The calibre 3120 has always been a very good engine – reliable, precise, nicely decorated.
The Royal Oak Selfwinding 41mm reference 15400 was launched in 2012 as an update of the reference 15300, the 39mm, automatic version of the Audemars Piguet Replica Watches Royal Oak – a watch that was a sort of sportier, more robust, more accessible, less hardcore version of the Royal Oak Jumbo Ultra-Thin, with a more classical automatic movement, a slightly thicker case and overall, a more mainstream take on the Royal Oak design.
This possible issue of the date window and a caseback with a movement too small for the case is now over, as Audemars Piguet has a new watch in the collection to replace the reference 15400. Fitted with a new movement, a new dial along with several other updates.
It measures 32mm in diameter, which certainly is more appropriate for modern-sized watches, including this 41mm AAA Audemars Piguet Replica Royal Oak Selfwinding. Compared to the previous calibre 3120, it displays several mechanical improvements. The frequency of the regulating organ is now 4Hz, compared to 3Hz in the past. The power reserve has been increased to 70 hours over the 60 hours for the former ref. 15400.
A New Dial
Updating the movement of a watch has consequences on the dial and the case. And this is true for this new Audemars Piguet Replica Royal Oak Selfwinding 41mm 15500ST. Again, while the overall design has been retained, multiple updates are to be seen on this watch.
This new reference 15500 still relies on the guilloché “Grande Tapisserie” pattern, with a delicate texture. However, even this has changed slightly. When looked at closely, you can sense that the proportions are different, the grooves are thinner than before, and the squares feel slightly larger.
An Almost Unaltered Case
The case keeps its 41mm Best Swiss Watches diameter and the same overall design. This means that we have the signature sharp case, an integrated bracelet and the octagonal bezel on top. The shapes, the finishing of all the surfaces and the proportions are all approximately the same as before.
The case is still water-resistant to 50 metres, and the crown is still screwed – making this watch more appropriate for daily use than the slightly more delicate 15202. This watch is slightly bolder and has more presence on the wrist.
