I've recently bought a Sub 300T Professional (with "boat" caseback ). It appears to be in good condition and keeps good time, however, the crown doesn't screw down. I wrote to Doxa, but they're out of any replacement parts, so now I'm here...
Thus, I'm looking for the crown and/or shaft. My (original) crown is signed, but I can live with unsigned one.
Thanks in advance for any information!
