Hello, I've read numerous older threads on this topic and just can't seem to get a good answer to my question: I have the X Lume/ Glow on steel. I purchased the Ball rubber strap and I would really like a Ball deployant buckle to add to it. I've read and seen some pics of a Ball design that some have put on various ball watches. The Spacemaster rubber is 21mm, (I believe) but off course it tapers down at the end. I do realize that there are after market options. I do however want the steel finish to match. So is there a one available from Ball? If so how much? And how do I get it? And If I can't get a Ball buckle that fits, what's the best after market option? I asked my AD a while back and he didn't know..... Thanks IN ADVANCE Ballers!
