I've had post 1990 D links in steel, 1970s in 18k and 14k, USA oval 14k & ss models, and now a folded steel model from 1970...all with the standard classic clasp. The most modern D link had screws getting loose in the links...the oval seemed to stretch as you watched it...the gold were all nice but they all, gold or steel, suffered from clasps that popped open at the most awkward moments, and it seemed to happen when it slide down the wrist and then the hand moved in a certain way...like when doing push ups making a twisting motion.
The only exception to this is my current folded steel bracelet. This one has only done it once...when I was doing push ups and the watch had slid well down on the wrist and suddenly...pop and the bracelet came open. I had the same complaint about my Omega Speedmaster.
I don't like to wear a bracelet so tight I see it's imprint in my flesh when I take it off...and I don't wear it so loose that it dangles hookers' jewelry. Anyway...your thoughts and experiences with this issue, please.
I know that the extra lock on modern sub bracelets is supposed to cure the problem...but does it?
This is the current bracelet...folded steel.
