24 hour Model ID

Greetings all!

As my handle suggests I happen to collect watches of the 'purist' 24-hour variety, I was able to obtain this particular one not long ago, and was not able to find much information other than it was manufactured in 1960 (code M0.)  It has run flawlessly thus far, keeping very good time, and the hacking feature still works. I have not attempted to remove the case back to identify the movement (yet) as the facets for doing so appear to have been chewed up in places; I do not wish to add to the damage. It will obviously require some work.

Anyone have an idea as to what model this may be?

Can you post a picture of the case back??

Thanks for the quick response!

Is the reverse. As it is basically illegible, the text is as follows:

BULOVA / (star) Stainless steel case / Anti-Magnetic / M0 101386 / waterproof / shock resistant.

I really need to get a camera with a decent macro lens. As can be seen I have been hesitant to attempt to clean the grime off the watch case as well, as I am certain that the term "waterproof" is relative.

Can you take the back off and post a pic of the movement?

Is there a recommended method for doing so?

It is difficult to discern from the photo but the flutes on the case back have been damaged by what appears to be someone's attempts to get it open.

The case back should unscrew, you may need a case opener to get the job done.

It is not a Military watch, but it does appear to be a factory made Bulova.

The dial looks like something Bulova may have produced...defiantly needs more study...

M0 - so that's 1960.  Interesting.  I have an Elgin 729 from around then, also 24h dial, also definitely not a military watch, since the case is gold filled and there are no ordnance marks.

Was there a fad for 24h dial watches around then?  Gruen made a watch with windows at each hour, and a dial that toggled back and forth between 1-12 and 13-24, and I think it's from around that era.
