I also had a Tag Kirium when they first came out. It had pins instead of link screws. I was at a meeting and put my hands up in the air while making an important point and it fell off my wrist.
I also bought a blue faced stainless sub about 15 years before the white gold/blue dial sub came out. I returned to dealer for a black faced sub. That was my first rep and I bought from a Dr. that sold reps out of his office!
