Following the video-based teaser campaign that saw the handset used and abused, Nokia as now made the 3720 classic, its most rugged mobile handset to date, official.

An IP-54 certified mobile, the 3710 classic is designed to resist water, dust and shock.

Made from durable materials and entirely leak-proof, sealed to protect the inner electronics, the battery cover is locked with a screw for protection in wet, dusty or muddy environments.

"Whether using it at the beach or in a dusty construction site, the Nokia 3720 classic has been specifically engineered to withstand the splashes, bumps and drops that come with the terrain", said Markku Suomi, vice president, connect devices.

"While the Nokia 3720 classic is tough on the outside, it is equally functional on the inside - a perfect choice for people who want a long-lasting and reliable mobile phone for any environment".

As with many other rugged handsets, the 3720 boasts a torch. The only other confirmed specs are a 2-megapixel camera, Nokia Maps pre-loaded on a 1GB microSD card, and a "bright" 2.2-inch display.

We will bring you more info when the Nokia 3720 classic goes on sale this summer, with pre-tax pricing set at 125 euros.
