The Core Time 2 mentions heart-rate monitoring. Have you considered also adding an oximeter?

The comparison chart, under "sensors", doesn't mention the compass under the Core Time 2; does the Core Time 2 drop the compass? A 3D magnetometer seems like a useful sensor for orientation purposes.

Is there a light sensor, to allow automatically disabling the backlight when there's enough ambient light and enabling it when there isn't?

You mention "Standard Pebble charger" for both; I'm guessing that that isn't USB-C?

You cannot put oximetry in a watch without getting sued by Masimo. Just ask Apple.

The heart rate sensor patents were ruled unpatentable:

> This week, the US Court of Appeals for the Federal Circuit upheld the previous verdict of the Patent Trial and Appeal Board that concluded all three of AliveCor’s patents were unpatentable. This is generally the outcome when courts conclude that patents are either obvious or too generic to enforce.

The case over the oximeter functionality is still ongoing, but with luck it'll go the same way.

It looked like it was not just the oximeter but the arrangement of the sensors and the fact that they fist approached Masimo with a licensing deal but then canceled and hired engineers from Masimo instead....

That story is about heart rate sensors. The Masimo case is about oximetry, and AFAIK Apple is still blocked from selling watches with this feature.

I think the article is referencing two different cases, and the ones invalidated don't seem related to oximetry, I'm not sure what happened with the oximetry one though.

The 360° view on the product page shows the charger interface on the back of the watches. Definitely not USB-C!

Ah, when it said "standard Pebble charger" I incorrectly assumed it was a charging port, rather than something like pogo pins. What's on the back of the watch seems pretty reasonable.
