Advancing the day with the crown - Seiko 4336

Hi, it's my first post here in watchrepairtalk.

I'm trying to get a Seiko 4336 quartz working again and having trouble with the date setting mechanism. Although this is a quartz watch I believe the parts are similar to mechanical Seikos of the 70s era.

I'm sorry I don't know the part names. I have the technical document for this movement but the part names are not clear on it.

Anyway, when turning the crown counterclockwise the gear on the right doesn't engage the gear on the left (in blue circle), which should turn the day wheel. I can get the left gear to turn partially if I align it just so, but it won't even make a complete revolution. Shouldn't it turn continuously as I turn the crown? I can't work out if I have some sort of alignment problem or if the parts are worn, or something else. I thought maybe it would work properly when the day wheel was in place but no dice. I should add that I didn't ever take these parts off the watch when doing my clean and so on.

Welcome to the forum.

Difficult to see from the photo but it does look like the 3 pointed star part
of the setting lever isn't seated correctly and does look a little worn.

It also depends what's happening with the gears underneath that rotate it.

What's it made of?  It looks a bit like the notorious plastic "date corrector" on LordMatics (cal 5606) 

They may not look it but they are metal.

Ya sorry you can't tell more from the photo. I have a video of this but I can't upload it here.

I also felt like the three point wheel wasn't seated, as I found myself pressing it down with the tweezers all the time. I should probably just poke around and find replacements for both of those gears - pretty cheap if you can find them.

I'll double check how everything looks on the other side, but from everything I can tell, the mechanical function of the watch is fine otherwise. Thanks for the reply.

The setting lever is a complete unit with the 3 pointed star gear so isn't available as a separate item.

The 5 pointed star is part of the calendar plate so again not available as a separate item.

      A lathe with indexing that won't break the bank?

      By JohnR725 · Posted

      interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.

      Lab Coats

      Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything.

      Chinese tools debate

      By Titanium · Posted

      Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.

      I found this string about this problem. I've not gone through it all, but I believe it also mentions making a spring. If not in this string, the info is online.
