How Watch Parts Are Made
Each watch component is a product of specialized manufacturing processes designed for precision, durability, and aesthetic appeal.
1. Case Manufacturing
- Materials: Stainless steel, titanium, gold, ceramic, and more.
- Process:
- Cases often begin as solid blocks which are stamped or CNC-machined to form.
- They are then painstakingly polished, brushed, or textured.
- Details: Water-resistant cases require intricate drilling and threading for crowns/screw-down backs.
2. Crystals
- Types: Sapphire (most scratch-resistant), mineral glass, or acrylic.
- Manufacture: Crystals are cut, formed, and polished to fit the case shape and required thickness.
- Coatings: Often treated with anti-reflective coatings.
3. Dials and Hands
- Dial: Made from brass or other metals, then painted or coated and printed with indices.
- Markers: Applied by hand or machine. Some have lume (glow-in-the-dark paint) for visibility.
- Hands: Precision-cut, sometimes heat-blued or polished for effect.
4. Movements
- Mechanical/Automatic: Hundreds of micro-components—gears, jewels, springs—mostly made with CNC machines and assembled by skilled technicians or robots.
- Quartz: Fewer moving parts; relies on an electronic circuit and battery.
5. Gaskets and Seals
- Manufactured from rubber, silicone, or advanced synthetics for flexibility and longevity.
6. Straps and Bracelets
- Multiple materials and methods: stitched leather, cast and finished metals, or molded rubber.
Sourcing Watchmaking Parts
Whether repairing, modding, or building your own watch, knowing where to find reliable parts is crucial. Many suppliers and specialty shops cater to different levels of expertise.

Searching for kits that include both tools and replacement parts can be an excellent entry point for beginners.
Step-by-Step: Assembling a Watch with Parts
Let’s walk through a simplified overview of building a complete mechanical watch from parts.
1. Prepare Your Workspace
- Ensure a clean, dust-free, and well-lit area.
- Lay out tools and parts on a soft mat to prevent loss or scratches.
2. Inspect All Parts
- Check all components for damage, especially the crystal, hands, and movement.
- Organize screws and small parts to avoid confusion.
3. Install the Movement
- Place the movement in a holder.
- Attach the stem to connect the movement to the crown.
4. Attach the Dial
- Gently seat the dial onto the movement’s posts.
- Secure it with the provided screws.
5. Install the Hands
- Use hand-setting tools to mount the hour, minute, and second hands carefully.
- Align for perfect time indication and clearance.
6. Case Assembly
- Insert the assembled movement, dial, and hands into the watch case.
- Fit the crown and stem through the case.
- Double-check gaskets are correctly seated for water resistance.
7. Secure the Caseback
- Align and screw or press the caseback securely.
- Inspect the assembly for gaps or misalignment.
8. Attach the Crystal and Bezel
- Use a press to fit the crystal (if not pre-installed).
- Affix the bezel, ensuring it is properly snapped or screwed into place.
9. Install the Strap or Bracelet
- Fit strap/bracelet to the lugs using spring bars and the appropriate tool.
10. Test the Watch
- Wind the movement, set the time, and observe operation.
- Check for smooth hand movement and correct case sealing.
