Up for sale is a Patek Philippe 3545 Ellipse 18K White Gold 1970s. Patek Philippe introduced the Ellipse reference 3545 in 1969 and it remained in production for approximately 10 years. This watch was offered in many variations and this particular example is cased in 18K white gold with a beautiful blue linen dial. Powered by the ultra-thin, hand-wound Caliber 23-300, this Ellipse represents Patek Philippe’s commitment to pure mechanical beauty beneath an artful exterior. As the name implies, Cal. 23-300 is 23 mm (10 ligne) in diameter and 3 mm tall. Cal. 23-300 is classic in layout, with a barrel bridge covering the ratchet and crown wheel, a curved center wheel bridge, and separate cocks for the fourth and escape wheel. It was derived from the preceding Cal. 10-200 but with many modifications. It is notable in that it is equipped with both an overcoil hairspring and a free-spring Gyromax balance, a combination not found in any other 10 ligne Patek Philippe movement. This movement is greatly respected today, with many saying it is one of the best hand-wound movements ever produced by Patek Philippe. Carlos Perez said it “represents both the technical and artistic peak of Patek's 10 ligne handwinds, as the 27-AM 400 was the peak of their 12 lignes.”   MANUFACTURED: Around 1972 MOVEMENT NO: 1'217'798 CASE NO: 2'726'725 CASE MATERIAL: 18k white gold CASE DIAMETER: 32 x 27 mm.
