Accompanied by Patek Philippe Extract from the Archives confirming production of the movement of the present watch in 1927 and its subsequent sale with stainless steel case and silvered dial featuring black enamelled hour markers and pulsation scale on 24 March 1937.
The single button chronograph mechanism is considered to be amongst the most complex and sophisticated marvels of time measurement. Whereas the more commonly found operates the chronograph functions (start - stop - reset) through two buttons in the band, the single button chronograph controls all of these functions through the crown. The ébauches for these chronographs were commissioned by Patek Philippe and made by Victorin Piguet of Le Sentier. It is assumed that Patek Philippe produced single button chronograph wristwatches only between the mid 1920s and the late 1930s.
All known single button chronograph wristwatches were cased in yellow gold, either in early forms such as cushion, tonneau or Officier-style cases, later in the classic reference 130 design.
Research has resulted in the identification of only two stainless steel single button chronograph wristwatches by Patek Philippe. The present watch, case number 504'146, and an identical twin with the case number 504'147.
It is interesting to note that the two watches are exactly made with the same distinctive specifications, which are the large stainless steel case with a diameter of 35.2 mm., the vertically placed subsidiary dials and the silvered sector dial with pulsation scale. Most interestingly, both watches were sold on the same date, 24 March 1937, presumably to Walser, Wald & Cia, Mar del Plata, Buenos Aires in Argentina. The second watch is now property of the renowned Patek Philippe Museum in Geneva, where it is listed as inventory number P-1227 (see www.patekmuseum.com, The Collection - Patek Philippe Collection - Complex Wristwatches (1925-1989) - The Doctor's Watch).
The present watch is an outstanding example within the family of single button chronograph wristwatches by Patek Philippe, for its spectacular combination of several important features:
- The oversized reference 130 case in stainless steel: whereas the regular steel reference 130 has a diameter of 33 mm., the present watch is unusually large with a diameter of an impressive 35.2 mm.
- The highly sophisticated dial, uniting itself another three rarities, the vertically positioned subsidiary dials, the sector or so-called aviator display and the pulsometer scale.
- The incredibly well preserved, original and unspoilt condition and its impeccable provenance and freshness to the market, as in the same private collection for over a decade.
