Best place to buy a smart watch/fitness watch/activity tracker in Bangkok?

[ExistentialInquiry]

Hi

 

I've got a Garmin Forerunner 935 which I'm very happy with, but I've been looking to buy a cheaper and more basic alternative as a present for a friend. Garmin's are very expensive here in Thailand, but looking on Lazada I see they've got tons of smartwatches from various Chinese and other brands with optical HR monitoring, bluetooth pairing, workout uploading etc.

 

The question is, where would be the best place to physically buy one in Bangkok? I guess I could buy online but I've only just moved here so would rather go and get one in person, and have a chance to look at them first, too. I had a look around Silom Complex in Sala Deung but no luck there. Any recommendations? There must be an electronics hotspot in Bangkok somewhere.

 

Thanks
