I just bought a Hirsch Viscount blue alligator strap for my Baume & Mercier, but some how the strap ended up on my Cannonball instead. The question is do I stick with the 20mm Hirsch buckle or should I purschase a 20mm Ball buckle? I also bought a roller buckle for the strap or should I stick with the roller? Would it bother anyone without having a Ball buckle on a Ball watch? Any advise would be really appreciated. Thanks!!
