My creations respect the purity of the forms and the balance of the lines. What makes these creations of an unequalled beauty.

My creations are all made with finesse and precision for more elegance and robustness thanks to my know-how.

The term MOD is the ability to modify a watch. Seiko is a Japanese brand, very popular with fans of customization. Almost all parts and other mechanisms of the watch are available for purchase from Seiko or Namoki for example (hands, bezel, crown...)

What has made the strength of Seiko and increases the popularity of mods is the fact that they offer a great customization of their watches, while facilitating the process of creation, thanks to its wide choice of available parts. Thus, we can take watches like the Seiko Prospex Diver, SKX, Seiko 5 Sports or even SNXJ89 as well as the new Seiko 5 GMT SSK001, SSK003, SSK005 and modify them according to your tastes, your passion and your desires of the moment.

This activity is a passion.
I am very knowledgeable about parts compatibility. Watchmakers and jewelers (most anyway) probably don't spend the time I spend looking at hundreds and hundreds of mods to learn about possible modifications and combinations.
I am very reactive to give you the answers to your questions.
I bring a maximum of advice thanks to my experience.
In addition, I offer the water resistance test as well as the adjustment of the movement with timegrapher for each watch.

Here is a list of parts suppliers I enjoy working with:

I also have a lot of personal contacts and suppliers who may have certain parts.

The full custom watches I make come with a 3-year warranty, but I'm not responsible for any damage that may occur to the watch. I simply have no way of knowing whether the wearer of the watch made sure that the crown was screwed in before swimming with it, that he didn't change the date or the day during the death zone (see instructions)... I'll fix what I did by mistake, but it's highly unlikely.

For more information, see Article 8 of the T&Cs.

About

My name is Billy, I live in the Toulouse region in France, I assemble and modify watches watches since 2017.

I started by making small changes to my watches, people soon became interested in what I had on my wrist and asked me to make watches for them.

I then decided to throw myself fully into this passion by always offering more possible watches configurations.
