Hi all, First off, thanks for all the contributions to this forum. The wealth of information you’ve gathered is a great resource. I’m new to vintage Omega ownership, having just received this 18k Cal. 343 chronometre from my wife for Father’s Day. Wow! Here are the pics. So, having poked around here, I was super interested to find on the forum that Rick42650 has the twin to my watch from the thread below: https://omegaforums.net/threads/343-rg-chronometer-case-correct-or.35536/ My case has the same British hallmarks as his, but with number 102, to his 104. The serial numbers of our movements are only 4 apart, as well. Separated at birth!
Your wife gave you a 343 Chronometre? Welcome, and please send me a PM should any signs of a possible divorce appear...
