Based on the info showing on the Play Store, deliveries are to leave Google’s warehouse (probably in Hong Kong if previous deliveries are a reliable guide) by Monday 7 July. Ordering today, therefore, could see you with a Gear Live in your hands by Tuesday or Wednesday next week.
The difference between the Gear Live and LG’s G Watch is mainly to do with Samsung including a heart rate monitor, although the Gear Live does have a slightly smaller battery at 300 mAh compared to LG’s 400 mAh battery. Regardless of this difference, Samsung claims a full day’s battery life as well.
