Introduced in 1968, Patek Philippe's Ellipse owes its design to no accident. It is based on the golden ratio, considered the “divine proportion” found in nature as well as in the greatest works of architecture and art.

The dials, made by specialist Singer for Patek Philippe, offer a simple yet striking contrast between the yellow gold hour-markers and hands and the blue dial with its sunray finish. The dial features a rare “GÜBELIN” signature, a Patek Philippe retailer historically based in Lucerne, Switzerland, and models bearing this retailer's name are particularly sought-after.

Over the course of its production, four different types of dial were used. We have written a full article on this subject, which you can read [here](https://www.41watch.com/fr/blog/revue-historique-de-la-patek-philippe-ellipse-n178). The model we have here features a first-generation dial.

The “Sigma σ” symbol on the dial at 6 o'clock was introduced in the 1970s by the Association pour la Promotion Industrielle de l'Or (APRIOR), and highlights prestigious manufactures that use precious materials for their watches and indicates that the hands and indexes are made of gold, as is the dial for this model.

This version of the Ellipse, whose dimensions are very similar to the original model, is equipped with a hand-wound mechanical movement, caliber 215, which appeared in 1974 and is still in use today. Caliber 215 was the first to be equipped with Gyromax, operating at 28,800 beats per hour. This movement boasts remarkable stability over long periods, making it ideal for everyday use.

The watch comes with an extract from the Patek Philippe archives (on order).
