Whether you’re a hobbyist modder or a professional watch shop, choosing the right laser engraver can make or break your business.
If you mainly engrave brass, stainless steel or titanium watch dials, choose a fiber laser.
If you engrave sapphire watch crystals or need ultra-fine logos, choose a UV laser.
If you engrave leather straps or packaging, choose a CO2 laser.
Here’s why.
What Parts of a Watch Can Be Laser Engraved?
Laser engraving is used throughout the watch industry, from dials and case backs to crystals and straps.
Laser technology enables precise and durable finishing of semi-finished products such as case centers, bezels, and backs.
Different laser technologies excel at different applications. Choosing the wrong one means wasted money and disappointing results.

Case Study: Crafting a Jurassic Theme Deep‑Engraved Brass Dial with ComMarker Titan
1.Design & Preparation – Create a greyscale pattern of gears and mechanical structures in LightBurn or EZCAD.
2.Parameter Setup:
Brass engraving: ComMarker Titan 60W MOPA fiber laser
Lens: 110mm; Speed: 2000 mm/s; Power: 95%; Frequency: 100 kHz; Pulse Width: 200 ns; Line Interval: 0.025 mm; Layers: 256; Mode: 3D Slice
3.Deep Engraving – Start the job; the laser progressively removes brass material, building up a relief depth of 1 mm or more.

4.Post‑Processing – Lightly polish the engraved dial to remove burrs and apply an anti‑tarnish coating.
5.Result – A brass dial with profound depth and a vintage industrial aesthetic – a result impossible to achieve with standard engravers.
