I have found the most awesome idea for a holiday gift this year - TOCS Watches
Featured as one of Oprah's O List, holiday edition, the TOCS watch line features bold colors, glitzy designs, and best of all some of their models feature solar power with a battery backup that never needs winding or replacing.
They remind me of today's version of the Swatch watch when that brand was the newest and biggest thing when I was in high school. My favorite is the Ani-Digi Solar Alarm Chrono model. I think it looks so sharp and I love the solar aspect. Very eco-cool. They come in a number of cool colors - I even saw a transparent one.
Here is some info from tocswatches.com on this solar model:
The hottest model they have selling right now is called the glitz. It has very cool stylized numbers on the dial - the 8 is the biggest number and has sparkle. Here is a picture of the analog round glitz model. As you can see it would be a very hip Hanukkah gift. Purchase TOCS online. They range between $45 and $60.
