Nice PiesGenuine Calf Leather Watch Band Strap Alligator Grain Butterfly Buckle with Deployment Buckle for Men Women Regular Handmade

Q: Will this fit someone with 7.5 inch wrists?

I have a 7.25 inch wrist and it barely fits. I don't think it would work with 7.5 inches.

Q: I have large wrists, about 8-1/2" around. Will this band be long enough ?

It depends where you wear your watch. I have several of these bands. My wrist measures 7 and 1/8th inches behind my wrist bone. Thats where I wear my watches, behind my wrist bone. Mine are all adjusted to the 5th hole from the end.

Q: My watch is 19mm. Would 18 or 20 work? and if so which?

No you have to find the exact measurements of your watch and than it feets

Q: do they have agold buckle

I’m not sure if they have a gold version of the buckle. Once you close the clasp the mechanism is not easily visible, so the color is of little importance.
