Patek Philippe Ellipse 18K Blue Dial Diamond Set – Ref. 3849

A Rare Factory-Diamond Masterpiece With Heavy Integrated Bracelet

The Patek Philippe Ellipse Ref. 3849 is one of the most elegant and elusive expressions of the Ellipse line, distinguished by its factory diamond-set configuration, blue Sigma dial, and luxurious heavy 18K yellow gold bracelet. Produced in extremely small quantities, the reference was created exclusively for diamond-set examples, making it one of the most collectible and distinctive variations of the Ellipse family.

A Factory Diamond-Set Ellipse – Blue Dial, Sapphire Crown, and Exceptional Finishing

This example features the iconic blue Sigma dial adorned with four factory-set diamonds placed at 12, 3, 6, and 9 o’clock—an elegant layout that maintains the clean geometry of the Ellipse while adding a refined sparkle.

Surrounding the dial is a factory diamond-set bezel comprising 60 natural diamonds, each stone precisely placed to represent a minute on the minute track—a subtle yet extraordinary detail reserved for Patek Philippe’s most artistic jewellery-watch creations.

A blue sapphire Patek Philippe crown further enhances the sophistication of the piece, harmonizing perfectly with the deep blue dial.

Golden hands complete the composition, offering a warm contrast against the dial’s rich hue.

Heavy 18K Yellow Gold Integrated Bracelet – Exceptional Craftsmanship

One of the standout features of this Ref. 3849 is its stunning and substantial Patek Philippe bracelet in solid 18K yellow gold, fully integrated into the case. The bracelet adds both visual presence and tactile luxury, with a length of approximately 17.5 cm, making it ideal for most wrists.

The bracelet ends in a Patek Philippe–signed buckle with a micro-adjust system, ensuring a precise and comfortable fit—an uncommon and highly desirable detail for vintage Patek integrated bracelets.

Both case and bracelet appear unpolished, retaining original edges, geometry, and surface character—an important attribute for collectors who appreciate untouched condition.

Calibre 215 – Manual-Wound Patek Philippe Purity

Inside the reference beats the Patek Philippe Calibre 215, a beautifully finished manual-wound movement celebrated for its reliability, thin profile, and precise timekeeping. This example is reported to keep time very well, a testament to both the movement’s robustness and the careful stewardship of the watch since its original purchase.

The sapphire crystal remains perfect and spotless, allowing unobstructed appreciation of the dial and diamonds.

Originality and Provenance

Offered straight from the first owners, this watch presents an exceptionally rare opportunity to acquire a high-jewellery Ellipse in outstanding, preserved condition.

The reference 3849 is effectively the diamond-set counterpart to the more commonly seen Ref. 3848—but unlike the 3848, the 3849 was exclusively produced in factory diamond-set configurations, making surviving examples exceedingly scarce.

Given its untouched condition, factory diamond setting, and heavy gold integrated bracelet, this piece represents one of the most refined Ellipse executions ever produced.
