Seiko quartz wheels and pinions interchangeability

Recommended Posts

I am trying to fix a Seiko V600. 

The fifth wheel has a broken pinion. I cant find the part which is 701012 anywhere. 

So that got me thinking if Seiko did use some of the wheels across different movements. Or if every new movement they designed they also designed a whole new set of wheels?1 is it the case?

Sometimes if there is a base caliber then your parts will cross reference to several movements but other times maybe there is no base caliber. Remember Seiko is going to make hundreds and thousands of these so gearing up production the and make unique parts for every single one doesn't seem to be an issue.

The website below has a subscription service. One time fee for life. So for instance I take your part number I go there and enter the number in I can get the bestfit number. Sometimes for some parts and some material houses if you use the best fit number you get a part where you may not get the part with the original number. Then you can also look up how many watches use your part and almost none.

Thanks John.

So I bought the BestFIT license. 

Now I am trying to source a rotor for a OME 1336 and I get the best fit number X/9883 and I cannot find an onlinestore that takes orders by bestfit number. Do you know any?

Or maybe the sole purpose of the BestFIT is to help you find equivalent parts and that is it.

For this group regularly that's what I use it for the cross reference purpose.

Then if I need a part I have a local material house that uses the system. Usually I just telephone she is not online occasional do an email. She'll tell me whether she has it or not usually not then she just orders it and if I'm lucky and shows up a couple weeks.

Then here's a website were too late it's out of stock unfortunately. But you can use your numbers on this site.

    • 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
