c_a_mcleod Received my 24mm adaptor today and the watch fits perfectly in to the adaptor. The only concern I have is that the gap between the pin holes and the frame of the adaptor is quite small, so you can't really use more bulky straps styles. Over all though, I am pleased and will probably order a second adaptor when I get bored with the silver one I bought.
