"flimsy" Rolex bracelets
To get the light feel of the bracelets, you want to consider the older ones called "folded". Rolex stopped making them in 1980...
Following that, the 2nd best is anything pre SEL (solid end link), that is anything before circa 2000 .
I would also consider Explorer 2 and GMT bracelets. they are the same with shorter clasp, wears better.
bracelet models to fit the above includes: 9315, 9316, 7836,
78360, 93150, 93160,
Last, almost anything pre ceramic (6 numbers reference) is a mix and match. Older models' bracelet (20mm) will fit newer watches watches. for example :1985 bracelet will fit 2003 submariner as the bracelet end link is what's important.
Good luck
