Choosing the Right Movement

Selecting the appropriate movement is a critical step in building a watch, as it determines the watch’s functionality, accuracy, and overall complexity. Movements generally fall into three categories: mechanical (manual), automatic, and quartz.

Mechanical movements rely on a mainspring that must be wound periodically. They are prized for their craftsmanship and traditional appeal but require more skill to assemble and maintain. Automatic movements are a subtype of mechanical that wind themselves using the motion of the wearer’s wrist, offering convenience without sacrificing the mechanical charm. Quartz movements use a battery and a quartz crystal to keep time with high accuracy and less maintenance, making them an excellent choice for beginners or those prioritizing precision.

When choosing a movement, consider these factors:

  • Skill Level: Mechanical movements require fine assembly skills; quartz movements are simpler.
  • Budget: Mechanical and automatic movements are generally more expensive.
  • Functionality: Additional complications (chronographs, date, power reserve indicators) impact movement choice.
  • Aesthetic Preference: Some prefer the traditional sweep of mechanical second hands over the tick of quartz.
Movement Type Power Source Maintenance Accuracy Assembly Complexity
Mechanical (Manual) Wound mainspring Regular servicing required Moderate (±5 to 10 seconds/day) High
Automatic Wound by wrist motion Regular servicing required Moderate (±5 to 10 seconds/day) High
Quartz Battery Battery replacement every 1-3 years High (±10 seconds/month) Low

Assembling the Watch Movement

The assembly of the watch movement is a meticulous process requiring precision tools and a controlled environment to avoid dust and contaminants. Begin by carefully unpacking the movement and inspecting all components for damage or defects. Use a loupe or microscope to examine tiny parts such as gears, screws, and jewels.

Follow these essential steps during assembly:

  • Lubrication: Apply specialized watch oils sparingly to reduce friction and wear. Over-oiling can attract dust or cause movement malfunctions.
  • Gear Train Installation: Place the gear train carefully, ensuring that wheels mesh correctly. Misalignment leads to inaccurate timekeeping.
  • Balance Wheel and Escapement Setup: This is the heart of the movement. Handle with extreme care to avoid bending or damaging the delicate parts.
  • Testing Functionality: Once assembled, check the movement’s operation by manually winding and observing the gear train and balance wheel activity.

Using the correct tools is essential. Some of the common tools include:

  • Tweezers (preferably anti-magnetic)
  • Screwdrivers sized for watch screws
  • Movement holder to secure the movement
  • Oiler pens for lubrication
  • Rodico putty for cleaning

Dial and Hands Installation

Once the movement assembly is complete and tested, the next step is to install the dial and hands. This stage requires precision to ensure proper alignment and clearance.

Start by attaching the dial feet to the movement. Most dials have protruding feet that fit into corresponding holes on the movement plate. Secure the dial with screws or clips depending on the movement design.

When fitting the hands, use a hand presser tool to avoid bending or scratching them. Install the hands in the following order:

  • Hour hand: Align it precisely at the 12 o’clock position.
  • Minute hand: Also set at 12 o’clock but above the hour hand.
  • Second hand: If applicable, install as the topmost hand.

Ensure there is adequate clearance between the hands and the dial as well as between the hands themselves to prevent interference during movement.

Case Selection and Assembly

Choosing the watch case involves balancing aesthetics, material properties, and compatibility with the movement and dial. Common case materials include stainless steel, titanium, ceramic, and precious metals. Each material offers different benefits in terms of durability, weight, and corrosion resistance.

When selecting a case, consider:

  • Movement Size Compatibility: The movement must fit securely inside the case.
  • Water Resistance Features: Look for cases with screw-down crowns and gasket seals if water resistance is desired.
  • Crystal Type: Sapphire crystals are scratch-resistant and preferred for higher-end watches, while mineral glass is more budget-friendly.

To assemble the case:

  • Place the movement and dial assembly carefully into the case body.
  • Secure the movement with case clamps or screws.
  • Attach the crown stem by inserting it through the case tube and into the movement, ensuring proper engagement.
  • Install the crystal if it is not pre-fitted.
  • Seal the case back tightly, often with a gasket, to maintain water resistance.

Final Adjustments and Testing

After assembling the watch fully, perform final adjustments and testing to ensure reliable operation and timekeeping accuracy.

Adjust the regulation of the movement using the regulator arm or screws to fine-tune the rate. This process may require timing equipment like a timegrapher to measure the beat rate and amplitude.

Test the watch under various conditions:

  • Position Testing: Check accuracy in different orientations (dial up, dial down, crown up, etc.).
  • Power Reserve: Verify the movement runs for the expected duration after winding.
  • Water Resistance: If applicable, test seals and gaskets for leaks using pressure testing devices.
  • Wear Simulation: Observe movement stability and hand clearance
