NH36 Date changing at 4am instead of 12am

Hello everyone, 

My recent mod was looking good until the date change happened at 4am and not 12am?! Is there a fix without removing hands etc. as I don't want to do that cuz I'm really happy with the finish and don't want to risk scuffing dial or damaging hands etc.

Appreciate the advice/help folks.

Hi,

Yes that's exactly how I put the hands on, I've done five previous builds and I've always put the hands on following this method so I'm baffled as to why this date change is happening at 4am?!

Thanks for the reply.

It might be rubbing are you sure the date change isn't bent and that it is seated correctly. I wonder if the dial is catching so look at the dial feet to see if they sit correctly in there holes. Should it have a tension washer that goes over the hour wheel is that missing or if its got one is it good.

Seiko NH movement so no dial washer. As oldhippy says the hands need to be reset for the date change to happen at midnight, as it is NH36 it has a day wheel as well, iirc the day on these changes around 4am.

@oldhippy according to the thread title it in a Seiko NH36 caliber, that is why I answered under that assumption.

I forgot it was a Seiko (old age is a bugger) 🤣

Is that little circlip in it's place and is it flat and not bent.

Hello folks, 

I didn't get time over the weekend but I did manage to reset the hands yesterday and the date change is now working correctly. However, I did scuff the dial a bit 😞

Lesson learnt - get it right the first time! 

Thanks again.

    • Your general point is well made, but in my case I was talking about the teeny 0.2ml vials, e.g. 9010 for £6.87. This is considerably worse value for money unless this is all you need, in which case it's great! When you multiply by the ~5 different kinds of lubricant you need, it makes a big difference for a beginner.  0.2ml is plenty for a leisurely tinkerer as long as you're careful not to spill it! I made a little stand for the vials by drilling holes in a plastic bottle top. Then I carefully transfer a drop or two from an upright vial to a covered oiling cup using a large oiler as debated in another thread here.
    • neverenough, Upon further inspection  (10 power loup) I found that there  was a slight bend in the frame there the lower jewel was fitted. Very thin brass do to all the metal removal to make room  for the parts. I must have done that then I pressed in the new banking pins.  In the process in flatting out the area. Reinstall the jewel and see where I stand. Dave
    • A few years ago, I started out my workbench with a $50 oil kit from ebay with tiny quantities of 9010, HP1300, 8200, 9501, 9415. But the seller was from my own state and known personally by a professional watchmaker I'd taken a starter class with. She doesn't seem to still be selling kits though. This was for me, part of the initial investment and a development phase of "can I do this work, do I have the patience and dexterity." The economics of my quantities received vs the price originally packaged volumes were not really a consideration because I wasn't buying for long term or high throughput (as a pro would need). It was simply a matter of spending $50 on something I was uncertain to succeed at vs spending $150 with no greater guarantee of success. Just adding hobbyist perspective here. And I was fortunate that a professional watchmaker could vouch for my oil repackager.
    • I hope I took enough pictures. I am now going to clean everything and I am pretty uncertain about my ability to put it all back together.  The basic movement should be ok with likely some frustration when putting the big bridge on. But both the calendar side and the automatic parts will be stressful. Specially since everything is so tiny compared to the ST36 so many more parts This 2 will be of great help.  The Miyota site actually provides them This part is called “date dial guard” in the Miyota chart. As you can see there is a wheel and some kind of spring/jumper on it which I don’t think I can remove.  I also don’t see them in the assembly - disassembly chart.  Do you think I am correct it is supposed to stay together and I shouldn’t try to disassemble it further?
    • I have often to reshape stones, for example when I need to replace 'rolled over' or burnished type stone with a modern one. The other case is when a wider pallet stone has to be sized to tight fit the slot in the pallet fork. The tool that does this jobs is this kind of diamond disk. Grit 1000 or 800 is perfect for the honing. If the stone height is to be resized in the way Jon did, this will be enough to put the disk (the big one) on the table top diamond side up, put the stone on the disk, press it with finger and move it forward-reverse for a while on the disk surface, then try the height. If one is carefull and take measures  not to grind the surface bent, this will take no more than minute to resize the jewel. The same way I use to resize the pallet stones.  If a stone edge have to be rounded, then I turn on the top of a rod a 'nest' to receive the stone and glue there the stone with shellac, then while the whole thing is rotated, use the disk as a file to shape the stone.
