From my personal experience, bracelets seem to vary in quality even within the same price bracket. Aesthetics aside, the build quality can be more or less objectively assessed in the following crude method:
1. with the watch on, look at the bracelet from the side view from a distance of about 6 inches. a bracelet engineered to a tight tolerance will not show gaps between the links. i.e. you cannot see your skin under the bracelet. A lesser bracelet will have visible gaps.
Somewhere between those 2 extremes:
2. the deployant also seem to vary quite a bit in the affordable price range. I don't know what is the optimal deployant configuration but I favor the single fold deployant secured with a metal nub.
the butterfly configuration is one common alternative design
Finally, I will just leave this observation out there. In the watches I own, one with the best bracelet can do this:
Watch "stands" on the bracelet when laid flat with the deployant closed.
The lesser bracelets seem to flop down.
I'm curious to see how this test to see if the watch can "stand" on its bracelet bears out with the higher end pieces.
