The steel version accounts for 80% of the total production of Model 25770 model (excluding blackened PVD-treated steel). While the first year’s results were modest with just 73 watches sold, deliveries then increased regularly to reach an annual average of 303 watches between 1998 and 2004.

The archives do not permit us to determine the number of watches produced in colour, but they document seven variants: yellow, orange, brown, red, green, violet and turquoise. Oral sources tell us that they were created as one-offs to adorn a showcase celebrating the 25th anniversary of the Royal Oak (1997) and that they were so successful that Audemars Piguet decided to launch them into series production. Two of them were even published in the brand's catalogue:, the red variant in 1998 and the yellow from 1998 to 2002.

Sales from 1996 to 2016: a total of 2394 units, of which 73 (1996), 186 (1997), 319 (1998), 367 (1999), 289 (2000), 305 (2001), 199 (2002), 375 (2003), 272 (2004), 5 (2005) 3 (2012) and 1 (2016).
