Why not Glidelock on every model?

[TheVTCGuy]

I have had my GMT for a couple days, honestly, I like it much more then I thought I ever would. I adored my 126610 sub, but my 126710 just seems to have a bit… More. I will do a comparison after wearing this one for a month, the pros and cons of the Sub and the GMT but I can tell you right off the bat one thing I REALLY miss is the Glidelock function of the Sub.

Maybe I am weird (well, I AM, but that’s a story for another thread) but I was subconsciously adjusting my Glidelock. I guess I have sensitive wrists… Anyway, it is a big adjustment trying to get used to the +- 5 MM only adjustment on my GMT clasp. I can just not seem to get it right I have ordered a half-link from Rolex, hopefully that will give me the Goldi-lox fit, but there is just nothing compared to the very convenient 2mm adjustments of the Glidelock on the Sub. So, my question is…

Why can’t Rolex include this feature on all models?

Or do I just have weird wrists that expand and contract more then normal?
