The blue dial looks great, with the contrasting white accents and red second hand.
I recently saw a mens stainless steel dynamic from early 70's at a local watch service centre, which also has some lovely pre owned watches. It has a black dial, no date, and a red second hand. Manual wind and very good working order as well.
Thanks for the photos of the change from the strap to steel bracelet. Nice job on the change. Very interesting to see how the bracelet integrates with the case. They did the same at the shop on the Dynamic I saw. They found a NOS bracelet and replaced the old black strap, which was also in good condition. It gives the watch a totally different look.
I may go back to the shop this week and see if they still have the watch. Your thread has really been an ispiration to me.
Cheers,
Carl
