Apple has just launched Apple Watch recently and it turns out that it could be the most profitable product from the company. According to Carl Howe from Thing Big Analytics, the company has already sold about 3 million units till to date. It is estimated about 1.8 million Sport models and about 40,000 Edition models have been sold to the public.

Howe posted on his blog that his belief was that the Apple Watch product line would become Apple’s most profitable product line ever, with gross margins exceeding 60 percents. He added that it was because the core electronics modules in the expensive models are the same ones used in the Sport models and they just don’t cost that much.

Apple Watch comes with three different models offered to the public, Apple Watch Sport, Apple Watch as well as Apple Watch Edition. Different models will fit the requirement for different people. Apple Watch for example, it is more to something that is used every day. Apple Watch Sport is suited for people who always on the road as it is more resistant to scratches and impacts while Apple Watch Edition is for fashionista out there since this model has a really great design as it comes with 18-carat gold and the display is protected by polished sapphire crystal.

In January, Apple’s earning is reported to reach $3.06 per share with revenue of $74.6 billion. On April 27, Apple will report the company’s earnings for the first quarter of 2015.
