Have a hard to rotate vintage sub/gmt bezel?

[sennheiserz]

I recently got a vintage 1680 Sub, and found it hard to rotate the bezel. It didn't seem stuck or damaged, just hard to turn. Since I use the bezel all the time, it was kind of a bummer.

I was googling to see what a full set for the 1680 looked like, and one had a picture depicting a card that came with it telling you about the 'Auto-lock' bezel. It is hard to make out, but the instructions say to push down on the bezel when rotating, as releasing it will make it harder to turn (locked). I just tried and it worked much easier!

Here is the image, its hard to make out: http://www.qualitytyme.net/images/wa...FS1132/set.jpg
