Audemars Piguet Royal Oak Offshore Chronograph 25721ST "The Beast" (1997)

*Serial D*

Pre-owned Audemars Piguet Royal Oak Offshore Chronograph Ref. 25721ST.OO.1000ST.01, with a 42mm steel case, steel bezel with 8 visible screws, dark blue Therban (rubber-like elastomer material) clad pushpieces and screw-locked crown, steel pushpiece guards. Internal bezel with tachymetric scale, dark blue dial with "Clous de Paris Petite Tapisserie" pattern, white gold applied indices and Royal Oak hands with luminescent coating (Tritium). 3 white sub-dials: 12-hour counter at 6 o'clock, 30-minute counter at 9 o'clock and small second at 12 o'clock, date display at 3 o'clock (through "Cyclops" window). Glareproofed sapphire crystal and solid case back. Automatic movement calibre 2226/2840. Steel bracelet with double AP folding clasp.

The first Ref. 25721ST, also nicknamed "The Beast" due to its staggering proportions, was far ahead of its time. A huge and thick case, measuring approximately 16mm in height. The Royal Oak Offshore Ref. 25721ST starts as D-series. The production of the D-series Audemars Piguet watches start in 1992 already, but the Royal Oak Offshore is delivered to the market in 1993. The first serial number of "The Beast" is D23744 and the last watch is the D97184. The last D-series was produced in 1998. In that time Audemars Piguet produced 1300 reference 25721ST watches in the D-series. All these watches came up in smaller batches (200-100-200-300-200-100-200), adding up to exactly 1300 pieces.

After the first 200 watches, Audemars Piguet started to use the calibre 2226/2840 (instead of the 2126/2840) for the Royal Oak Offshore, which was based on the Jaeger-LeCoultre 889/1 with a Dubois-Depraz chronograph module. Combined with the heavy stainless steel bracelet, the watch weigh approximately 223gr. On the D-series the links of the bracelet have 4 screws - 2 on both sides (on later models that has been reduced to 2 screws- 1 on each side). Besides a very visible gasket below the octagonal bezel, there are also rubber (like) pushers and crown. This material is actually referred to as Therban, a high-performance elastomer that is resistant to extreme temperatures. This material was developed by Bayer in 1975 and marketed as Therban in 1986. The Therban pushers and crown have the same blue tone as the dial.

In mint condition. With original box, travel case, register extract and full service card with warranty until July 2023.

Read more about this watch...

In 1970, Audemars Piguet instructed Gerald Genta to come up with an unprecedented steel watch. As the story tells, he found inspiration whilst seeing a diver at work with an old-fashioned diver's helmet near lake Geneva. Genta drew the design of a circular case with an angular, octagonal bezel, 8 visible screws, and an integrated bracelet. The Royal Oak was presented in 1972 as the most expensive steel watch available and it caused an uproar: why was a distinguished maison d'horlogerie puttin out a sports watch in such an ordinerary material? Some expertest even predicted that the Royal Oak would put Audemars Piguet out of business.

The Offshore is based on Gerald Genta's Royal Oak design but was modified by Emmanuel Gueit when he had the age of 22 years. Initially, most people didn't like it. Genta even invaded the booth at Basel World 1993 denouncing that his original Royak Oak had been destroyed by Gueit. The name "Offshore" doesn't appear on the watch at first, as Audemars Piguet is not entirely comfortable with it yet. The first 100 Audemars Piguet Royal Oak Offshore models only bear the name "Royal Oak" in the case back. Starting number 101, they have "Royal Oak Offshore" engraved.
