I have one, in excellent condition, Precista PRS-10 G-10 G10 General Service Watch.

This was Eddie’s improvement on the CWC G-10 Watch by adding a sapphire crystal, screw down crown and screw down caseback. I also believe it has a 10 year battery life.

I replaced the spring bar with a better quality Swiss spring bar. The ones that it came with were not the best.

I’ve had it for about eight years but when I’m not wearing it, I pull the stem out so the battery should be still good and strong.

The only reason I’m selling it is probably it hasn’t been worn more than 10 times since I bought it.

I can’t find the original strap that came with it, but I will include a straight nylon strap for it.
