Introduced to the market in 1932, the Patek Philippe ref. 96 was the first serially produced, referenced timepiece by the firm. Considered as the very first Calatrava model, the reference features a three-piece 30.5mm diameter round-shaped case made by Geneva-based master casemaker Antoine Gerlach (identifiable via key no. 4) for yellow gold examples. With a production spanning over 40 years, a total of four series of the reference were produced. Examples of the reference 96 featured small seconds, with more desirable examples featuring center seconds, known as the reference 96 SC – of which the present lot is a superb example.

The present reference 96 SC (“secondes centre”) is part of the first of the four series of the reference 96 SC, bearing the caliber 12’’. It was famed Brazilian retailer Gondolo & Labouriau which requested these movements in 1910, intending them to feature a cam wheel regulator, allowing for precise and practical adjustments to the watch, a moustache-shaped lever, wolf's tooth winding gears, and gold wheels for the wheel train. Based on a LeCoultre ébauche, the indirect seconds mechanism is cleverly hidden under the dial.

Not just rarity within, but rarity without. The combination of long signature and an incredibly attractive, champlevé enamel sector dial preserved in stunning condition, renders the present watch as one of the rarest in existence. Fresh-to-the-market, with a charming monogram on the caseback and elegant proportions, it is a wonderful example of the earliest iteration Calatrava.
