Gerard, these pictures are gorgeous, and the watch is sublime. I love the 5247 Chrono so much that it is on my list. In white gold.
It has a lot of charm in rose gold. It enhances its vintage look.
So, manual winding movement, and a nice one, plus an enamel dial... Two good reasons to have it.
As you said, 39 mm is a maximum.
I really like it.
Thanks for your post. You should post more often!
All the best,
