It's a Seth Thomas clock that was made around 1950. It has a bell that rings with the traditional 4 hour watch on a ship.
1 chime at 12:30
2 chimes at 1:00
2 chimes, then one chime at 1:30
2 chimes, then two chimes at 2:00
etc.
At 4:30 it starts over at 1 chime.
I haven't heard this clock chime since it was in my parents' house when I was a child (quite some time ago).
It's basically been sitting in a closet for about 20 years. The spring that drives the bells was stuck, and I sent it out to be reconditioned a couple of weeks ago. Just got it back and it works great.
This may seem silly, but those bells are soooo cool.
I've got another old clock that's even cooler. I'll post that one later.
