A couple of years ago I tried to source a 15202.
I was 'on the list' (fooly me) and patiently waited.
After I understood that it was not going to happen and I didn't want to pay the premium, I looked for alternatives.
But both the 15400 and the new 15500 seemed large to me. So I was after the 15300, which is very close to the original.
Today I managed to get one and I am deeply in love.
The design and the quality of the whole watch is indeed sublime. A keeper for sure.
