·I inherited a Omega Speedmaster Professional and I cannot find a serial number of identify a year of manufacture. Band number 516 and an other number of 1039 at clasp. It is not running correctly and I would like to get it repaired. I can't and have no desire to remove the back. any help would be appreciated. see attached photo. I know the outer bezel must be missing. It runs about 10 seconds and then stops. Chronograph seems to be working erratic also but, is working.
