Personally, I like a pretty loose feel. I really hate the feeling of a watch sticking to my wrist so I like to be able to wiggle it and move it around quite easily if need be. I've been experimenting with my CrPO since I got it about a week ago. Over the course of a week, I first took out 4 links, bit tight, replaced one half link with full link, better but still a tiny bit tight, replaced the other half link with a full link and I think it feels just about perfect now. Allows my wrist to breathe a bit without being out of control or anything. Especially in this humidity with my sticky arms...
My current watches for my 6.5" wrist:
Omega CrPO 45mm: 12 full links + 2 full size clasp connection links
Omega SMP 300m 41mm: 9 full links + 1 third link + 2 half size clasp connection links
CrPO:
SMP 300m:
The SMP looks really loose based on that pic, but trust me it's not out of control. Also that's a lighter watch, about half as heavy as the CrPO so it really compensates for the extra looseness and doesn't make it a hassle. I keep the CrPO a bit tighter because it's heavy and not as tame, but it's still pretty loose as well. Love the feel of it since I last made it a tad looser.
I'm curious what everyone else prefers; post some pics of your bracelet/strap fit!
