I need help putting my movement back together

[Winston]

Hello ladies and gentlemen,

While taking my first movement appart (4216A from seiko), I made a rookie mistake and I need your help. At some point I turned the caliber without noticing that a few parts were loose and they fell without me seeing from where they came.

 

I was wondering if someone could help me figure out how to put these few parts back on the movement:

-810 420 Date jumper

-808 422 Date dial guard 

-873 422 Day jumper

-972 423 Day-date corrector finger

 

Thank you very much, I was not able to find the information elsewhere. I can upload whatever picture you guys think are relevant.

Hi Winston,

Its kinda hard to explain without pictures and the explanations below may not be correct.. just general guides.

Date jumper,    If you put the date wheel on the movement it should be easy to locate where this goes. If the spring is not integral to the jumper like other seikos the cut-out for the spring should give away the position.

Date dial guard,   place the date wheel on, rotate the date guard round, it will fit in only one position. Tips, any chamfers on the holes should fit upwards as these are where the screws will go. Look out for any circular cut-outs as this will be where the date driving wheel/finger or balance jewel will be.

Day jumper.. since you mention this as a separate part, this usually goes on top of the date dial guard.. similar to that you need to move it round and get the holes lined up.

Day-date corrector,  this is kinda tough.. I think it just sits on the keyless works and is held by the date dial guard.

I googled the 4216 as I'm not too familiar with it and I believe that its basically a 4205 (which itself is similar to the 2205) but a bigger size main plate. There are some write-ups on the net about the 2205 and they could be helpful. Kinda of weird that Seiko went to the trouble of making a bigger mainplate when they could have probably bunged in a 7009 or similar.

This not the exact movement you have but it should help guide you to how to assemble

It's a 10 1/2 movies.t used (rarely) on ladies watches which are too small for a 4R36, but larger than the traditional size, it avoids using an adapter ring. Still made as SII NH16.

Thank you everyone I managed to put it all back together
