I had not heard of that company. I took a look, and they look legit. They use decent Japanese movements in their kits, and on the whole they look fairly stylish. If you plan on buying one of their kits to save money, you should be aware that you can buy watches with those same - or comparable - movements for considerably less than what some of the kits cost, especially if you buy from a discounter like Jomashop. They have Seiko automatics for as low as $90. But if you like the styles of the DIY watch kits their prices still are pretty reasonable, you're just paying a bit of a premium for the fun of putting it togetherHey Mr Pinter!! Have you heard of these guys?

A chronograph is basically a stopwatch integrated into a wristwatch. With a central sweep seconds counter hand, and a minutes counter sub-dial (on the right), this one counts up to 45 minutes. The regular seconds hand is in the subdial on the left.Without looking it up, I have no idea what makes up a chronograph.
