Smart move. One screw already broke, but I had no intention of using it again anyhow. I think the pin is a cleaver idea on the removal to replace a bad spring bar, etc. on a metal bracelet. I understand the concept. The compromise to the end links to make it work is something I could do without and would rather have a bracelet without the QR system. Give me drilled lugs and cut-out slots in the back of a bracelet any day.
Use QR pins on rubber and leather, but they add too much bulk in diameter on a bracelet end link design. Something has to be compromised to make the end link match the rest of the bracelet seamlessly. I think that compromise just weakens the whole structure of solidly securing the bracelet.
I think the quest to make everything under the sun EZ in the world we live in is out of control. Trying to make some of these clever gadgets can be counterproductive for those who enjoy the simple mechanics of the old things.
If something is a solid, time proven design, but too hard for someone to figure out or use, maybe they should find another hobby. Sometimes it's best to leave well enough alone.
