The global smartwatch market grew to 5.3 million units during the second quarter of 2015 marking a 457% increase in shipments from 1 million units during the same period last year.

Apple was quick to gain the lead and dominated the smartwatch market with a 75% share during Q2 2015. Sales of the Apple Watch clocked in at 4 million units.

According to Strategy Analytics, smartwatch sales in Q2 2015 were higher than the whole of last year, with 4.6 million devices being shipped through 2014.

Appleā€™s chief rival Samsung, despite having multiple smartwatch models on the market managed to ship just 0.4 million units during Q2 2015, capturing a market share of just 8%.

While Apple did not release sales or revenue figures it earned from the Apple Watch during its most recent earnings call, analysts peg revenues at around $1 billion.

The company did say that the Apple Watch beat iPhone and iPad sales in the initial 9 weeks of going on sale, proving that it was a success, but not really putting a number on it.
