Description
Known as “Grande Ellipse” or “Elletrico”, reference 3603 was in production from 1973 until 1982 and is together with references 3587 and 3597 amongst the largest rectangular wristwatches ever made by Patek Philippe. Available in either yellow or white gold with Ateliers Réunis cases, the dials were made by Stern Frères from a massive 18K gold plate and were available in either blue, gilt, browned or silvered finishes.
Reference 3603 houses the Beta 21 movement that was revolutionary at the time. It was used by many other brands to power their quartz watches. This watch was a huge step in a different direction for Patek Philippe and remained the largest watch they made until the 21st century. This is an early example of the reference as the 3603 was produced from 1973 to 1982.
