I purchased this watch for my wife in September 2011. It was shipped by Perfect Timing, an Amazon.com supplier. In March 2012, the back panel of the watch detached itself from the watch and the watch stopped working. We filed a report to Perfect Timing, asking them to repair the watch under the 30 months warranty that was provided with the watch. We received from Perfect Timing rejecting the claim and wording of their one line response was rude. We are still trying to solve the problem with Amazon. com, but so far they have not been very helpful.So, beware when you purchase an expensive product from Amazon.com if the shipment is done by an outside supplier.Unless you are talented in the repair of watched, my advice would be to stay away from Perfect Timing,
