I have an incoming watch that takes a 26mm strap. Not having any on hand and knowing that I'd need an XL I asked around and folks suggested WUS's own sponsor Panatime.Com.
Took a look and found a nice black 26mm Soft German Calf Radiomir Style Taper that I liked an ordered it. Arrived 2 business days later from Joe at Panatime via USPS.
I also ordered a very nice 26mm Brown Croco Leather strap in XL that was only $12.99!
Good service, good prices, nice merchandise!
