We are an English language forum. You will get a far better response using English, even if you have to use Google Translator or another internet translation program, like I did above. Back to your question... Please look at these websites: https://www.omegawatches.com/en-us/watch-omega-other-omega-ck-2496 http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&2&2uswk&Omega_283 I think the caliber designated 283 began to be used in 1949, but it was known as cal. 30T2SC prior to 1949. Hope this helps, gatorcpa
