Well I have seen some springs but that.s the best yet as Nicklesilver said "toast".  The double ended key is from a clock with a brocot escapement (visible escapement) and the small end is used to adjust the pendulum length from the front. There is usually a small hole above the 12 marker and a small arbour to raise or lower the pendulum.    I have attached a picture of what the spring should look like.

If you order only the spring u will need dimensions from the Horolovar 400 day clock repair guide. Or from anywhere else if you can get it. You could take the measurements of the existing one but because the spring is twisted it is probably a bit shorter now. You will need to post a picture of the backplate for us to identify your movement. I could try to scan the right page for you but, I am not an experienced guy, my first 400 day clock is still on my bench waiting for me.

Hi when you come to assemble the suspension  be very careful with the spring as they kink easy, attach the top and bottom blocks as per the drawing as per page 179  5E (use Horolovar springs as the book is based on their research)  and when satisfied they match then fit the fork. Once satisfied assemble the suspension to the clock and fit the rotorary pendulum and set up.  If you have the tool as old hippy mentioned it makes it easier as you are able to make miniscule adjustments.  Make sure the clock is level and the pendulum is directly on center at rest above the cup. On page 56 there is a grid for you to copy and use for setting the overswing / beat. Once you have set it up and working you will be hooked on 400day clocks   I love them  and have several plus some quartz ones. The wife likes them  they dont TICK  TOCK.

Be sparse when it comes to oiling the movement. They perform better. A good tip is to oil the inside of the pallet fork on each side where it makes contact with the stem of the pallets, nothing more then using your fine watch oilier should be enough.  it also will prevent any fluttering. (fluttering) when many escape teeth escape at the same time.

Have ordered the spring I have just got to figure out how to get the pin out at the bottom without causing any damage my wife is the same no noise and no striking in the middle of the night?

If you mean the pin in the bottom block, there is no need to remove it, just unscrew the two screws, remove the old spring, insert the new so it is touching the pin, make sure it is all proper to the diagram in the book and screw tight. I found a good way of fitting these springs and screwing it tight was to use my watch vice to hold the blocks in, Be very careful with the pallet fork when screwing it tight do not kink the spring.

      First movement = First broken movement

      By Terrinecold · Posted

      Thank you for the advice.  Actually I have already ordered a replacement one as soon as I broke the setting lever screw.  It is supposed to arrive today or tomorrow, I got it from AliExpress for $27.51. In the meantime this Sunday I got from amazon the cheapest mechanical watch I could find (a pocket watch with a 2650G movement).  That movement is now sitting disassembled and waiting for reassembly.  I have to say I found that movement pretty ugly compared to the ST36.  The fact that it is skeletonized and center second made it interesting but all the bridges feel very bad quality. One thing which happened with this one (due to the skeleton nature) is that I had trouble removing the hands with my presto tool (I have levers on order but not arrived yet).  I bent a bit the little retainer (the part at the bottom of the picture).  Then later on I couldn't find the cannon pinion.  I finally found it it was in the hour wheel.  I must have pulled it out a bit initially and then oil kept it in there. The other thing which happened is that when I tried to open the case back which the back crystal (plastic, glued) came out.       Anyway tonight is reassembly time for this one. I also have an NH35 and a Mingzu 2813 on order. One question:  I was thinking about getting some old soviet movements which I see on ebay for pretty cheap.  All that to keep practicing and hopefully learn not to break anything before I start trying to service a real watch.

      The ST36 isn't an expensive movement, so it might be easier to just get a replacement for parts. Here's a listing in the U.S. for $33 + $3 shipping. Once you get current movement running you can tackle the tangles hairspring without the pressure of making it worse.   https://www.ebay.com/itm/353824212893?itmmeta=01HYDN4TGZSXFCW4TXZ2THH0C1&hash=item526191079d:g:sT4AAOSwHidhcQO6&itmprp=enc%3AAQAJAAAA8Jw5K76smZgFGzM5ubLY769v%2B6EbBphCYo99M48gxLxxMjir9tRyn32O8Q5AgmKh1aKUP%2FfaCOIz8a7YMGkflhGWus7BDQIzrs45yo8NCZ66Jmti1Qli2%2BjaAm%2F8Ogg81F17LdC5Ulu54cnXSOCtaMkQcp03pcluBqTAuZPxbYwkrOC38sb%2FtlDewlZBOhjtA7pZTTMAql7hFKbrkc5RyF%2BtGL2%2Br9BS7mzgd%2BxdDF08HcVn6rvOawDjEbMPs9mYSegv6DVnSoiYYpMGzPJE7Qyd782Brjl05GQTL9MzpFuWrQvUTNxyY5%2BNQi18XTmf4A%3D%3D|tkp%3ABk9SR8yok7XzYw

      It appears to me that you have overlapped the hairspring.  Hard to say for sure with the pictures you provide.  If so, it is one of the easiest hairspring fixes.  You will have to remove it from the balance cock and the balance wheel to do it right.  There are videos that show how this is done.  Off hand I dont recall where they are. Having said this, preforming this repair is advanced work.  Put it aside and come back to it in six months to a year.  Otherwise, you might make it worse.
