The Reference 1518 is in production from 1941 to 1954. In the following of some pre-war prototypes, it is the first commercial model to offer altogether these two appealing complications which are the chronograph and the perpetual calendar, in addition to the moon phases.
It is ahead of its time and patrons do not rush. 281 watches are built in this reference which is an average of 20 per year. Most are in yellow gold. 34 of them are in pink gold : one of them previously discussed in this column was sold for $ 795K including premium by Antiquorum on April 10, 2013 ; another one, made in 1948, is for sale in Geneva by Phillips on November 13, lot 196.
The 1518 in stainless steel are extremely rare : only four are known. This is not really surprising : we must indeed recognize some contradiction between the need for a perpetual calendar and the fear of wear.
The first two 1518 in stainless steel were manufactured in 1943 and sold together to a same customer in February of the next year. One of them remaining in an immaculate condition had probably been intended by him as a spare. It is for sale by Phillips in Geneva on November 12, lot 38. The press release of September 22 is announcing an estimate in excess of CHF 3M.
