[QA] 2X set of tests

Guys,

Calling all with QA (quality assurance) experience and simply all you reasonable people.

I'm planning to purchase an Instinct 2X Solar as a gift.

Meaning, buying it now and gifting at the next big holiday.

Is there any way to run some kind of 

- self-checks/tests on the watch and/or

- a set of manual checks

to make sure the watch is functionally fine?
What functions would I need to test?

I would like to make sure all the core sensors are fine and all the basic functions are okay.

Thanks in advance.
