Apple Watch pre-orders are off to a solid start - the company received one million pre-orders in the US during the first day of sales - this easily surpassed the 720,000 Android Wear devices that were sold throughout all of 2014 - but it's nowhere near the four million orders received for the two iPhone 6 models during their first 24 hours of pre-sales.

Slice Intelligence, a company who tracks online consumer behaviour has been analysing Apple Watch sales during the first 24 hours - here's what they've come up with:

• The black sport band has proved to be the most popular colour - making up almost half of all pre-sales on the opening day.

• Nearly two-thirds of the orders were for the aluminum sport watch - it starts at $349 (this model is expected to cost €320 in Ireland).

• The top-end $10,000 watch didn't get enough sales to register in Slice's report.

• One third of buyers opted for the $549 stainless-steel watch.

• Apple's trademark 'space grey' has been the most purchased casing option.

• The company also started selling its new Mac Book on the same day - 43 percent of the people who bought the laptop also splashed out on an Apple Watch.

• 71 percent of pre-purchasers bought the larger 42mm watch over the smaller 38mm version.

• Slice found that 72 percent of these early-adopters had bought another Apple product during the last two years.

The first Apple watch reviews came out last week - Newstalk compiled some leading publications' first thoughts on the new product - the reaction was mixed but generally positive.

The overriding question left unanswered was - will the average person be impressed enough with Apple's wearable to buy a first generation watch?

The Apple watch will go on sale in nine countries on April 24th - but Ireland is not on that list.
