Personally, I have not tried them but I have tried the wholesale outlet version for the non-chronograph. Due to my rep being 2824 instead of the 2892(gen) it was too thick for the rep case. So I would imagine if the Chronograph, being a 7750 in gen form, your chances are good if they have it available.
I am sorry, please excuse me. I have my first SMP Chrono, why would you change the crystal?
