need crown for asian 21j sub TTK/Andrew version

[chrono903]

so i receive one of those inexpensive subs from Neil and realize that the date window is just a bit off. Based on the price of the watch, i decided to take my hand at a fix. standing on the shoulders of giants i removed the case back with a rubber glove, depressed the little button to realease the crown, undid the movement holders, dropped the movement, popped the crystal, reintalled it, put the movement back in, which lined up perfectly now, i might add, and uh oh! The crown seemed to meet a bit of resistance. honestly, i did not conan the thing. i gingerly tried to coax it back in. well the tip broke off. am i screwed? are those crowns easy to find? anyone else have this problem?

thanks,

thom
