Lot essay

In 1989–1990, Audemars Piguet created their first Dual Time wristwatch – Ref. 25685 – with a classical round design in 18k yellow gold, displaying the time in a second time zone. It was produced on the basis of the self-winding caliber 2229/2845, which had been developed by the brand based on an ebauche caliber 928 supplied by Jaeger-LeCoultre, long-term partner and supplier of Audemars Piguet. Reference 25730 is the first Royal Oak Dual Time model embedded with this caliber and the additional functions of a second time zone indication in hours and minutes, power reserve, and date on a sub-dial. During its production span, Ref. 25730 was available in different variations and was mostly produced in stainless steel. Some examples, however, were produced in stainless steel and yellow gold (Ref. 25730SA), stainless steel and tantalum (Ref. 25730TT), platinum (Ref. 25730PT), and in 18k yellow gold (Ref. 25730BA). Several dial colour options were also offered, while the dial design changed during this period – according to our knowledge, there were at least four generations of Ref. 25730 dials.

In 1989–1990, Audemars Piguet created their first Dual Time wristwatch – Ref. 25685 – with a classical round design in 18k yellow gold, displaying the time in a second time zone.

The present lot features the second-generation matt silvered dial, with its characteristic original small ‘Grande Tapisserie’ pattern, applied “AP” index at 12 o’clock, the modern version of the logo printed over the ‘Grande Tapisserie’ pattern just below the “AP” index, classic Royal Oak rounded baton indexes, and a power reserve scale with Arabic numerals up to 36. The other features of the present example are a stainless steel ‘pre-AP’ double-folding clasp, and a crown signed with an engraved “AP”.
