How to Engrave Watches with a Fiber Laser

Customized watch engraving elevates timepieces from functional accessories to meaningful treasures. Whether commemorating a milestone or branding a batch, fiber lasers bring precision, speed, and durability when engraving steel or metal watch backs. In this guide, we’ll walk through the process—from material selection to finished design—and highlight why OMTech fiber laser engravers are the go-to choice for watch customization.

What Makes Fiber Lasers Ideal for Watches

Fiber lasers offer clear advantages over traditional engraving tools or CO₂ lasers:

• High precision, non-contact technique: Crucial for preserving delicate watch mechanisms and finishes. Fiber lasers remove material through highly focused light—no physical contact needed.
  

• Metal versatility: Ideal for stainless steel, titanium, aluminum, and even gold alloys. The laser etches directly into the metal, creating long-lasting, sharp marks.
  

• Fast and consistent: What takes minutes by hand can be done in seconds—perfect for either bespoke or batch engraving. 

What Metals Can You Engrave?

Common watch back materials work exceptionally well with fiber lasers:

• Stainless Steel: Durable and reflective—ideal for clear engraving contrast.
  

• Titanium: Light, hypoallergenic, and amenable to detailed marking.
  

• Aluminum: Soft, great for quick engraving; anodized versions yield beautiful contrasts.
  

• Gold & Brass: Fiber lasers can etch into luxury materials—clear, elegant, and ready for personalization.

Note: Avoid engraving sapphire (glass) casebacks unless using a specialized UV laser—these require different techniques and may obscure visibility.

Step-by-Step: Engraving a Watch Back via Fiber Laser

1. Prepare Your Watch Back

• Remove the watch strap or case to provide a flat, stable engraving surface.
  

• Clean with isopropyl alcohol to remove oils or debris.

• Measure the diameter of the watch back to plug into LightBurn later. 

2. Set Up the Rotary or Flat Bed

• For cylindrical elements like crowns, fit the watch into a rotary chuck to enable smooth rotation during engraving.
  

• For flat watch backs, place them securely on the flat area of the laser bed using non-reflective clamps or magnets.

3. Focus the Laser

• Use an autofocus feature (if available) or manually focus by lowering the head until you see the red guide point sharpen. Proper focus ensures fine detail and minimizes overburn.

4. Upload Your Design

• Use vector-based designs with clear outlines—names, dates, logos, or serial numbers work well.
  

• Adjust design size to fit the watch back’s diameter using LightBurn or similar software.

5. Run a Test on Scrap Metal

• Before engraving the actual watch, test on metal scraps—this helps fine-tune settings without risking the watch.

6. Engage the Laser Engrave

• For steel, we used 80% power, speed at 1000, and a frequency of 80. Adjust based on preview or visual feedback.

7. Inspect & Clean Post-Engraving

• Wipe the engraved area with soft cloth and isopropyl alcohol. Check for clarity and placement accuracy.

8. Reassemble Watch

• Once satisfied, re-install the case back and any removed parts, ready to wear or package.

Best Practices & Tips

• Rotate the font or image slightly to match the curvature of the watch back if using rotary setups.
  

• Apply masking tape on high-polish surfaces to protect from stray burns and ensure cleaner lines.
  

• Use moderate power to avoid over-etching. Always test first!
  

• Consider font choice carefully—a classic, clean typeface remains timeless and legible.
