I'm looking to buy a nice leather strap for my vintage Hamilton, but the problem is the lug width is 15mm. It's a small and unusual size, and I was wondering if any of you guys had any recommendations? Aesthetically, I'm probably looking for a black calfskin strap with stitching surrounding the strap. Budget is $20-100. The most accessible options seem to be either Hirsch or Hadley Roma, but I've never bought a strap from them. Any suggestions? Thanks.
