@fitipaldi, thanks for the info and the pics, I just ordered a clasp to try it out.
You said you had to modd the strap that it would fit, could you explain what you did or what the problem is? I am ready to buy the APbands hornback, but I like this one a lot, the horn is longer and I bought from HKtan before, but it took a long time. So I will send him a mail to find out. Thanks a lot for sharing. Great looking watches, and they need to be on a hornback.....
