Query: the bible of buyer's guide watches

We have been very pleased with all three issues of "Watches". The magazine is well designed and provides a wealth of information on watches and movements. Most of the major luxury brands are represented providing companies' background histories. The magazines serve us well as reference guides, as well as, sales tools. "Watches" have had a great success with out clients, many of who are avid watch collectors
