Not a lot a people share their knowledge anymore for free. Even though , probably i was never gonna make a watch strap , THANK YOU for sharing ...i might actually make one now.
I used both the Outlaw and the Boss...The Outlaw has a longer arm if you need the space .They are both great machines, easy to carry around , especially if you do shows. Great customer service from both companies
I had mine custom made , the o ring is about 1.5in and they are screw back . I used them exclusively for dog collars . Anyone with a machine shop can make them for you
