I bought a vintage 70's Seiko automatic watch that did not come with a watchband. I bought a watchband on Amazon that did not come with pins so I had to buy these. I found a pair of pins for half this price but you get so much for only double price.  First is these are made in India so not the highest quality. I had to use the 19mm pins on the 18mm watchband. Only thing is that you will most likely not use most of these pins. Mens watches use 18mm to 24mm pins. This company should break down a set of small pins for kids & ladies & a set for mens.  I feel the springs in these could be a little firmer, in the future I am going to buy just a pair of pins & see if it is more solid & better quality.
