Hi.. I have just added to my Heuer collection a 2446C. If I look at the reference tables and go to the images, my watch is identical in every detail to the example shown with the Tachymetre bezel, but is fitted with a minute/hour bezel. Can anybody confirm that both bezels were used on that particular example, please. The condition of the bezel is commensurate with the rest of the watch and does not, therefore, appear to have been retro-fitted. Many thanks in advance.. please keep up the good work!
