Can anyone tell me about this model? I acquired it recently from a reputable auction in the UK. I believe it is dated at around 1990. It has a 1140 movement and keeps very good time. It is unusual in that the back case has the omega symbol and the word OMEGA under, but not the usual badge and no ref number. It is in very good visual condition with virtually no scratches on case, face or bracelet. Unfortunately yesterday the start/stop pusher fell off, but I understand this is an easy repair though necessitating removal from the case. Thanks, John (PS my other watch is a JLC Reverso that I have had for 15 years!)
Looks to be a speedy reduced ie automatic version. Not sure about case back, should find out more if you research Speedmaster reduced or automatic.
