For sale, I have an Omega Constellation Electronic Chronometer Ref: 198.741 $400. It has the Caliber 1250 which is an electronic movement. Case measure 37mm without the crown. Watch has a new battery and is working fine. The date wheel works and changes automatically. It has a very sharp case. The serial number would suggest the watch is from 1972. The watch will come on a leather strap. I’m asking $400 USD for this watch which does not include shipping. Accepted payment methods are wire transfer, Paypal, or Crypto. Watch is located in Toronto. I will offer a return if I have made any major mistakes in my description of the watch. Below are some references from the forum.
