I purchased a Tissot watch (Seastar Automatic) from Amsterdam Diamond Center, only to find that the damn watch was faulty. Its power reserve was faulty, i think, given that it would stop working after 5 hours off-wrist. When i contacted them after 2 days, they said the only option is to ship the watch back to Tissot, get it repaired, and get it shipped back to them and that i shd check in 1 month!!! This was totally outrageous, given the 2 yrs guarantee on a brand new product. Why could they not replace it? Who would allow to spend such money on a brand new Tissot and then it gets repaired the next week??? I THINK they sold me a fake Tissot product and I am prepared to take all the action there is (legal) against them. I have already contacted Tissot and I am totally dissapointed with ADC. All buyers, beware, Amsterdam Diamoind Center sells fake stuff.
