It's Speedy Tuesday! Earlier this year, Bert and I went on a horological trip to Switzerland and visited the OMEGA museum in Biel. One of the people from the museum showed us a number of Speedmasters that they had on archive (that is: not displayed in the museum). One of them was this very early Speedmaster 105.003 also known as the 3rd generation of Speedmaster pre-Professional model. We zoom into this OMEGA Speedmaster pre-Professional with reference number 105.003!
