Anthony Marquié

Anthony Marquié 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. His insight into the way this market functions make him a valuable consultant to several major brands and manufacturers.

Grégoire Rossier

Swiss national Grégoire Rossier is a biologist specializing in bionformatics. 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. This database reinforces the scientific approach that has guided this work.


Moonwatch Only, absolutely the finest guide to Speedmaster on the planet.


It is an indescribable reference work and a true must-have for every Speedmaster collector.


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.


The authors, a Swiss biologist and a French aeronautical engineer used their scientific skills to write what is certainly the most definitive work about the Speedmaster [...] They created a methodology which not only makes this book an important reference for Speedmaster collectors around the world, but also for future watch book writers who could use Moonwatch Only as a template for other important watches [...] Moonwatch Only is certainly one of the best books ever written about a single watch model.


A luxurious new tome detailing every model and attribute in the Speedmaster’s most famous lineage was a labour of love for its authors, and will be a bible for collectors.

QP Magazine

Moonwatch Only, released in 2014, set a new standard for watch-related publications and instantly skyrocketed to the number 1 position on the Speedmaster publications chart – should such a chart have existed.

Speedy Watches

In this book, Speedmaster fans will have a single source that has been created to answer all of the questions they might have about their favourite chronograph.


Several years in the making, this new book becomes the indisputable reference for all Omega Speedmaster models.


Actually, it is a true bible since it is made of around 500 pages full of information and technical data. But what I appreciated the most by browsing the book was its clever and sound organization.
