Notes
Audemars Piguet, “Royal Oak”, Ref. 5402
Launched in 1972 the “Royal Oak” Ref. 5402 was designed by Gérald Genta (1931-2011), four years before the “Nautilus” of Patek Philippe, also designed by him.
Nicknamed “Jumbo” by collectors, it owes this nickname to its “tonneau”-shaped case measuring 39 mm., who was very large for the time.
Avant-garde, it was the first all-steel watch considered a luxury watch, more expensive at the time than a dress-watch in precious metal. Another characteristic, its case is made of only two parts: the case-back and the case-band in a single part entirely maintained by the screwed octagonal bezel, allowing a perfect water-resistance.
Reference 5402 houses a version of the highly appreciated Jaeger-LeCoultre 920 movement, the ultra-thin AP 2121 calibre.
This reference has been produced in four series, marked:
· “A” (approximately 2 000 pieces);
· “B” (between 1 000 and 2 000 pieces);
· “C” and “D”, each of them with small modifications to the bracelet, dial and movement.

Where does the name “Royal Oak” come from?
--
Where does the name “Royal Oak” come from?
At a time when his enemies were in hot pursuit, the future King Charles II of England found refuge in a large hollow oak tree where he lay concealed for some time.
This “Royal Oak” came down in history as the symbol of a powerful force protecting a precious life: as in the case of the four vessels of the Royal Navy, launched in 1802, 1852, 1892 and 1914 that where named after it;
as in the case of our watch which conceals under its armoured case, the most valuable of mechanisms.
What over name could have been more suitable?
