This is my personal watch that I obtained when living on Seymour Johnson Air Force Base as a kid. I used to wear it quite a bit, but have not for decades since. I have had it stored with my other old things, so it has been at room temp and out of the sunlight all that time. I am not a watch technician, so I do not know anything about the movement, nor how to access it. I've been told it is a Benrus, but not having someone actually look at it hands-on, I have noted it as possible Hamilton too. What I can tell you is that it runs when I wind it, and the hands still glow (NOTE: Did a time test, winding watch about 4 half turns. Set it to my computer time at around 4:00pm today. It is now 7:30 and it is still running, and dead on with computer). I can see the illuminated hands, but the small triangles are faint and hardly visible at all. Can't recall if these were radium or some other luminescent material? The band is original too. Overall, a great old watch that is clean and in very good condition as shown. Zoom in and take a look at my photos to best understand the overall condition.

Good luck!
