My precious: Chronostop Genéve ST 146.012/Cal 920. This Omega Chronostop is from 1969 (birth year), 41mm, and made for Italian market only. I got this one on my honeymoon trip to Vienna in 2005. I was there again recently and tried to find the shop (it was located close to the Opera) but unfortunately "Time Fair" is not on the market anymore. This Omega will never leave my collection. Please show your favorite Vintage Omega!
