Help with Zodiac caliber 86 day/date adjustment not in sync


Recommended Posts

Hello all, I just got this Zodiac 86, it was running but slow and movement was very dirty. So I was taking movement apart and clean it. During cleaning process I found out mainspring broken. When I assembled the movement back and realized that when I set time the date moved accordingly but the days never move at all. Removed a dial and test without dial and found out the 3 screws that hold a plate of days disk align with the clicker too tight days disk couldn’t move. When I untight those screws when move stem to make days disk move the clicker passing thru days disk tooth and pull it with it. So when clicker had to push back the days go back to the same day instead of move up 1 day.

 

First question is how can I resolve this problem?

 

Secondly where in USA that I can buy new mainspring to replace this movement.

 

Thank you in advance for all of your advise and suggestions.Adjustments.jpgAdjustments.jpgAdjustments.jpgAdjustments.jpg

Mainspring can't be changed. You need a new barrel with mainspring . Zodiac use a sealed for life barrel . Problem is they are rare and superhard to find. And 86 use a thinner mainspring because they are 36000 Hz movement so can't use a 72 or any other barrel.

Wow, I am so unlucky then. So it’s very hard to find seal barrel mainspring to replace it?

And I will remove the jump click and check on that area. Everything from that clicker and days’ teeth looking flat no wobble at all.

I will look into these area when I get home today.

Thank you all for suggestions about mainspring too. Stay safe y’all

    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
    • Once a movement has the dial and hands put back and it is recased, would you expect the assembled watch to have the same amplitude as when the movement is in a movement holder and is without hands and dial? Thanks
