News on the production of the DAY41

In our last email on April 7, we told you that the first series units were about to leave the factory. With the intervention of Covid, receipt of these pieces is now scheduled for the end of June. The contrast of the black dials will be accentuated and the finishing will be perfect. We won’t forget to show you when the moment comes. However, some important progress has been made since April 7, on both the cases and the dials.

Case and dial production stage

The cases

They will hold your Swiss STP skeleton movement for decades, whatever the weather. For that to happen we need to move on to the stamping phase and arm ourselves with the appropriate tools. What’s the aim of this phase? Blocks of steel are cut out and then struck with the die in order to begin shaping the case. 5 to 6 strikes per block of steel (sometimes as many as 20, depending on the complexity of the design) are required to obtain the desired case shape. Between each strike, the steel is heated to soften it and optimize its malleability.

Piercing through CNC machining

The stamping is now complete and the case has taken on its definitive form. It’s now time to pierce the holes for the screws and the crown, as well as the seats for the glass, dial and movement. This process is done through CNC machining.

What is CNC machining?

CNC machining uses computerized numerical controls. The milling machines used are automated and computer-controlled to machine a block of material into a piece.

Case finishing

Next, we perform the various surface treatments: polishing, satin-finishing, and micro-bead blasting. For colored pieces, the PVD treatment is applied at the very end.

The dials

The DAY41 dials are made from brass, and must also undergo CNC machining. In terms of finishing, there are a few important steps to be carried out:

  • “Côtes de Genève” : the most well-known of all watchmaking decorations.You could just call them stripes; however, with immaculate execution and favorable lighting, Geneva Stripes accentuate the mechanical esthetic of a wristwatch.
  • Satin-finishing: this decorative process consists of covering a metallic surface in a multitude of extremely fine parallel stripes. The effect created is clean and regular, its ruggedness catching the light at different angles.
  • Micro-bead blasting involves bombarding the surface of a watch with little metal balls. It gives a mat finish that reduces light; the opposite of the majority of surface treatments, which typically aim to increase shine.
  • Color treatment with plating bath: this decorative effect is achieved through electroplating. It uses a continuous electrical current (on a dial or movement) to deposit a metal coating on the original material; the treated object is simultaneously protected from oxidation.
  • Applying luminova to the hands: this process is so delicate that it is performed by hand with a little syringe. This allows you to read your watch in the middle of the night without squinting your eyes.

As you can see, your DAY41 is in good hands; each step is being carried out strictly by experienced professionals. As soon as we receive the images, we’ll share them with you immediately. Also, in terms of delivery dates, we’re still working with a month of delay due to the health situation. We’ll do everything that we can to reduce this delay, but our number one priority is quality, which is why we’re following the production process very closely, and why we’ll continue to relay all the thrilling news from behind the scenes.

    Hi there

    We have already purchased a watch for my husband but would love to find out if you may have any Day 41 watches in rose gold?

    Best wishes

    Bonjour !

    J’étais impatient d’avoir ma nouvelle montre et maintenant que je l’ai je suis impatient de la montrer !!! Elle est aussi belle que je l’espérais ! J’avais un peu peur que le boitier que j’avais choisit soit trop grand et en fait il est parfait pour mon poignet !!! Juste que je me suis trompé dans la taille du bracelet, j’aurais du prendre la plus grande taille… Sinon expérience géniale !

    Bien à vous et continuez ainsi !

    Vous presentez un chrono sur la photo de l’annonce, mais je n’en trouve pas dans votre catalogue.
    En proposez-vous une ou y en a t-il une en projet ?
