Strap has been worn about 10 times in rotation, great condition, still has lots of life left. 19 mm at the lug, 18 mm at the buckle. Length: 120 mm x 80 mm. Buckle is polished stainless steel and is signed by DiModell. Strap only, no spring bars. The duke is extremely versatile and looks great on dressy or sportier pieces. I paid $45 for this strap. Selling for $30 pay pal and USPS shipped. ConUS only. Thanks!
