I have one to sell. And I was looking at some on eBay for comparison. Many have a number listed by it such as Omega Speedmaster Professional Moonwatch Men's Watch 311.30.42.30.01.005 Omega Speedmaster 311.30.42.30.01.005 Ss Black Letterboard 800000070113000 OMEGA Speedmaster Professional Moonwatch 311.30.42.30.01.006 Hand-winding_496770 What are these numbers. Are they on the movement?
Hi Kerry, the 14 digit number sequences are the reference number or PIC number (product indentifification code) They describe the model of watch, what the case is made from etc etc. I’m sure that if you google Omega reference number, or Omega PIC, all will be revealed. I forgot to add that the reference number for your watch is in your photo 145 022-69 ST
YOUR WATCH IS A GOOD ONE! Much different and much older than the other watches you note. Yours is late 1960's and likely the more coveted 861 calibre. These "pre-moon" versions bring good returns. You will like do very very well with it
