I have the black Monster and have been wearing it for the last few years.
Solid auto watch. I really can't say anything negative about it. I bought mine here.

Can't say anything but good things about that site. They will size it for you too, IIRC. Like the other poster mentioned, there are collars with the pins in the band that you have to keep up with and they are dinky. If you are good with that kind of stuff, it won't be hard to adjust yourself. If you are half blind and inept with tools, opt for them to size it for you.
Mine loses a minute a month leading me to believe that Princeton watches regulated it prior to shipping it or I got an exceptionally accurate one by chance. I wear it 17 hours a day so that helps.
The bracelet is phenomenal at this price point.
The watch is non hacking, the day and date feature is nice, the screw down crown at the four o'clock is comfortable, the lume is bright and long lasting, and the bezel rotates smooth and nice. Mine has been worn daily at my LE job and looks great save for the scratches to the band.
The crystal is not sapphire but mine has not suffered any noticeable scratches. It is a domed crystal so the bezel helps protect that somewhat.
The Monster ruined me from buying watches. The only one that has come close to raising my interest is the Marathon auto.
Regards.
