he Patek Philippe Celestial ref. 6102R-001 was launched back in March at Baselworld 2015. This exceptional reference, was originally launched as reference 5102 in 2002 and discontinued in 2012 when it was replaced by ref. 6102P-001 in platinum with blue dial. One of the main differences between the ref. 6102 and its predecessor ref. 5102 besides the relatively different case construction is the addition of a date function. For those of you in love with gold, we have some great news, the legendary Patek Philippe Celestial ref. 6102 is now also available in 18K rose gold with a stunning black dial. Fitted with robust, yet elegant case measuring 44 mm in diameter and a dial featuring what is called a 'Sky Chart', this reference is one of the most fascinating horological complications ever developed by Patek Philippe. The 'Sky Chart' is composed of three different sapphire crystal disks.
