Wrist watch

Laser marking and engraving a wrist watch using a Speedy flexx

In this tutorial you can learn how to laser engrave and mark materials in a single work process.

Preparation

Materials required:

Wristwatch with a stainless steel case
Lego to use as a jig for positioning the watch in the laser machine

Laser machine used:

Speedy 360 flexx, 80 Watt CO₂
30 W fiber laser
2.85" lens
Vacuum table

Any laser machine from the flexx series can be used to engrave and mark this sample.

Step by Step

Step 1: Design

Start by importing our design template or create your own design. If you use our design adapt it to the shape of the watch. Measure the height difference between the materials. This figure is required for the z-offset (for the watch we used there is no height difference between metal and leather). This step is important. For more tips and help about flexx laser machine technology, visit our flexx page.

Send the job to the laser machine using the following printer driver settings:

Process mode	Resolution	Cut line	Halftone	Others
Standard	1000 dpi	none	Colour	-

Tip:

It is easier to position/adjust the design if the graphic elements for the housing and wristband are sent separately. This allows you to position the graphics precisely with the help of the laser pointer.

Step 2: Laser engraving and marking

Create the parameter settings. Parameters will differ depending on the laser machine used and its available laser power.

Important: When laser engraving a flexx job, always focus on the metal/ the material that will be engraved with the fiber laser source.

Laser Marking (Annealing) Parameters for the watch :

Colour	Process	Power (%)	Speed (%)	ppi/Hz
Black	Engraving FLP	85	3	30000

Passes	Air Assist	Z-Offset	Advanced
1	on	+2 mm	-

Laser Engraving Parameters for the strap:

Colour	Process	Power (%)	Speed (%)	ppi/Hz
Red	Engraving CO₂	15	15	1000

Passes	Air Assist	Z-Offset	Advanced
1	on	-	-

Step 3: Post-processing

Thanks to the annealing process the material surface remains unchanged negating the need for post-processing, while also makinf the watch comfortable to wear.
