Lot essay

Reference 25860 is the first Royal Oak chronograph wristwatch produced since 1997 on the basis of the self-winding caliber 2385, which had just been developed by the brand in collaboration with movement-blank producer Frédéric Piguet as a personalized version of its legendary caliber 1185. The Royal Oak Chronograph Ref. 25860 was available in different variations and was mostly produced in stainless steel, as the present example, and predominantly fitted with a dark blue or a matt silvered ‘tapisserie’ dial, featuring an original small or, later, enlarged ‘tapisserie’ pattern.

The dial design of the present example is characterized by such features as an enlarged ‘tapisserie’ pattern with 4 rows of squares between chronograph counters, round applied luminous markers at 3, 6, and 9 o’clock, “05” on the peripheral minutes/seconds scale, and the digit “2” featuring a rounded top scroll in the “20” and “25” of the peripheral minutes/seconds scale (which is typical for reference 25860). The dial marking of the present example is of Type 1, which may be defined by the distinctive serif “7” digit marker on the chronograph hours counter, while the Type 2 marking has a sans-serif “7”. As usual in the Royal Oak Chronograph of that period with dark dials, the hands are painted white.

An extremely rare so-called tropical patina with the hour and minute hands having a light-cream tone. This rare colour change gives the watch an imposing appearance not intended by the manufacturer

Numerical execution and design variations make Royal Oak chronographs extremely attractive objects for collecting and research. In particular, rare specimens of watches from the early period of this collection appear on the market in which the original colour of some elements of the dial has changed, i.e., patinated. There are known examples with a patinated main colour of the dial, initially produced in matt silver or dark blue. We are very pleased to offer the present watch, featuring an extremely rare so-called tropical patina with the hour and minute hands having a light-cream tone. This rare colour change gives the watch an imposing appearance not intended by the manufacturer.

The watch case is fitted with screw-lock pushers and a screw-down crown, making it waterproof to a depth of 50 meters. The chronograph pushers are easy to unscrew and the requirement to apply smooth and pleasant pressure to activate the chronograph is a nice and very useful technical feature of caliber 2385 and its prototype Frédéric Piguet 1185.
