Logbook of production, chapter 3: the watch straps

green leather watch strap union collection

The watches from the Union Collection are about to be assembled in our Parisian Atelier. Since moving from pocket to wrist, watches now require straps.

Our Union Collection offers three leather bracelets in blue, black, or green, whose exotic details give real personality to the watches. What makes it distinct? Each bracelet is handmade and artisanal, making it truly unique.

The manufacture of our bracelets has begun. The leathers are bought raw, then prepared, and tanned in the atelier. How does it work? The leathers will undergo different treatments, carried out by specific (and traditional) machines. These machines are essential for refining and tanning the skin.

Of course, as with every element of the watch, if certain pieces of leather do not have the quality necessary for the manufacture of our bracelets, they must be permanently removed from the production chain. The team is, therefore, busy detecting scratches and stains on the skins to keep only the best quality parts.

After having selected the pieces that we will use to make the bracelets, we must dye the skins to obtain the colors of our bracelets: green, blue, and green. It will then be a question of completing the details in alligator, for the black and blue bracelet, and the téju for the green bracelet.

When we have the desired results, the skins are polished to obtain the best possible finish to protect the leather in the long term.

Once the leathers are stored, we begin cutting the skins in the best parts to obtain the different elements that will constitute the bracelet.

A bracelet is composed of a skin carefully selected on the top added with a leather lining imperatively treated to be biocompatible (hypoallergenic among others). Between these two strips of leather, we place a tear-resistant reinforcement to make the bracelet, not only more comfortable but also more durable over time in the face of daily use. These three elements are glued together and then sewn by hand. 

To achieve tone-on-tone solid topstitching, our leather craftsmen use the saddle stitch. Saddle stitching is done with only a few feet of thread at a time and must be made by hand. To create each stitch, the entire thread serpentines two times through the layers of leather.

The final touch is the application of a colored resin to protect the edge of the leather. For the blue and green bracelets, we chose an azure resin, for an even more pronounced contrast.

Now we will cut the bracelet to be able to insert the flash pump. It will allow you to change your bracelet with more ease at home, without tools. Of course, this bracelet manufacturing process ends with quality control before receiving them at the atelier. There they will then be added to the watches, depending on the choices you have made.
