Thierry Stern, president of Patek Philippe, presents two technically impeccable new watches designed to be particularly fresh and young, but also practical. Reference 5990/1 is a Nautilus with chronograph and second time zone. Thanks to two pushers on the left side of the case, the owner can easily move the second time zone hand forward or backward. Reference 5960/1 is an annual calendar in stainless steel with a more aggressive design and particularly legible indications. Stay tuned as Patek Philippe celebrates its 175th anniversary this year, with more stunning timepieces are to be presented in October.
