suppster

Hello, I have bought a Rolex DateJust for a friend and the bracelet is too small to get over his hand. My dealer has quoted $10/link plus shipping and we have measured that he needs 10 extra links. Was the watch supplied with too few links? I have attached a picture, the DateJust is on the right and my Gen Tag on the left. Comparing to my gen Tag the strap is much smaller and when it is open the Tag bracelet is MUCH larger. $100+ for a $250 watch seems too much, what would people normally do in this situation? Thanks
