I have purchased a Bulova watch on Amazon.com
before and can tell you it's the real thing. HOWEVER, you must be careful when purchasing. There's products that are sold by Amazon and will say "Ships from and sold by Amazon.com
." You want to make sure you're looking for that when purchasing. There's also 3rd parties who sell similar products, which can be fake. I would stick with purchasing items from Amazon directly. That way, the product is real and if you have any issues, you could contact them and they'll fix it for you or refund you once you mail back the item. Even if they're being sold by someone else but is fulfilled by Amazon, it's not always 100%. At least with Amazon fulfilling, they'll still try to fix any issues you may have.
