Who am I? //


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.

Great service, fast communication and delivery!
I got the watch in Sweden 1 day after it was sent from France. This is without a doubt the best service and communication I have ever experienced from a company abroad. I will order again 100%. Thank you so much, the watch is awesome.

Billy helped me build my dream watch and the final result is better than I could hope for. Easy communication through the whole prosess and he was able to do changes to the watch when I changed my mind. Highly recommend his services and I'll order more watches from him in the future for sure.

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.

I make full custom Seiko watches to order, a form is available to make your request. 

I also work with a company that can engrave the Caseback and the crown.
