Purchased a BB36 from watchfinder and when I phoned up to arrange delivery the woman asked if I would like the bracelet sized for my wrist to which I agreed, expecting to receive a properly sized watch with a couple of spare links in the box.
The watch arrived, too tight for my wrist and no spare links so I contacted my salesman (Tom) only to be told that the watch would have gone out with the same links and accessories as they received it, there had been no mention up until that point that the watch did not come with a full set of links. At the time I shrugged it off and made my way in to Rolex St James and bought a couple of links which they fitted FOC.
Having read this thread it sounds like this is an all too common occurrence.
