Hello everyone!  Picked up a small bunch of parts from an estate sale awhile back and inside was a box with a Seiko 6106-7689 completely torn down.  I thought the watch was very unique and decided to piece it back together.  The movement is now back together and running very nicely, but when I fit the day and safe wheels that were in the parts box, the day and date don’t line up in the dial window.  My question is, because the crown is at the 4 o clock position, are the day and date wheels specific to the 7689 because they are offset of the crown?  Any help would be greatly appreciated!

Well they're either crown at 4 or crown at 3. I would remove the dial and see if the day and date lines up with the crown.

It could also be a mix and match... not only from the 6106 but 6119 (and most 61xx) models. Do you have the full watch including case, caseback?

Is the day wheel part number 870610?  

Yes the noted type of case. day disc is also a good name for it.

Yes I have had this issue in the past. The day & date disks look the same but when fitted do not align with the dial window. I have had some that are just a tiny bit out which is annoying. Luckily I picked up a job lot of dial & date disks off eBay a few years ago and have been lucky to find ones that eventually fit.

Anilv, yes I do have the complete watch with caseback.  The case back does indicate it is a 6106-7689.  Walsey that is a great piece of information that you have there.  The disks that I have are different numbers so I guess I will be on the hunt for those numbers.  Thanks everyone!

The other method with the day wheel is to loosen it with screwdriver by pressing on the star wheel underneath. Realign it. Then gently stake it closed again. 

I have done this method when even the correct fitting wheel wasn't aligning. 

Weirdly not much is spoken about this method in the Seiko community despite me having a problem with the wheels on number of ocassionas mechanical and quartz. 

The date wheel sadly needs to Be replaced or in rare cases repainted if it is NLA or extremely rare (such as omega Moon phase etc. )

AlexeiJ1 that is a very interesting and creative method!  Ill have to find some damaged day wheels to maybe get some practice doing this if ever the situation arises!

      All watches are repairable a few oven duff tools knowledge skills. But I was just agreeing that it be easier to get a movement.

      About repair watch's jewel.

      First of all, thank you for the pdf file of the book on how to replace a gem. So, if there is a problem with the ruby in the movement, should I buy a new or used movement and replace it? When I watch videos on YouTube of people fixing used watches, I feel like there should be a way to buy a gem. Is there no way to buy it?

      Parts sourcing for FHF 180 movement

      I suppose @donutdan is not forced to earn his living by repairing watches.  I suppose he does it as a hobby and wants to gain experience, to get better in watchmaking and time is not the issue. Then @donutdan should rather try to repair the damage instead of swap parts from a maybe intact other movement. Swapping parts is not watchmaking. And often swapped parts are not the expected solution of all problems. All mentioned damages are repairable. Frank

      Yeah I figured that one out when I googled and realized that my spindle is actually from Horia. It's smooth with no screwable cap.

      I am puzzled by something a snipped out something from your image and what exactly disassemble tell us? my confusion is the symbol for FHF looks like image I have below year symbol as a star and righted this instant are not finding what that means? I suppose we could use the fingerprint system to verify it really is what it claimed to be. Size itself is really interesting there's almost no watches in that particular size. Then were missing details in the photograph above like diameter of movements to verify it really is the size and are missing the setting components.   went to the bestfit book looking at the symbols didn't see it. Look at the link below I did find it back to the bestfit book and yes it really is there https://reference.grail-watch.com/documents/history-of-ebauches-sa/ then bestfit book says lists the size as 10 1/2. one of the problems with vintage watches is finding parts yes a donor watch would be good.
