Does the Apple Watch Work on Tattooed People?

Is this an isolated incident or does the Apple Watch not work on people with tattoos covering their wrists?

“Reddit user Guine55fan purchased the 42mm SS watch and found himself unable to get any notifications when he placed it on his wrist. In fact, the watch locked up and asked for his password once it would go dark. Guine55fan has a tattooed sleeve that covers his left arm, including the spot on his wrist where the watch rests. Curious to find out why the watch wasn’t working Gunie55fan slid the watch down to an untattooed part of his hand and lo and behold the watch worked beautifully.”
