Introduction
An incredibly unusual variant of the Patek Philippe Ellipse, the ref. 3580 is a 35mm oval-shaped stainless steel timepiece with brushed finishing throughout its construction, allowing for an impressive wrist presence thanks to its visual consistency. Fitted with a gorgeous understated silver dial, the ref. 3580 harkens back to Patek's desire to refrain from distracting the wearer from the incredible craftsmanship within their timepiece. Powered by the automatic cal. 350 movement, the ref. 3580 is indeed a Back-Wind watch, whereby its crown has been removed from the case's side and placed on the caseback. This move was inspired by the technology in battery-operated watches, as they never needed their crown for resetting since their batteries wouldn't run out – much like an automatic timepiece if it is continuously worn. A symbol of modernity, progress, and technical innovation, the ref. 3580 is a wonderful testament to Patek and their willingness to step out of their comfort zone and seek inspiration in some of the most unusual places – even if that place is battery-powered watches.

TIMING MACHINE READOUT
This reading was taken (crown down) with a ONEOF Accuracy Boutique Edition timing machine at time of cataloging. It is provided as a courtesy only, and shall not be construed as a warranty or guarantee of any kind. Please refer to our terms and conditions of sale for more information.
Condition
The overall condition of the watch is in very good to excellent condition. Dial is untouched with no indication of any impairment. Although the case has surface abrasions throughout, it still maintains the beveling at the edge. Leather strap and buckle are not original to the watch.
Please Note: Due to CITES considerations, if the watch is to be shipped outside of the USA, an alternative leather strap to the existing exotic skin version, shall be provided.
Our Perspective
This example is from the first year of production of the model. It is accompanied by its authentic Certificate of Origin, as well as its Japanese Guarantee Card and Japanese Patek Philippe literature. One cannot imagine a Patek Philippe collection without an Ellipse-this is a unique chance to own a superlative and complete example.
