Here is a great link to have saved. It is the official Omega vintage watch page/pages from their U.S. website. It's a priceless resource with reference numbers, images, and other info about these vintage Omega watches that we love so much. Vintage Watches | OMEGA US® (omegawatches.com)

What a beautiful watch! Very elegant but subdued and practical at the same time. I think blue watch faces and bezels are irresistible to look at.
