Our remarks

Patek Philippe Vintage Jumbo Ellipse Date Automatic – Ref. 3605 – 18k Yellow Gold – Honey Gold Sigma Dial – 18k Milanese Bracelet – Box – 1973 — Total Length 21cm

We are delighted to present this rare and highly desirable Patek Philippe Vintage Jumbo Ellipse, reference 3605, made in 18k yellow gold and originally delivered in 1973.

An outstanding example of Patek Philippe’s refined design philosophy of the 1970s, this Jumbo Ellipse embodies understated elegance, exceptional proportions, and the timeless harmony inspired by the Golden Ratio—hallmarks of the Ellipse collection since its introduction in 1968.

The generously sized “Jumbo” Ellipse case, executed entirely in warm 18k yellow gold, displays beautifully preserved surfaces with elegant curves and a slim, sophisticated profile. Complementing the case is the original and highly sought-after 18k yellow gold Milanese bracelet, which integrates seamlessly and enhances the watch’s luxurious yet fluid presence on the wrist.

The watch features a stunning honey gold-colored Sigma dial, distinguished by its applied gold baton hour markers and discreet sigma symbols flanking “Swiss” at 6 o’clock—confirming the use of solid gold indices, a detail prized by collectors. 

Powering this timepiece is a Patek Philippe automatic movement (legendary, thought JLC based, and same as in the Nautilus), celebrated for its reliability, slim construction, and exceptional finishing, ensuring both mechanical excellence and everyday wearability.

Preserved in excellent condition and accompanied by its original box, this reference 3605 represents a rare opportunity to acquire a true vintage icon from one of the most elegant eras in Patek Philippe’s history.

“Quite rare and beautifully preserved Jumbo Ellipse Date, this reference 3605 in 18k yellow gold with Sigma dial and original Milanese bracelet stands as a quintessential expression of 1970s Patek Philippe design—highly collectible, timeless, and unmistakably sophisticated.”
