The cargo arrived later than I expected. There was no difference between rolex original box vs fake and the watch can be considered good quality. thx

Shipper has been very accommodating, responsive, friendly, and selfless. Seller even upgraded to express shipment at no charge knowing that the watches purchased with FedEx. Seller immediately sent out and replaced my order and managed to get order out to me on west coast USA in timely manner. The watches are perfect, no issues whatsoever. Everything was aligned, very accurate and aligned with description. Buy with confidence!

I picked the dark outlined variant of this model and it coordinated very well with every one of my outfits. The 40mm bezel fits completely on my wrist. I prescribe the people who wonder whether or not to get it automatically it merits purchasing a reproduction watch!

sabren
At the cost this is a phenomenal watch. Just minor issue I have is the dial is very somewhat slanted counterclockwise. Yet, you'd just notification on a nearby assessment and at the cost I look at that as a success
