has clearly never been dismantled.
Lovers of exceptional watches must note the information provided in the catalog that there is no known steel watch in the 2499 and world time models.
SOLD for CHF 3.3M including premium
