Three years prior, two men decided to launch a book which provided an unprecedented level of data, entirely focussed on a notorious watch. Their names: Grégoire Rossier and Anthony Marquié. The watch in question: The Omega Speedmaster “Moonwatch”. The book: Moonwatch Only . This example of an encyclopedia quickly became the ultimate reference guide for Speedmaster lovers. It explored all the models, all the components were dissected and it additionally included multiple recorded references… It was a true “Moonwatch Bible”. Today, the Speedmaster Guide is back, this time in an electronic version, named E-Moonwatch Only ( available on iBooks ), and it features a new instrument that will make life easier for collectors.

While the Moonwatch Only book is a heavy and thick 566-page reference guide, divided into several sections (with exhaustive foundation and history), the mobile/electronic version, E-Moonwatch Only, promises to be lighter and more functional – and fear not, despite the fact that it is more budget friendly than the book (EUR 29,99/US$ 32,99 when the book is EUR 250,00), this doesn’t mean that this iBooks version of Moonwatch Only is poor. A long way from it! However, its purpose is marginally different, as it very well may be described as a traveler’s guide – and because it’s on iBooks, it very well may be read on iPhones, iPads and Mac.

E-Moonwatch Only does not contain all the details or verifiable data gathered into the first book. Instead its specific center is towards model identification, which is a key factor when searching for a Speedmaster. It includes all references, models and key components of the Speedmaster, just as an identification apparatus. Why? Imagine you are enjoying an occasion on the Amalfitan Coast. You pass before a vintage watch dealer and in the showcase window, you notice a superb looking Speedmaster CK2998… But, how might you be sure in under 5 minutes that this model is legit?… E-Moonwatch Only can help you. Above all, what’s inside?


Just like the print version, E-Moonwatch Only includes an in-depth take a gander at all the key components of the Speedmaster Moonwatch. The electronic version includes the accompanying: Caliber, Caseband, Dial, Bezel, Hands, Caseback, Crown, Pushers, Glass and Bracelet. For each component, you can locate all the different versions that have been produced by Omega, from 1957 to the current line-up of watches, including the recent Speedmaster 60th Anniversary. Of course, as an electronic version of the book, E-Moonwatch Only is somewhat less informative, and it basically focusses on key details and high-res images.

As you can see here, each component has its own dedicated page, with reference numbers or detailed data. Snap on the component itself and you’ll have access to HD images (which are, of course, exclusive to the book). The objective here is clearly to educate, compare, understand – and essentially, to verify the authenticity of every single part that composes an Omega Speedmaster Moonwatch.


As with the components, every single model of the Speedmaster collection, from 1957 to 2017, whether from the standard creation or from limited editions, are explored and dissected. For instance, click on any of the models and you’ll have the reference, yet additionally the approximative range of serial numbers (useful to see if the case and movements are coordinating with the model in question), lastly, the reference of all components that ought to be in the selected model.  If the Speedmaster you’re exploring is a limited edition or one with low creation numbers, you’ll even skill a considerable lot of them have been produced.

Finally, similarly as with components, on the off chance that you click on the watch itself, you’ll access superb and extremely detailed HD images of the watches. Now, you have the apparatuses to become an expert… And as though that were not enough, Grégoire Rossier and Anthony Marquié have even devised an extra clever device for you, to rapidly identify a Speedmaster Moonwatch.

The identification tool

Because E-Moonwatch Only is meant to be a mobile guide to be read for the most part on iPhones and iPads (even in the event that it is additionally available on Mac – all the screenshots here are from a 27″ iMac – and obviously, the larger the screen the more comfortable the reading experience will be), Grégoire Rossier and Anthony Marquié imagined that it would clever to include a traveler’s instrument to help identify Speedmasters in under 5 minutes – and on that we have to agree, it is indeed very clever. The goal is to rapidly define if a watch  is legit, or on the off chance that it is one of these doctored/Franken watches we see way too often.

How does it work? Simple. Take the watch in question with you, check it throughly and start the identification program. Initial step, select the type of dial logo (applied or printed), then the type of carries or the type of indexes (tritium or luminova), then the type of dial or caseback, etc, to at last discover the exact reference you have before you. Of course, this program is evolutive and differs depending on your answers. It may request the type of indexes, the type of bezel, the type of graduation on the bezel, the type of hands… However, in the event that at one point you can’t discover the choices offered by E-Moonwatch Only on the watch you have before you… You should step out of the shop!

Here’s an example of an identification process, step by step (of course, this process will be different depending on your answers and can include much more steps)

This device is extremely simple and useful for all Speedmaster collectors. It won’t ever prevent you from being extremely careful when purchasing a vintage piece, however it must be said, it is a genuinely effective prevention instrument. From now into the foreseeable future, there will presently don’t be an excuse for purchasing a doctored Speedy!


The last device included in E-Moonwatch Only is for the hardcore collectors. All references and models are organized into several tables, with creation dates, serial numbers, references numbers, movements and engravings on the caseback. You said geeky? We say die-hard aficionados… But this is likewise why Moonwatch Only, and its electronic version E-Moonwatch Only, are so fascinating.
