Unlike the Style, on the Sport the antenna extends into the strap, which means it only fits proprietary, non-changeable, bands. These are rigidly angled inwards, but while I found this a little annoying on the Asus ZenWatch 3, I see its merits for heart rate tracking on the Sport and generally making the watch feel snug on the wrist while exercising.
Casio has just announced their second smartwatch, and it's pretty cool. The Casio Pro Trek Smart WSD-F20 GPS watch review builds on last year's WSD-F10 with an updated look but, more importantly, new and compelling functionality.
The Astron is a tremendously important and innovative watch for Seiko – it takes its name from the first quartz wristwatch, developed by the brand in 1969. The orginal Astron was a major milestone, not just in watchmaking, but in the history of electrical engineering.
