Launched in 2000 to commemorate the new millennium, the Patek Philippe ref. 5100 forms part of a four-piece limited run with an 18kt yellow gold variant of 1500 pieces, and three other metals, 18kt rose gold, white gold, and, of course, platinum, totalling another 1500 pieces. 750 of these 1500 pieces are in rose gold, 450 in white gold and 300 in platinum. Powered by an entirely new, at the time, chronometer movement with an impressive 10-day power reserve, the manual-wind cal. 28-20 represented a first in watchmaking as this rectangular movement featured a power reserve indicator and subsidiary seconds dial along with being issued a unique rating certificate issued jointly by the C.O.S.C. and the Geneva Seal Institute. With its elaborately designed 18kt white gold case flaring out at its center and featuring a gentle curve that wraps around the wrist, the ref. 5100G is a splendidly comfortable timepiece, as it wears just as it is styled, with class and elegance. Inspired by the mid-century ref. 2554, the ref. 5100 is a heritage-inspired timepiece with a classic feel and aesthetic. Featuring a gently-textured blue dial with applied Arabic numerals and indices along with its dauphine hands, this timepiece is stunning, rare, and well worth some serious consideration by any seasoned Patek Philippe collector. As a way to ensure that this reference is never produced again, Patek even went as far to destroy the tools used to make the 3000 examples so as to guarantee that even if a later revival of this model was to be made it would still be different.

Boasting everything a collector could look for in a classically-inspired Patek, the ref. 5100G is both spectacularly rare as a commemorative timepiece and a wonderful example of Patek Philippe's craftsmanship with its manual-wind movement, elaborate case, and stunning blue dial.
