I wanted to change the band on my Mad Cow from the steel/ti to the rubber band it came with. I've been wearing my Mad Cow in Rotation with everything from my gold Rolex and Panerai, to Breitling, etc. for about a year. It was hard to get the four screws out, but eventually they came out. On went the rubber strap, and the D*i*D screws WOULD NOT GO BACK IN. Nothing I did seated them. Finally I completely lost my temper, put the screw driver up, and started hammering the screwdriver with a household hammer with the watch sitting on some plastic I had handy. Here and there the hammer slipped and marked the side of my Mad Cow. Eventually, some semblence of scews went into the holes where they securely hold the rubber band. Needless to say, this is a watch that will not be getting re-sold at any point.
So the next day, when I was less frustrated and angry, I picked up the Mad Cow and looked at all the marks I had made in the sides of the cases while hammering away, and then I looked at the crystal which was completely unmarked.
The watch, in the meantime, was keeping perfectly good time, as though the hammering had never happened.
So my beat up Mad Cow is now back in rotation, on it's rubber strap, a look I like a lot. I'm going to order a new Cannonball chrono for "dress up" but I have to say that I like my "beater" even better now then I did before.
And if you see any of those stupid questions that I see in my Rolex forums, like, "can you golf wearing your ?" "can you ride your motorcycle wearing your ?" "Can you wash your hands with your ?? on" in some forum or other, please refer them to this post and tell them that while it is not advisable, at least one Ball Hydrocarbon "Mad Cow" owner can HAMMER on his Ball Watch, and wear it to work the next day.
Pretty remarkable watch, from my perspective. Now change the strap changing system so it doesn't take two screwdrivers at the same time, and a Gregorian chant to change a band or strap, Ball Watch!!! I've still got the Hammer!!!!
