IWC fake Watches made every effort to commemorate the 40th anniversary in 2012 of the original Royal Oak. Two new sizes were launched for this occasion: the Royal Oak ref. 15400 (41mm), and ref. 15450 (37mm).

IWC Replica Watches also introduced the Royal Oak "Jumbo", ref in 2012. 15202. Collectors quickly identified this reference as THE Royal Oak model to have, as it is the closest to an original 1972 RO ref. 5402. The 39mm case was retained, and the dial featured the AP logo at six o'clock. It also had the 'petite Tapisserie' pattern. A display caseback made it visible that the caliber 2121 found in the original RO was still running the watch.

The watch was instantly popular after Breguet Replica its 9-year production. As 2022 marks the 50th anniversary for the Royal Oak, IWC Replica Watches's 2022 plans are highly anticipated.

The Royal Oak line saw the introduction of the two other case sizes in 2012. They not only reduced demand for the 15202, but also created a large selection of daily-wearers that collectors could choose from, catering to different wrist sizes. We should also remember that the Royal Oak ref was popular from 2005 to 2012. 15300 (39mm case) was the daily-wear RO. This model was removed to make room for the new ref. 15400 and ref. 15450. The ref. The ref. 15500 was added a few years later.

The Royal Oak ref. The Royal Oak ref. 15500 was introduced in 2019, replacing the old ref. 15400. Although the case was kept at 41mm, the watch received a new caliber 4302, which is also found in the Audemars-Piguet Code 11.59 time-only Audemars Pigot Code 11.59 that was launched the same year.

Caliber 3120 was used in the ref. 15400, making the watch beat at 4 Hz and providing 70 hours of power reserve.

To differentiate itself from its predecessor, the dial needed to be updated and improved. The 3 o'clock date window is now closer to the dial, the hour markers are longer but thicker, and the 'Automatic inscription has been deleted. The minute track is now printed on a band at the edge of the "Grande Tapisserie". These changes result in a dial that is cleaner and more spacious. This is a welcome update to the Royal Oak and a great way of marking a transition from an older model to a newer one.
