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.

THE DESIGN
This particular Ellipse has a wider bezel than the standard and a Space-Age feel, which is consistent with the period. Furthermore, its silver dial adds to this widened design through its monochromatic aesthetic matching its stainless steel surroundings.

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.

THE CONSTRUCTION
Wearing incredibly comfortably on the wrist, the ref. 3580's squared oval 35mm stainless steel case perfectly slots onto the divot behind your hand. Additionally, its crown-less design means it is perfectly symmetrical.
Condition
Watch in overall excellent condition. The case shows light signs of wear with some surface scratches and marks visible on the bezel and case. Silver colored dial in near-mint condition with little to no signs of aging. The watch comes on a worn non-Patek strap with a generic buckle.
Please Note: Due to CITES considerations, if the watch is to be shipped outside of the USA, the exotic skin strap will have to be removed.
Our Perspective
An icon in Patek's historical catalog, the ref. 3580 has become synonymous with Patek's efforts to offer new watches that break from their convention over the years. Made of steel and boasting a rather unusual design, the ref. 3580 has become a collector favourite for all the right reasons.
