It's a pretty limited sizing quick adjust, but everyone I've assisted in ordering the comfort kit conversion clasp has reported they are glad they did.

 

I've watched a lot of your Youtube videos, good sir!

 

Ajustement is the same on the new clasp. Just 2 positions and same variation in length. You just get the ease of the push button.

 

Maybe try a piece or two of moleskin on the case back to act as a "shin"?

I do this when I get one of this with an "in between" size issue.

 

Move one link from 12 to 6 side of the clasp or vice versa. It will make the bracelet wear tighter or looser (you have to experiment with it).

 

I bought the bracelet a couple of weeks ago. I think you will like it. I'm pretty picky on how my bracelet fits. I don't want the watch head to move much when my hand/arm is in motion. As a result, it can be too tight when my wrist swells up.

The adjustment requires more force/not as smooth as the Seamaster 300M Diver and the new Tudor T-Fit system in my experience though. You have to really push down while making the adjustment.
