GMT Donut
can someone tell me whether or not the GMT Master II bezel clicks when turned the same as a submariner or DSSD ?

It clicks, but not as loud as my SD.

It should click, but as Joe said, not as discernible as a Sub/SD bezel.
and each GMT reference should click differently. 1675/ 16750/16700/16710 have a lot of clicks (120?). I believe the II-c should have 24. The earlier ones (bakelites) need to be pushed down and then rotated, so I guess, no clicks. Hope this helps.

Click is accomplished by an arc spring. If u ever replace or adjust the insert yourself, you'll see what causes the click.

Older acryllics used a slip ring friction fit--non clicking, but again bi-directional. |

GMT's, Sub's, and SD's all use a 120 click bezel mechanism. It consists of teeth in the bezel that "click" over a spring that resembles a straighened paperclip
On the Sub and SD, the "spring" is straight and so it catches when trying to turn the bezel backwards - therefore thay are uni-directional. The GMT uses a spring with a bend (like a shepards crook) at the end, and therefore, it does not catch with rotating the bezel backwards and it then bi-directional... As Mike pointed out.... the ceramics use a completely different, more sophisticated system of springs, ball bearings, bearing races etc...and are not related at all in the GMT to the Sub.. The spring..
