EDIT - Actually 19mm would be better. Title and post updated. Looking for an original vintage 19mm Tropic strap in the silver/grey color. Straight ends only please. Might also consider a Tropic Star, but not the Tropic Sport. Let me know if you have one you'd let go of. I also have many bracelets/bands to trade if interested. Other Tropic sizes, etc. Thanks in advance!
