Yes, last August, when I bought the grey strap from the PP Salon, I ordered this black one, which was my first idea.
When it arrived in October, I had it installed and, because changing the strap with these screwed lugs is a nightmare, it's "impossible" for me to revert to the grey one on my own. I have to wait until my next stay in Paris if I want to.
Ideally, I'd love to be able to change more often, but the only time I unstrapped the watch myself I decided I would never do it again and let the PP watchmakers do the job safely!
Best, Emmanuel
