True Story:
Years ago before I became a dealer I purchased a new Speedmaster Professional from Jomashop. It was advertised as the collectors box set but when I got it, it was a regular small box, the watch, and 2 nato straps and the strap changing tool - that's it! There is more to the Jomashop picture than low prices & warranty vs. no warranty. Moral & Ethics are in play and they have little of it.
I also purchased a Skyfall Aqua Terra from AuthenticWatches.com years back... it came with dust under the crystal. Long story short, 3 trips back and forth and they still couldn't get the dust out. When I asked for a refund it was a trial for sure because nothing was "defective" with the watch, lol.
I may seem like a grey market hater, especially given my position as a dealer - but I have personal experience with them and I'll tell you, they are straight up terrible. If you get a good watch and nothing goes wrong, and you plan on keeping that watch for life without ever selling it - sure you got a deal. But - if you ever do run into an issue or plan to re-sell the watch down the road - that is when the ugly GM side reveals itself. Everything comes at a cost.
I've learned just buy AD pieces... pay the extra few bucks from a trusted seller and live with piece of mind.
Just my opinion based on personal experience.
