Apple Watch has operating issues on tattooed wrists

It has been learned in these hours that Apple has issued a specific communication addressed to potential buyers of Apple Watch.
The first smartwatch from the Cupertino company would indeed carry a sort of structural “limitation” that is well to keep in mind.
Before controversies break out as in previous cases of bugs or manufacturing defects in Apple products – let’s recall the “Antennagate” incidents as an example – the company has apparently decided to lay all its cards on the table, admitting that Apple Watch does not work optimally in the presence of tattoos on users’ wrists.
The support page for Apple Watch on Apple’s official website has been updated, with an explicit reference to this issue.
It reads: “Permanent or temporary changes to your skin, such as some tattoos, can affect the performance of the heart rate sensor” and further, it explains this limitation: “The ink in some tattoos can block light from the sensor, making it difficult to get reliable readings.”
It seems that the sensors located on the back plate of the smartwatch – therefore those in direct contact with the skin of the wrist – are unable to fully “read” the information related to the heartbeat of the device wearer. This would happen especially with dark-colored tattoo ink. The sensors actually emit red and green infrared light beams, capable of “reading” blood flow on the wrist. With dark marks, this mechanism would not activate at all or would only work partially and intermittently.
In addition to not being able to correctly detect some fundamental information for the proper functioning of health or fitness apps for the user, Apple Watch would not even be able to correctly recognize the contextual use of the smart watch itself.

The same sensors, in fact, also serve to communicate to the device whether the smartwatch is actually on the wrist at that moment or is still, for example, placed on the nightstand or desk in standby mode.
Therefore, if you are considering purchasing an Apple Watch but have a tattoo on your wrist, it would be well to consider all the limitations of the case, as Apple itself suggests.
It is not yet possible to know if this aspect will be resolved in some way or if, on the contrary, the Apple Watch will remain exactly the same as this first batch released on the market.
