Samsung has unveiled a smartwatch with a colour screen that can show alerts, be used for voice calls and run apps.
The Galaxy Gear had been highly anticipated since the firm is currently the world's best-selling smartphone maker and has beaten Microsoft, Apple and Google to unveil such a device.
Samsung called it a "fashion icon".
However, analysts warned that a decision to limit the watch to working as an accessory to other Galaxy Android devices might limit its appeal.
Samsung has previously said growth in the sales of its handsets was slowing, so investors are eager to see if it can find another successful product.
I guess it was an inevitable development for them, but I can't say that any of the 'smartwatches' out there have made me think that I need one yet!
A liberal’s disagreement with a socialist or social democrat comes down to this: we both seek equality, but the only equality a liberal thinks is worth striving for is an equality of freedom. A liberal’s disagreement with conservatives comes down to this: we both seek freedom, but a liberal believes no one can achieve it alone. There is such a thing as society, and government’s purpose is to shape a society in which individual freedom can flourish. (Michael Ignatieff)
