Notes

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 Genta.
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.

--

Purchased new by the owner in 1976, this watch has been maintained regularly over the years but more importantly he paid careful attention to keeping the original warranty and instruction booklet rarely found today.
