mtk6739 bluetooth version

Hello,

I saw in a few places where smartwatches are advertised as having an mtk6739 and Bluetooth 4.0.

But when I check the MediaTek website (https://www.mediatek.com/products/smartphones/mt6739) for specs about the mtk6739, I see that they advertise it as having 4.2 (Low Energy).

I want a smartwatch with at least Bluetooth 4.2 on it. So, can someone confirm for me whether the mtk6739 has a Bluetooth 4.0 on it or a Bluetooth 4.2 as advertised on the Mediatek website?

Cheers,

GL
