LeCoultre Memovox K815

I found this at a yard sale out of the case with hands and dial already removed and some lose bits.  I was able to find where the parts go but I'm missing a bridge screw and at least one gear.  Does anyone have a tech sheet for this?  How about a good spot to locate parts?  Any general advice?  The movement itself is running well  -9 seconds 240 degrees  0.4 error.

Her is what I see obviously is missing. All from the alarm function.

7294 - Alarm setting connection wheel
7292 - Alarm intermediate unlocking wheel
7305 - Coupling yoke for alarm setting

Maybe someone else can spot some more.

BIG BIG thanks HLS.  Because of your help I was able to find all three pieces on eBay for a total w/shipping of $146.50.  I still need to find a gold second hand but I found a silver one that I could try to gold plate if a gold one doesn't pop up. Now if I can figure out where the new parts go I'll be all set.  If anyone sees any other parts I'm missing or has any advice please let me know. Thanks.

That was a fast move ordering the parts. The ones I mentioned is put in these places. 
I was trying to pull out some memories out from my head about the wheel which is in the place where the coupling yoke goes (7305), can't remeber it was two pinions on that one, can it be so that the upper part goes of and that one is actually 7294 put on top of the intermediate wheel?

After a nice dinner and a short snooze, I think the mojo came back.
The part that I previously suspected was in the wrong place, probably are. One can’t really see it from the picture but I don’t think the unlocking wheel bridge (7151) goes on with a setup like this, that part will poke up to much. The bridge should keep the wheels in place nice and flat. 

So, if you pick the pinion off the position where the ring is in the picture you should have an intermediate wheel left in place underneath it. There is a small hole in the pin holding the wheel in place.
The slot milled beside the wheel houses the pointy spring part on the 7305. The smaller of the holes on the 7305 goes in the same place as the intermediate wheel so you have to lift that away when installing the 7305. When the 7305 is in place you put the wheel back.
The 7292 is put in the hole with the flange on the 7305. To finish everything up you place the unlocking wheel bridge (7151) on the whole wheel train. The pointy part on the 7151 should point towards the winding stem. The 7151 is then screwed in place by three screws where off one goes into the hole where the 7294 now is placed.

Well as soon as parts came in I had to move so project was put on hold but now I'm wearing my Memovox.  I still need to find a second hand.  Thanks for all your help.  I could not have done it without you.

Great project! 
 

Id very much like to have one of these old alarm watches. This, the omega or another. Great job getting it going. 
 

If you check the pinion size you can probably find a generic gold hand the right size, or slightly off, to be broached, or closed in a pin vice, to fit perfectly.

    • Getting back to the issue which is us guys repairing or just enjoying horological exploits. The big worry now is how sound is Cousins as company going forward. The of cost if this 8 year legal battle will be astronomical. Cut backs will happen noticed already how the Cousins catalogue is half its size this year. The main supplier going out of business will hit the UK horological community in a big way.    On the Brexit issue it was about a sovereign country being able to make its own laws and trade with any country in the world. I cannot see what was wrong with this. For those who wish to re join the cost would be very high indeed.
    • Yes, it's the same (old) song and it's getting worse & worse;  
    • 🤔 leaving the EU meant that UK was no longer part of the convention and have already been turned down an independent reapplication. I'm pretty sure courts have to be held in Switzerland in this case. There will be a lot more watches stashed away in draws  tbh, folk wont be able to afford to maintain them. Cheap watches will be bought and top end watches by folk with plenty of cash that can pay for service and repair. The expensive once in a lifetime gifts and everything else inbetween will be at the forgotton when they stop working. I know i was being a numpty, get used to it 😄 Anybody that knows will boycott them, but besides repairers who will know. Nope will never buy one, i made that decision as soon as i learnt about this. 
    • although not in this case.  It was the Lugano Convention and its deficiencies that allowed a Swiss court decision in the first place.  This isnt really a Brexit issue at all.  A decision that affects both the EU and the UK should never have been heard in Switzerland. I bet the authorised service centres in the UK are pretty pleased.  It's a massive shame, though; I believe watch owners should be able to choose to have their watch serviced by whoever they trust.
    • Hi guys I think that old hippy is correct, it opens the gates for china to manufacture aftermarket spare parts. considering that they already do work on behalf of the Swiss I guess this decision gives the a little more legitimacy to tool up and I am sure they will take advantage of the situation either with or without the blessing of the Swiss watch industry  Having read about the protectionist machinations of the Swiss in the history of Europe they were the only ones to get fat at everybody else’s expense. I think the outcome could have been guessed at but ,  fair play to Cousins UK for standing up to them.  Now the question,  will everybody boycott Swiss watches and Swatch, no way they will still fill their coffers.  Me I stick with the Japanese once renowned for cheap shitty watches who came good through industrial effort and don’t for get the Russians that most dismiss as low grade crap. Wouldn’t buy a swatch product ever how about you all.? a
