Audemars Piguet, “Répétition Minutes Tourbillon” with Cal. 2872 The Ref. 25858, with the Cal. 2872 (minute-repeater with one-minute tourbillon regulator), fitted in a round shaped-case (Ø 39 mm.), was produced between 1996 and 2001 at only 14 examples and sold between 1997 and 2002, with different materials cases: • 5 examples in 18K pink gold; • 4 examples 18K white gold; • 5 examples in platinum. The Ref. 25937, with the same calibre and horological functions, fitted in a round shaped-case (Ø 39 mm.), was produced in 1998 at only 5 examples and sold between 1999 and 2000, in a fully diamond-set 18K white gold case with diamond-set dial and diamond-set bracelet. The Ref. 25982, with the same calibre and horological functions, fitted in a “Jules Audemars” shaped-case (Ø 40 mm.), was produced in 2001 as a unique piece and sold the same year, in a diamond-set 18K white gold case. Audemars Piguet Cal. 2872 The Cal. 2890 was produced until 1996 and 2001 in 20 examples only and was fitted in different reference case numbers (see above). … and after 2000 ? It appears nowadays that Audemars Piguet has still produced a few references 25858, “Répétition Minutes Tourbillon”, with Cal. 2872, at the binging of the 2000’s. After 2001-2002, the exact information is missing as it is not published in the latest edition of the Manufacture book dedicated to complicated wristwatches (see bibliography). The present Ref. 25858 was probably produced after 2001 and was sold in 2004. Its mother-of-pearl dial with spherical globe-like design and large luminescent Arabic numerals is incredibly modern and makes it absolutely irresistible! Unfortunately, we don’t know exactly how much of this model was produced, but we can easily imagine that only a few pieces were taken from the workshops of the Vallée de Joux factory.
