Our 16 month old grandson loves grandpa's indigo Timex watch.  He loves to see it light up in the dark.  So we got him the Froggie Indigo watch for kids by Timex.  Now before he goes to bed everytime he's at Grandma and Grandpa's house, we all light up our indigo watches.  Our grandson can now light up his own.  Great product for kids.  And it's a Timex!
