Nice, as someone who has done some product research for specialized smartwatches, these specs are pretty much the go-to standard for generic chinese mid-range smartwatches.

Definitely a great base for an open source smart watch. You can do a lot with that!

‘Dimensions: 43 mm diameter, 16 mm thick’

How much is 16mm compared to other similar watches ?

Nice but it feels like a rather thick stack for a watch.
