I have a mint condition omega brown alligator strap. It is 22x18. I wore it for about 10 minutes and decided I liked my watch better on my blue cordura strap. It is a flat at the lugs so will fit any 22mm watch. It will also fit a 21mm. My watch is 21mm and it fit fine. Price $180 shipped in the us. I am open to shipping internationally but would need to get a shipping quote. Pic on my watch are just for reference and watch is not for sale
