You are not the only one, mine was just the same. I lubed it with some sillicone grease the day I got it, but after 6 months of on and off wearing (which means setting the time & date a lot), the thread was worn out, and I wasn't able to secure the crown anymore.LUW said:[...]
What I don't like
When you turn the crown to hand wind things are rough, not faintly close to the smoothness of the 6R15. And also, the threads on the crown seem to be very coarse, because I have the impression I'm grinding metal whenever I loosen or tighten the crown.
I wonder if the material choice of the crown (or of the stem tube) was a smart one...
Sold the NY0054 as a bastler-watch.
I'll stick to NY0040's....
