Are seiko 7009 dials interchangeable with 7s26 dials?

I've received a vintage scrap seiko 7009 watch. While the dial is in good condition, the movement is corroded. Based on how worn it is. I would like to change a movement for the watch. So I want to know if the 7009 dial can be fitted into 7s26 movement since most available 7s26 movements are in better condition.

Yes. 7009 is the predecessor to 7S / 4R / 6R and it exchanges mechanically.

did it fit? are the day/date discs from a 7009 fit on a 7s26?

I've got a 7s26 dial on a 7009a on my wrist right now. They are perfectly interchangeable. 

 

In regards to day / date discs I'd doubt it. Looking at the service manuals they are different part numbers and the date/day combination for 7s26 will change based on the case used, so likely not compatible with the 7009a

    • in general this shouldn't be any change. but in general questions like this it be nice to know the specifics of the watch in other words how was it performing before it was cased up and what is it doing now.
    • just as a reminder this watch is a Swatch group product. This will bring up a problem like spare parts and technical information. that I found some links to some information on when I talk about your watch and some of the technical and basically your watch is equivalent to 2834-2 for which I'm attaching the technical sheets. But equivalent does not mean exactly the same you want to do a search on the group for C07 as we discussed this watch before including the technical differences how it's supposed to be regulated and basically because it's watch group there is no parts availability. https://calibercorner.com/eta-caliber-c07-xxx/   https://www.chrono24.com/magazine/eta-movements-from-the-2824-2-to-the-powermatic-80-p_80840/ https://www.watchuseek.com/threads/h-10-movement-details.4636991/ eta CT_2834-2_FDE_481857_15.pdf
    • 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.
