Query: Absolutely terrible - stay away from Amazon

- Watch does not keep time- It came with no authenticity certificate and is most likely fake- Return to Amazon failed. Was trying to ship back from Canada to US and it would not pass thru customs due to the wrong RMA number (provided by Amazon)- Spoke with a dozen customer service reps and their managers - all were useless.- I am stack with a brick and Amazon has $2300 of my money. In the process of calling my lawyer. Do yourself a favor. If you are on the market for a high end watch, negotiate a 20% discount with your local dealer. Do not deal with Amazon, unless you want to be abused and deal with a retailer that takes zero accountability for their merchandise.
