I bought an Omega Speedmaster Professional from Caliberswiss (Greg) and the entire transaction was fantastic. Aside from the great, grey market-like pricing for a BNIB Moonwatch with AD stamped 5-year warranty, the package was shipped quickly and more securely than anything else I've ever ordered. He was quick to reply to my questions via email as well. Overall it was a great buying experience. The next time I'm in the market for a watch of this caliber (no pun intended), Greg will be one of the first sellers I check in with.
