i purchased a swiss replica rolex submariner two tone 18k from zenith motors.com the watch did not have the serial and model numbers between the lugs.it also had a bogus certificate to match the watch.the watch also came damaged.something is loose inside the movement.i called them several times.they promised a replacement which i never received.they now will not return my phone calls or give me a refund.please stay away from these guys!i paid 950 dollars for this watch!347-429-****.also someone needs to check flawless watches.com i bought the same watch from them.it had no engravings between the lugs but supposed to be a true swiss grade one.i contacted them and they said all models dont come with the serial numbers and model numbers engraved.for 850 dollars i would hope so.
