Big congrats mate !
the 15300 is a true gem !
I went thru exactly the same path as you.
Couldn’t get the 15202 ... waited and waited.
15400 too big ...
Eventually I managed to find a blue dial 15300 in mint condition just few months back and I got it. Yes it’s a big premium over their original prices even for the blue dial 15300 now but still a bargain over the blue dial 15202 !
Most importantly is to enjoy our 15300s.
Big congrats once again and enjoy in the best of health.
