Omega Speedmaster 145.022

hi, having sold my 3570.50 for a more vintage model, I have just acquired this little 145.022 which I have just presented to you 😀, according to the serial number which begins with 45581 it seems to me that it must date from 1984 on the other hand I am surprised not to have a logo on the glass and that there are a few years without this logo in the 80' if anyone has a glass with the logo😁
