The Grenade watch looks like an explosive device, but when you flip the lever, it opens to reveal a clock movement. While they won’t actually withstand an explosion, they should hold up pretty well thanks to their Stainless Steel case construction, durable mineral glass crystal and water-resistance to 3ATM.

They’re available in Army Green or Matte Black finishes and come with either a skinny canvas or wide leather and canvas wristband. I managed to find all four styles over on WatchWear.com starting around $125 each.

Just don’t blame me when you get stopped trying to go through airport security with one of these strapped to your wrist.

There are a ton of really great watches in their current collection, and one that caught my eye in particular was the $210 Metal Monte Carlo.

This watch seamlessly connects the analog and digital worlds in a sleek modern watch face. It features a beautiful, clean stainless steel case, and a face that incorporates a small analog dial (with second hand) and a inverted grey-on-black LCD display. The monochromatic backdrop to the watch face is especially striking.

Another favorite has to be the $137 Rosewood, which actually features a case which is crafted from real wood, with each piece linked together using a flexible wire.

I also really like the $179 Emery. This watch is one of a series which is inspired by the designs of classic radios from the 1960s. It really does look like an old radio dial.

These are just a few of the unique designs that their talented designers are cranking out. Be sure to check out all of the cool watches over on the Vestal website.
