Check out this thread which might help with a solution with using the '57 flat link bracelet and the US end links.
It's essentially a half link adjustment. They added a lot of complexity, a longer clasp and more cost for not much range, but the market insisted on it. Cue the old school EW321 bracelet, two holes with the same half link adjustment, easily adjustable with a toothpick or paper clip. Once sized I don't need to adjust a bracelet, but some seem to be changing it constantly. Give me simplicity.
I find I adjust mine between the second position and a third I added, pretty regularly. But, it's not hard to adjust and I'm fine with it
I’m just tipping my toe into the modern Speedmaster venue from vintage, and don’t have experience with these new bracelets, so let me see if I’ve got this right: on bracelets like the ones on the New Ed White and new FIOS, there are no half links? But the both the holes in the Ed White clasp, and the on the fly adjustment are half links. So this explains why you regularly go from position two to three, rather than add a half link, which would allow you do go between position one and two, which are original to the bracelet?
