Anthony Marquie is a French national and a trained aeronautical engineer. He swiftly turned to an international career in finance and investments. He has always been a collector of both modern and vintage watches, including many icons from the Omega production. Today he spends a lot of his time looking for rare examples, as well as studying the market for prestigious watches and collector's pieces. Gregoire Rossier is a Swiss biologist specialising in bioinformatics. He became a watch enthusiast at the age of 13 when he inherited his first Omega Seamaster, but it was only much later that he started serious research on the Moonwatch. Applying his experience as a researcher, he developed a systematic database of thousands of entries referencing all his observations as well as the market trends for several versions of the Speedmaster.
"Moonwatch Only is certainly one of the best books ever written about a single watch model." - William Massena - Timezone.com. "It is an indescribable reference work and a true must-have for every Speedmaster collector." - Forbes. "This book sets a new standard. Not only for books on the Omega Speedmaster, but for watch books in general. I've never seen anything like it, and believe me when I tell you that I could fill an impressive sized wall with books on watches. Authors of other books or publishers should take a look at Moonwatch Only as well to see how it should be done." - Robert Jan Broer, FratelloWatches. "The OMEGA Speedmaster Professional - the Moonwatch - has done things that no other timepiece has done and it's been worn in places that only a few human beings have been." - Captain Eugene Cernan, 'Last man on the moon'. "This book is a no-brainer still. It is the most complete work on the Speedmaster in print that is available." -- Fratello Magazine.
