Buckle Troubles

[Muttsta]

I recently picked up a PAM 111 and a strap for it from HKTAN. It is a hornback crocodile strap, so quite thick. I have the following buckle that came with it:

My problem is that I find the strap impossible to undo once I get it on. I've literally had to unscrew the strap off of my wrist because I simply cannot pull the metal pin out of the strap. I think the issue is that the strap is thick, and perhaps this is not the best buckle for it? Does anyone have any tips? It simply isn't wearable the way it is now

Nobody?

That can happen with thick strap. Are you able to flex it in the offending area of the strap?

Can you post a side profile pic of the strap?

Enlarge the holes one size and you should be fine. Any shoe repair place can do it.

Here are two quick iPhone photos. I am able to bend the strap in the offending area, with great difficulty, to undo the buckle. But definitely not while it is on my wrist. I am not sure how much each individual hole can be enlarged as they are fairly close together. I'm considering making these six holes, into three larger ones (combine two into one). Is this a good idea or no?
