If you've been waiting to get your hands on Sony's latest mobile gear in America, today's the day.

Sony has just placed unlocked versions of its Xperia Z1 and Xperia Z Ultra Android handsets up for sale at its US retail website. The company has also added its Smartwatch 2 wearable tech gadget to its virtual store shelves.

Those in the Sony know will appreciate the Xperia Z1's suped-up 2.2GHz quad-core Snapdragon 800 processor, large 5-inch Full HD (1920x1080) resolution LCD screen, and sharp 20.7 megapixel camera sensor. The Xperia Z1 keeps the stylish and water-resistant chassis of the previous Xperia Z as well. Sony prices the unlocked GSM Xperia Z1 at $669.99.

Taking a page out of the Samsung Note 3's playbook, the Xperia Z Ultra is also a phablet of sizable power and girth. Boasting the same 2.2GHz quad-core Snapdragon 800 processor as the Z1, the Z Ultra ups the ante by sporting a massive and larger 6.44-inch LCD screen yet matching its Full HD (1,920x1,080 pixels) resolution. The Ultra doesn't come with its own special stylus like the Note 3, but is designed to let users scribble on it with pencils and metal pens without damaging the display. Sony sets the Xperia Z Ultra's price at $649.99 (for a GSM non-LTEmodel), while the LTE-capable Ultra rings in at a higher $679.99.

Rounding out the trio of new Sony products is the Smartwatch 2. A follow up to Sony's first stab at a smartwatch, this latest gizmo brings welcome improvements such as a water resistant housing, NFC technology for fast and convenient pairing, plus longer battery life. Despite all the promised enhancements, the Smartwatch 2 will sell for $199.99, $100 less than Samsung's Galaxy Gear timepiece.
