You might consider two things regarding the 36mm 29 that I personally don't think make the classic G10 size spec PRS-10 a good way to judge whether you'll like the former as to size:
> The old PRS-10's spec for case diameter @ 38.6 includes the crown; the new PRS-29A/AM spec for case diameter @ 36mm does not include the crown.
>> The old PRS-10's spec for lug-to-lug length is only 42.4mm; the new PRS-29A/AM spec for lug-to-lug length is a relatively quite long 46.8mm.
For what it's worth, I have the size equivalents of both the above in a 2006 C-Series RA pattern CWC G10 and an older version of the 29A, and, subjectively, but also very perceptibly, the classic and neat, but nonetheless stubby-lugged semi-helmet design of the great G10 wears much smaller for me than the beautifully long and slim 29A ---- I think the latter a very aesthetically special watch and a very different watch in comparison to a G10 spec PRS-10 regardless of these both having a similar east-to-west case diameter
