Recent discovery 4006-6027

My father purchased a (Aug 74 vintage) Bell and wore it for ten years, after which it was put in a drawer as he had bought a Seiko quartz. After my mom passed away in March, this watch resurfaced (I thought it had been long lost). I started it up, and it's been running fine ever since and everything works as expected on it. It runs (resting on it's back) about 1 1/2 secs fast per day. yay!
