According to market analysts, the new Lumia 800 and the Lumia 710 represent the Finnish firm's fightback against Apple's iPhone.
Nokia's new boss, Stephen Elop, commented: "Lumia is the first real Windows phone."
Furthermore, he also suggested that the company would eventually become the leader in "smartphone design and craftsmanship".
"We expect people to see something special when they hear Nokia," he added.
Nokia faces stiff competition in the wireless communications device market, especially as Apple only recently launched its iPhone 4S handset.
The handset, the first launched since the death of Apple co-founder Steve Jobs, has been confirmed as its best-selling device by pre-order sales.
Consequently, some analysts are sceptical as to whether Nokia will be able to compete.
