The D-21 Saga watch can be seen in an ad from Life magazine dated 16th Aug 1948. I suspect the model name is derived from the D model with a M21 movement.
Hi, My name is Mark Rushworth AKA Timetrope on Social Media. Ive been collecting Timex watches for a little over three years. From day one the community of collectors have been very patient and generous for the most part which has kept my interest and engagement in the hobby.
'Ive set up this website partly as a way of cataloging my collection and its many gaps, and as a way of paying forwards the kindness offered to me by Knut, Ian and others (you know who you are).
