Please Note: The present lot was originally a 3970E but was converted into a 3990E in 2003 at the Patek Philippe workshop. The work is confirmed on the Patek Philippe extract accompanied with this timepiece.

Patek Philippe's reference 3990 was produced from 1995 until the launch of the 5971P in 2007. The Ref. 3990 was the first jewelry complicated wristwatch produced by Patek Philippe in series and was made in yellow gold, white gold, and platinum. It is believed that only 5 pieces were made in platinum. The watches were delivered with an additional caseback, expect in platinum wherein the additional caseback was optional.

The present watch has been consigned by the family of the original owner who received the second white diamond-set dial as a special request.

To the best of our knowledge, this lot has never been offered at auction and is fresh to the market
