I went for this, a 39mm.
I'd been waiting for a 36mm 124270 from my local AD since it was released in 2021, but I got tired of waiting and bought something else. But the itch was still there however I wasn't willing to pay grey market prices for it so after a long time being tempted, I bought my first rep.
I was tempted with other models I could never actually afford, but I decided to go with what I wanted with the benefit of being a much simpler movement so less likely to go wrong and much cheaper to have serviced too.
I went for the 39 because I though the 36 was a little too small and the 40 too big, and I kind of wish I'd stuck to the 36 but still. I was really impressed with it too, having handled the genuine article a few times it's difficult to tell the difference!
