Speeding up a watch movement

I am not really an amateur watch repairer.  
I live in Melbourne Australia and am finally allowed to wake up and go outside again.  I'm 72 and a model railway enthusiast (N-Scale)

This is probably a strange request but I'll ask anyway.  

The latest thing in model railways is to make things other than the trains move also where possible, to get it to look more life like.

On my layout therefore have a guy felling a tree, a hunter shoot a stag that actually drops dead, a coffin lowering into a grave as the bell tolls.

For some time now I have been wondering how I can make the clock on the clock tower actually show the "model" time.  So firstly I am looking for a small witch movement.  For N-scale 10 mm diameter, for HO/OO 20 mm.  The latter seems to be easier to find.  Then the problem starts.  So one does not have wait for 24 hour for a day to pass, on the model time should be accelerated by a factor of 12 or even 24.  On movements with electronics is it possible to feed it with external clock pulses to achieve that?  I also need to bet able to set the movement the correct time so I can synchronise it with the clock in the controller.  

Any suggestions are most welcome.  

Regards

Wolf,  (Melb Aus)

Hi and welcome,  On the quartz watches the speed is governed by the the crystal which operates at 32,768 pulses per sec which is then further cut down via the electronics module (Block).  So by altering the crystal frequency it would alter the block out put.  Its all supposition as I have never conteplated doing it.

Perhaps the attached manual will help as it explains the fundamentals of quartz technology         Cheers

      Setting lever spring

      By mikepilk · Posted

      I would harden and temper (to a light blue). It's so easy to do and only takes a couple of minutes.

      Here is the insert ring for rectangular or elliptical movements: Note that the length is the side with the stem cut out on the spreadsheet (in the picture below this is 15.15: Here is the fake pdf file, again you need to convert to .zip after download to access the FreeCAD and 3mf files.

      Omega cal. 565 - low amplitude

      By JohnR725 · Posted

      as you took the mainspring out what did it look like? It's amazing how much amplitude you can get if the mainspring actually has the proper shape. last week I was doing a 12 size Hamilton and was very much surprised with the beautiful back curvature the mainspring had. Then the watch had a really nice amplitude the group would be so proud it was 350 until I dropped the lift angle down to 38 that drop the amplitude quite a bit below 300. then with the beautiful back curve it still had really nice amplitude the next day. I really wish all my mainspring's look like this as the watch had beautiful amplitude the next day. So many of the aftermarket pocketwatch Springs I see now do not have anything resembling a back curve may be a slight curve and that's about all. They still work but they just don't work as nice as a properly made spring. then Omega as all sorts of nifty technical documentation unfortunately every single corner is watermarked with where it came from who downloaded it etc. very paranoid company. On the other hand I will snip out images like from the document on recycling a mainspring barrel. for instance here's the section on what your mainspring should look like. water damaged a lot of times means rust was there rust on this watch?

      I wondered that?
