Patek Philippe 3848 Ellipse Onyx 1978

Patek Philippe Golden Ellipse 3848 – Mid-Size Perfection with Onyx Stone Dial 1978

Since its debut in 1968, the Patek Philippe Golden Ellipse has stood apart from traditional watch design. Inspired by the mathematical harmony of the golden ratio, the Ellipse perfectly balances round and rectangular forms, creating one of the most elegant silhouettes in horology.

This rare reference 3848/900, known as the desirable mid-size model, captures that philosophy beautifully. Crafted in 18k yellow gold, the watch features a black Onyx stone dial, which contrasts perfectly against the warm gold case.

Inside beats the manually wound Patek Philippe Cal. 215, a movement celebrated for its reliability, elegant construction, and timeless simplicity.

A beautifully preserved Golden Ellipse — combining perfect proportions, Onyx stone dial, and classic Patek Philippe refinement.
