I have two 714 SM glasses whole black ones and blue lenses with Havana frames. Both perfect as the first day, although sometimes it's convenient to have a precission screwer. Happy with them both!
I bought one of these about 10yrs ago. 3 months after owning it, I got a little sand from the beach stuck between the carbon fiber slide and the track. (Didn’t drop it in the sand. So must’ve been from my hands while buying a snack.) Sliding it open has been a struggle ever since. So, I gave up on using it. So, for anyone reading this…be careful not to get dirt or sand in that track….and use a spare wallet for your beach days.
Thanks for the review. Silver is a soft metal and so it will scratch. It will also oxidize. I'd recommend a good jeweler's cloth before each wear if you are concerned.
