I'm intrigued by the number of posts about folks returning their briefly worn watches to their AD for various reasons (one most recently because the bracelet clasp wasn't tight enough). Most of these seem to be in UK. What happens to these? The warranty card would've been dated at original purchase, so the next buyer of the watch would know it had been previously sold and returned, right? Or do they go back to Switzerland to be corrected and re-issued with a new warranty card?
