How our watches are made.

Precision and care at every stage, from the movement to the dial: eight steps to bring Theorema to your wrist.

Fixing the movement

01

Fixing the movement

The movement is fixed onto the movement holder: stability and correct alignment for every later stage.

  • Gentle placement on a support that gives a stable base.
  • Centring and alignment, to avoid imbalance or malfunction.
  • Stability check: no play and no sideways movement.
Placing the dial

02

Placing the dial

The dial is the most visible part of the watch and is fitted with great precision for clear reading.

  • Dial inspection: no dust, scratches or imperfections.
  • The pins on the back go into the movement’s fixing holes.
  • Final check: perfectly centred and stable.
Fitting the hands

03

Fitting the hands

Hours, minutes and seconds are fitted with absolute accuracy so that the mechanism works and reading is clear.

  • Hands inspected: no scratches or deformation.
  • Hours first, then minutes, finally seconds: the thinnest and most fragile hand.
  • Free-rotation check by changing the time, with no collisions.
Fitting into the case

04

Fitting into the case

The case protects the movement from the elements and keeps it stable.

  • Case cleaned inside and out, gaskets checked.
  • Movement centred and aligned with the crown hole.
  • Locked with an adapter: fewer vibrations, correct operation.
Fitting the crown

05

Fitting the crown

The crown winds the watch and sets the time: its installation is essential for function and protection.

  • Stem length carefully calculated for a perfectly flush crown.
  • The stem connects to a gear in the movement.
  • Gasket for water resistance, plus winding and setting tests.
Closing the caseback

06

Closing the exhibition caseback

The caseback seals the movement; the glass at its centre lets you admire it at work.

  • Caseback carefully cleaned, especially the transparent part.
  • Gasket centred to protect from water, dust and humidity.
  • Screw closure without excessive pressure, then a visual inspection of the movement.
Water-resistance test

07

Water-resistance test

A pressure chamber checks that the watch is waterproof and resists dust and humidity.

  • Complete watch with the crown closed, as in real use.
  • Pressure applied gradually, with sensors looking for leaks.
  • If the test is passed, gaskets, caseback, crown and glass are correctly fitted.
Fitting the bracelet

08

Fitting the bracelet

The stainless steel bracelet completes the look and ensures comfort and security.

  • Links and spring bars checked: clean and flawless.
  • Precise alignment of the bracelet to the case.
  • Spring bars compressed with a dedicated tool and inserted into the case holes, where they expand.
