Masimo, the company that sued Apple over patent infringement, has unveiled its own blood oxygen monitoring smartwatch called the Masimo Freedom.
The Masimo Freedom is a health-focused device that can track blood oxygen levels, hydration index, respiration rate, pulse rate variability, pulse rate, steps, and detect falls.
The smartwatch is currently in prototype stage and will be available for sale later this year at a price of $999.

Probably not, most of those sensors work by shining an LED light through the skin and monitoring reflection/scatter as a cheap form of photoplethysmography. Anything capable of absorbing that light, like the pigment used in tattoos, will prevent it from working correctly (at least out of the box, there may be some way to adjust for it but I do not think it would be very accurate).

An infrared sensor could work, depending on the ink type. Unfortunately those are more expensive.
