Selecting and Preparing the Movement

The heart of any watch is its movement, which powers the hands and complications. Choosing the appropriate movement depends on the type of watch you intend to build—mechanical, automatic, or quartz. Mechanical and automatic movements are preferred by enthusiasts for their craftsmanship, while quartz movements offer precision with minimal maintenance.

When selecting a movement, consider the following factors:

  • Size and dimensions: Ensure the movement fits the case and dial.
  • Functions: Determine if you want a simple three-hand movement or additional complications like date, chronograph, or moon phase.
  • Power source: Manual winding versus automatic self-winding or battery-powered quartz.
  • Quality and origin: Swiss, Japanese, or other manufacturers with varying price points and reliability.

Once chosen, the movement must be handled with care. Before installation, confirm it is fully functional and calibrated. Use anti-static gloves or finger cots to avoid contamination or damage. If assembling a mechanical movement from parts, clean all components thoroughly, then lubricate moving parts with the appropriate watch oils according to manufacturer specifications.

Constructing the Watch Case

The case not only houses the movement but also protects it from dust, moisture, and shocks. Case construction requires precision machining or purchasing a ready-made case compatible with your movement.

Key considerations during case construction include:

  • Material: Stainless steel, titanium, brass, or precious metals each offer unique aesthetic and durability characteristics.
  • Dimensions: Diameter, thickness, and lug width must align with the movement and strap.
  • Crystal: Choose between sapphire, mineral glass, or acrylic depending on scratch resistance and cost.
  • Case back: Options include solid, exhibition (transparent), or screw-down for water resistance.
  • Water resistance: Seal integrity is crucial; use gaskets and ensure correct assembly to achieve desired ratings.

If fabricating a case yourself, CNC machining or precision casting techniques are typically employed. After machining, surfaces are polished or brushed to the desired finish. Threaded components such as the crown tube and case back require precise threading to ensure water tightness.

Dial and Hands Installation

The dial is the visual centerpiece, so aligning it perfectly within the case is essential. The dial must have appropriate feet to secure it onto the movement, ensuring stability without affecting movement operation.

When installing hands:

  • Use specialized hand-setting tools to avoid damaging the dial or bending the hands.
  • Press hands gently onto the pinions, starting with the hour hand, then the minute, and finally the second hand if applicable.
  • Check hand clearance to prevent interference during rotation; there should be minimal vertical and horizontal play.
  • Verify proper alignment at the 12 o’clock position for accurate time reading.

Assembly and Final Testing

After assembling the movement inside the case and installing the dial and hands, the watch requires final assembly:

  • Attach the crown and stem, ensuring smooth winding and time-setting functions.
  • Secure the case back with the appropriate gasket for sealing.
  • Mount the strap or bracelet, checking for comfort and secure attachment.

Final testing includes:

  • Timekeeping accuracy: Use a timing machine to adjust the movement within manufacturer tolerances.
  • Water resistance: Conduct pressure tests if applicable.
  • Functional tests: Verify all complications operate correctly, such as date changes or chronograph resets.
  • Wearability: Evaluate comfort and ergonomics on the wrist.
