Hello again ,

just got a Seiko V158A with the day and date function . Broken glass so fitted a new one. Had trouble getting the crown and stem out but it came eventually.  

I may have bu**ered it up by changing the date and day in the forbidden hours between 9 and 3.  Now the date and day function cannot be adjusted the quick way ,ie pull crown until first click then anticlock or clockwise to set day or date. Now nothing happens on first click . The second click position still works to set the time  

 Is it fixable and how easy for a complete amateur to fix.?

I don't thinks so. Seiko like other manufacturers have a protection that allow calendar quick set at any hours. That is done with the fingers of the day/date wheel being flexible, see picture.

If one tries to set the calendar while the finger is pushing a teeth of the date ring or day disc, it bends back and nothing breaks. However, for whatever reason, the user manual still warns against setting the day or date around midnight.

That being said, the quick setting wheel itself (not pictured) is fragile, and most likely it has broken somehow.

Some people finds that easy, some strugge. But everyone needs parts to repair. 
If you care about this watch leave it alone for now while you practice on something else of no value. See below for recommendations. Also, if one is serious about learning proper watchmaking, the best way is to engage in the training offered by our Host Mark Lovick at watchfix.com

Hi As an addition to the words of wisdom from jdm I have attached the technical sheet to give you some idea of the complexity of doing it your self. without the proper tools etc this is a non starter . If you wish to have a go do as jdm said and enrol in the courses and gain some experience then doi it.

Fixable depends upon what you did to it?

This is problematic? Shouldn't have been a problem to get it out and if you pull too hard you might have damaged or relocated things in the places where they're not supposed to be.

Then this looks like a solar watch? It adds in some additional challenges definitely not a beginner's watch if you are thinking of disassembling it.

Hello all , 

 sorry about the delay in replying. 

 Using the PDF instructions watchweasol (thanks) posted I found the problem with the seiko solar v158a. The second intermediate wheel for date setting had been forced off its axle(?) and shifted slightly to the side and the date dial guard had a slight twist. 

 I found it quite easy to strip down to that level and rebuild but didn't go into the geartrain area. A lot is plastic clips that a beginner can easily follow.

Its now working but I will keep shifting the date/day to see how long it will hold.

No photos as I dont have any means of taking photos clear/sharp enough for now

      Omega sweep second pinion friction spring - correct tension IS important

      By TimeWerks · Posted

      Thanks for this post MikePilk, I just came across a similar problem with an Omega 1022.  The problem I had was the seconds pinion spring was bent out of shape and did not even engage with the wheel properly, so the seconds hand was not moving at all. (no power loss though :) I removed the automatic module so I could access the spring and work on it. Once I bent it back close to the right shape, I experienced the same problem you reported about power loss.  Many tweaks later, and the seconds hand is moving properly again, with amplitude back to good numbers again. Cheers

      After cleaning up the pivots, I made bushes on the lathe. At this point I've pressed in 6 bushes (3 sets) and the wheels turn smooth. What I can also tell you, is that I'm not looking forward to final assembly. Getting the pivots aligned seems to get exponentially more difficult with each wheel that is added.

      Greetings from Whidbey Island.

      Islands are interesting places to live depending upon their size and other factors. This is a bigger island and it has a bridge to get there at least on one end. It's also big enough that you don't have to go someplace else to get things typically. It can be a problem if you get a job in Seattle though. Yes I've known of people who commuted from the island to Seattle for a job and I don't quite remember how many hours it took but it took a long time. So basically islands are nice if you don't have to leave very often.

      What's your thoughts on this Rolex Sea-Dweller, ref. 16600, calibre 3135 project?

      Thanks @JohnR725! Everything you say makes a lot of sense and is encouraging to read.

      isn't it nice to have a decent case open or when the case doesn't want to be opened? In the case of a Rolex watch that supposed to pass specific water resistant testing you probably do need to tighten the back down. But they shouldn't be tightened so much that they risk stripping the threads out. Then the other problem that comes up is the gaskets can start to disintegrate and then getting the back off can be quite a challenge unless you have a really good tool and perhaps some penetrating oil to loosen things up. Yes really nice case marking. When I was in school we were taught to mark the cases and  the American watch and clockmakers Institute even had a? So if you joined at one time they would give you an identification number. They were explaining or giving an example of if the watches ever found in you have a unique number they can perhaps figure out the history of the watch or identify the body it's attached to for instance not that that probably comes up that often. So you got a unique number and even made a special metal stamp that you can purchase. It wasn't a super big aggressive stamp but still it left a mark in the back of the case. Then I heard from people at work on Rolex watches they were using a felt pen indelible but later on they decided that was bad because apparently the ink could release  chemicals although it seems like once it's dry that shouldn't be an issue. Then of course today was nice is you can keep computer records sealed have to mark anything at all I personally find it's best to leave no reference behind that you were even there. Especially when you have a beautiful watch that has no markings at all and now it has your scribbling all over it not good typically if there is a typical and watch repair?  a lot of minor repairs you don't need to do a complete servicing. But beyond a certain point you're going to have to take apart a lot of stuff you're going to disrupt the lubrication even if it looks perfect right now and yes you might as well just go ahead the service the whole thing. also in a watch like this where a lot of things seem to be going on the complete service would be better then you'll know exactly where you stand versus dealing with unknown mysteries for prior repair.
