Clavi, this etrier is nice and I would not hesitate one second to wear such a nice watch.
Your question rings like a challenge. Please note that I am ready to go to even smaller and older watches!-)
Recently, I had the chance to see a jaeger duoplan, a very very small watch with a beatiful black dial and an amazing half cylinder glass. Even if the watch was very small - even too small for women under modern criteria - I was tempted by this vintage jaeger. Not the kind of watch I could wear every day ( as a memovox or a futurematic), but for a special occasion, it could be suitable.
No photo of that duoplan yet, but I will try to take one and post it here. The small size of the watch makes me bet that this duoplan may remain a long time in the showcase.
Have a nice sunday!
