Seiko 8F32 Movement

[carl]

Good Afternoon everyone

 

A friend has a Seiko perpetual calendar with an 8f32 movement. She took it back to the high street Jewellery chain store where she originally purchased it to have a new battery fitted. They informed  her that the watch "was dead". When I removed the back the first thing I noticed was the lack of battery. On closer inspection I noticed there was Damage to the coil and after taking a closer look at things there seems to be damage to the circuit board. I am aware that these movements are obsolete and are no longer available nor is the circuit board.

 

Unfortunately I know very little about how to repair quartz movements other than how to change them. Does anyone know if there is a modern equivalent to the 8f32 that is in production that could be fitted as a replacement. 

 

The watch has a lot of sentimental value to my friend as it belonged to her husband and she would like to give it to her grand son.

Hi Carl, welcome to the forum.

 

It is so so so so easy to break these movements and extreme care must be taken when changing the cell.

 

 

The parts are becoming very hard to get hold of but some suppliers may still hold them.

 

Alternatively, if the watch is sentimental, you could purchase a second hand Seiko with the 8F32 movement in (even if the case and strap are different) and change the movement over. 

 

Just a thought.

Cousins show both the coil and the circuit board on their website.

Not an easy job to be fair. The circuits are secured with very very tiny philips style screws and sometimes are quite tight.

 

It's also noteworthy that the winder stem should be pulled to first position before removing the circuit and kept in that position until the new circuit is replaced.

 

There is a service sheet available on the Cousins site which is quite handy.

Thanks for your input. I think I will keep my eyes open for a second hand movement.

for those of us who answer questions on this board I appreciate that you looked up the subject similar to your watch. it's amazing how many questions keep getting asked over and over and over again because no one bothers to look to see if anyone else had the same question.

reading the previous questions and answers is fine but hijacking the discussion is not it may lead to zero or near zero answers. so the original question is not the same as the question you have. Your question appears to be identical to another question that somebody asked and that persons never been seen again? But they did get an answer is posted below.

so the question you're responding to with the exact same problem is what is the stem number and it is this 0351196.

I've also attached some PDFs the owners manual is interesting? Is not overly helpful because it assumes you will return the watch to them for the battery change. But I also have a battery change sheet which explains the setting and the service manual which also has setting instructions.

So I have a problem with a 8f32 movement. I replaced the battery without any problems but when I went to reset the watch, it had been sitting for several years with a dead battery, it didn't reset to 1. I know that the year for 2024 is 4, month is 7 and  in this case the day was 12 (Friday). I repeated the steps to reprogram the  date several times with no success. It's an old watch that belonged to my late father-in-law, so it has a lot of sentimental value. Any ideas are greatly appreciated

So what happens when you short the AC and then the Ø to the Battery?

[Mark59]

Well I seem to have missed that step, oops

I'll be trying that out tomorrow, thanks Andy 

[Mark59]

Well I didn't wait until tomorrow and everything went great until I got to the "day " no movement when I shorted it, so I started over and got the same results.

Can you confirm you're using the correct contact to try and set the date.

[Mark59]

Yes, those are the ones that I have been using. They all work fine except for the day.
