Fitness tracker HR monitor that doesnt look like a machine on my puny wrists?

[Chicinwellies]

Im looking for a fitness tracker with built in GPS and Heart Rate monitor (no seperate straps or taking phone with me). The Fitbit surge looks fab but Huge, and I have really, small wrists! Anything vaguely 'stylish' out there so I feel happy wearing it all day / work etc? Thanks

The second gen Apple Watch has GPS.

I second the Mi Band. It's really slender and really good value for money. The delivery is a pain as it's from China but well worth it.
