15500ST or 15510ST: what actually differs?
In this build, less than the number of forum threads suggests. Both are the 41mm octagonal Royal Oak. Both run the same integrated cal.4302 clone. Both are the same price. The difference you can actually act on is which dials each reference comes in.
What is the same on both?
The case, at 41mm across and 10.5mm thick, brushed and polished on the facets, held by eight hexagonal screws. The bracelet, integrated and tapering to a folding clasp. The movement: an integrated cal.4302 clone built by the Dandong movement factory, free-sprung balance with eight weight screws. And the price: $1,110 either way, which is the watch on its bracelet.
What actually differs between them?
The 15510ST is the one with the wider choice in our range: blue Tapisserie, black, khaki green, grey and silver. The 15500ST comes in the blue Tapisserie and grey. If you have settled on khaki green there is no decision to make, because that dial belongs to the 15510ST here.
How do I pick between them?
Pick the dial first, then the reference follows. If the dial you want is made in both, there is no technical argument for either one in our build, because the case and the movement do not change. Choose by the dial you will look at every day, not by the reference number.
What do you not claim about either one?
We do not claim to reproduce every production change the two references went through in the real line, and we publish no water-resistance rating for either. What we can show is the specific watch you are buying, photographed after the order is settled and before it ships.
Is one of them a better movement?
No. Both run the same integrated cal.4302 clone with a free-sprung balance, from the same movement factory.
Which one has the khaki green dial?
The 15510ST. Khaki green is listed under the 15510ST only.
Are they the same price?
Yes. Both are $1,110 for the watch on its bracelet. Shipping is a flat $50, and box and papers add $100 if you want them.
