Tourneau is having a BIG sample sale, up to 70% off (so forget your cousin in the biz who could get you a "good" watch for 30% off). It started on Saturday, but you have until Thursday, the 20th to stock up on all those Jaeger LeCoultres and Vacherons that you've lusted after for so long. There will also be some estate pieces and some pre-owned timepieces. Hey, it's worth a look-see, for sure, even if your pockets aren't bulging with moolah, or watches, for that matter. Daily, from 9 a.m. to 6:30 p.m., at the usual Soiffer Haskin joint: 317 W. 33rd St., just west of Eighth Ave. Again, as usual, no children, no strollers, no cash (credit cards only), and come with time on your hands, so you can buy some more.
