Hadley Roma 22 mm genuine alligator black watch strap, model 2018. One fixed keeper and stainless steel buckle. It is rather thick and too thick for my dress watch. Not stamped leather; this is genuine alligator. 22 mm at the lugs and 22 mm at the buckle. It looks new; worn only twice. Retail is well over $200.
I also have many other straps (new) and deployant clasps, which are unused. Most from name brands (not generic) and new; priced from $3 to $20. All 22 mm.
