Bought my Apollo 11 45th from them. Being a grey dealer they sourced it from a mainland EU dealer - they estimated 3 weeks and it was only a little over that in the end. My only criticism would be that their comms were weak during the waiting period, but like I said, they came good, which is what matters.
Never used them. For some brands they are cheaper than high street. Rolex discount is minimal. And, they are showing nearly £3500 for a tudor black bay bronze. Mine from Goldsmiths last week was £2730. So, like all these things know the real retail and go from there. As for their service, they appear to get great reviews. They don't touch JLC and Cartier.
I bought a Breguet from Iconic. Perfectly handled transaction and arrived within the stated three weeks.
Thought I would report back on my experience with iconic watches. Very friendly, very good communication l, very impressed!
