Excellent reporting.A few other observations on the Twill Jump after wearing it for a bit.
- It is definitely more supple than even later Jumping bands (and much more supple than the earlier Jumpings). I think the band is also slightly thinner.
- The Twill Jump is narrower at the lugs by about a mm compared to the Jumping bands. This might be a function of not having the diagonal line pattern woven in around the lugs on the Twill. The result is the band doesn't span the whole lug bar and can slide around a little during wear. It hasn't been a big enough issue that I have minded so far, but I wish it was the same width as the Jumping bands. This also makes the band appear almost too narrow for the S7-9 watch face. It's not quite there, but it's on the border. The width of the strap at the clasp is the same as the Jumpings.
- The Twill Jump has the same number of holes as the Jumping single tours. HOWEVER, the holes are moved up one space smaller on the Twill and are a much closer match to how the holes are punched on the leather bands. If you are someone who wears leather on the smallest hole and couldn't wear the Jumping bands because they were too big, you should be fine with the Twill Jump bands.

I‘m assuming the twill is thinner/more supple like the Casaque because it’s not stacking two colors like the Jumping and Toile?
