Nice watch. the Maltese cross thingie, is a wind up stop Howards used them a lot, when you wind it up it will move until the last cog then stop preventing overwinding. You can see in the photo how it works on a Howard.I am unable to observe any relative movement of the maltese cross thingie. Can anyone shed some light on this?
Thanks RL.Nice watch. the Maltese cross thingie, is a wind up stop Howards used them a lot, when you wind it up it will move until the last cog then stop preventing overwinding. You can see in the photo how it works on a Howard.

Thanks LC.I'm not a watchmaker but I have a similar watch with a stop wind mechanism. It's 23 jewel caliber 19.95 (previously posted). It was not running when I got it. The intermediate winding wheel was broken and half the maltese stop work was gone. Watchmaker fabricated a new one.
There's a lot of good information about Longines railroad watches in the October 1998 Bulletin "Railroaders Corner" by Ed Ueberall and Kent Singer "Longines Standard Watches."

When I wind the watch (it keeps superb time BTW), I am unable to observe any relative movement of the maltese cross thingie.
Good to know, luvsthetick.I have seen watches that are missing the lever on the arbor that activates the star wheel. You star wheel may also be hidden when it moves, I am not familiar with your movement.

If you want to know if it is missing the lever tongue you can get something like a toothpick or carefully use a screwdriver and see if the stop work revolves, if it moves around there is a good chance your lever is missing or broken. Then you won't have to take off the barrel bridge. If you do make sure the mainspring is let down first before removing it.I'm tempted to remove the barrel bridge for a look-see but maybe it's best that I leave it alone lest I bugger something up. Might be a good idea though for me to keep an eye out for a parts movement just in case.
RL ~ I checked the motion of the stop works wheel as advised. It rotates freely in both directions. This free spinning occurs whether the watch is run down or fully wound.If you want to know if it is missing the lever tongue you can get something like a toothpick or carefully use a screwdriver and see if the stop work revolves, if it moves around there is a good chance your lever is missing or broken.

Here is a photo pointing to the part missing or broken the lever tongue is sticking out so that would be the part broken or the whole part might be missing. The watch will still work fine without it.RL ~ I checked the motion of the stop works wheel as advised. It rotates freely in both directions.

LC ~ from this can you tell which component is broken or missing? If so I hope you can identify it for me on the pic which you posted above.
Continued thanks RL !Here is a photo pointing to the part missing or broken the lever tongue is sticking out so that would be the part broken or the whole part might be missing. The watch will still work fine without it.

Can't tell which part of your watch is broken or missing, but here are photos from my watchmaker. He told me mine was "..missing half of the maltese stop-work." The drawing is from his CAD fabrication of the new part.LC ~ from this can you tell which component is broken or missing? If so I hope you can identify it for me on the pic which you posted above.
It looks different then what I am use to seeing but I see how that might work so yes that would be the lever tongue, If that is what is in your watch. It still would be broken or missing. If it is in place you can not turn the Maltese Cross, also know as a Geneva stop work ,also used in some clocks.For RL: is the red arrow pointing at what you call "the lever tongue"? If so, would that possibly be what's wrong with viclip's watch?

Yes I think that is the lever tongue you have the arrow pointing too, or maybe a better word would be a finger. Like I said I have never seen one like that but there are a lot of different ones, so if it works that is great. You can search Geneva stop work, and even see how to make one with the right equipment.Here's the photo pointing to what may be the lever tongue.
I would agree with you it first looked like a winding click me, but I mistook what LC was saying as it being the part that used in his watch by the watch repair man for the Maltese Cross, stop. So you are probable right.The red arrow is pointing to the click.
Further to my previous post herewith reproduced, these Zenith Extra R.R.56 watches were supposedly made in a total quantity of 1000. Five hundred came with the "Boxcar" Canadian dial, illustrated above.Zenith Extra R.R.56
I've been looking for one of these puppies for a while, one finally followed me home:
