As per Audemars Piguet Heritage Calibre 2003SQ:

‘In 1970, on the eve of the quartz crisis, Audemars Piguet decided to openwork this ultra-thin mechanism. For the occasion, the Manufacture chose bridges and plates in 14-carat gold. It took 5 years to complete the first 250 pieces. The operation demanded skill, know-how and patience: for the best artisans, this meant almost a week of work at the bench for a single movement. Success followed: more than 1,000 watches were produced in the 1970s, 400 in the following decade and 1,660 in the 1990s. In just over a quarter of a century, 3,460 Calibre 2003 blanks were purchased by Audemars Piguet for openworking.

Calibre 2003SQ equipped ten Royal Oak models (30 mm and 33 mm) between 1992 and 2000, for a total of 256 watches. Reference 14794 alone accounted for 60% of production. If we add the 25% of Model 14882, we understand why the other interpretations were manufactured in very small quantity, 10 units or less. Each one of these watches is a masterpiece of watchmaking, miniaturisation and often jewellery.

It is worth noting that Calibre 2003SQ was often fitted with gemset hands. However, once set, a hand becomes very heavy. Only a sufficiently powerful calibre can ensure its perfect rotation.’
