GFB HYBRID TMS Dual Port 15+ Subaru WRX / ForesterAll The Performance With The Noise! The Hybrid valve is back! In 1999, GFB's first Hybrid valve pioneered the dual port design, which was so successful the technology has since been adopted by most other brands. By "staging" the two venting outlets, at low valve lifts most of the air is recirculated. As the car is driven harder, the valve opens further and more of the atmosphere venting port is exposed for a louder sound Installation Instructions This

I like it
Color: grey, Color: grey
It’s not expensive but well made. The tack thing doesn’t spin. Idea for daily wear with a nice look to it. I gave it a 4 because the tact thing doesn’t spin and I like a larger watch face. All in all I may buy more as fashion watches for daily use.

Not water resistant
Color: silver black, Color: silver black
Have had it less than a month, shower and swim with watch on. Water is under the face. Very disappointed in the quality, I get it is a relatively cheap watch, but quality should be better than this. Will never buy again.

Water is getting into the watch.
Color: silver white
It’s a nice watch. I own pieces from other brands, and I stopped wearing this one for about a month; when I decided to put it back on, it was still running. I found this odd, since it’s supposed to be an automatic watch—meaning you need to wear it to keep it wound and functioning—and it supposedly doesn't use a battery. Another thing: every time I wash my hands, water gets inside the watch, even though it’s rated for a depth of 30 meters. I have my doubts as to whether it’s truly an automatic or not. Does anyone else here own one?
