Withings ScanWatch Horizon

Interesting product. I appreciate some of the practical touches of a diver's watch:

1. It has all the health monitoring things (heart rate, ECG, oximeter, sleep).

2. It has 30 day battery life.

3. It has a sapphire glass (scratch resistant).

4. It has 10 ATM water resistance (100 meters/330 feet).

On the other hand, the screen part of this watch seems very small, it doesn't run a standard smartwatch OS, and the water resistance isn't an outright claim of being waterproof (so likely OK for swimming but not scuba diving). An alternative like the Garmin Fenix (https://www.garmin.com/en-US/p/641479/pn/010-02158-13) seems more practical in terms of screen size, although it is pricier and doesn't have the oximeter.

Looks great and I love my basic ScanWatch. But I find it frustrating that there's so many unexplored opportunities on the software side that Withings seems to ignore. I'd love an SDK for their watches, or just a very basic API to display some custom data on the watch from my phone. (One use-case would be to create a weather widget there.)

They advertise: “ScanWatch Horizon seamlessly tracks all your activities... Smart detection and connected GPS give you precise insights.”

Click through for more and they say: “Map your workout sessions and enjoy distance, elevation, and path with Connected GPS.“

Which all seems to be marketing speak for “doesn’t actually have GPS, but you can bring your phone instead”

That’s verging in deceptive, I think! I only worked it out because I was interested in how the stated battery life was achieved with a GPS in there and so started googling.
