Seiko 106334

[stebass1]

Hi All

 

I have a seiko 106334 mechanical watch which was my grandads.

 

The watch is no longer winding the crown turns but there is no tension and the watch will not wind up.  I have taken off the back and taken the stem out, thanks to Mark's video, but then I am at a loss at what to do next to get it working again.

 

It looks very clean inside as it has been serviced a couple of times since I have owned it.

 

Would really like to get it working again as it does have sentimental value.

 

Any advice would be much appreciated as I am a novice and have just purchased the basic tools to try to tackle this.

 

I have found the videos very useful so if you can point me in the right direction I would be very grateful.

 

Look forward to hearing from you

If the watch is hand-wound, i.e. there's no large rotor blade inside it (for an automatic), then it sounds as though the mainspring is bust.

 

If it's automatic, i.e. with a large rotor blade inside, which swings from side to side, the mainspring can't be fully wound by hand - then it will be some other fault.

 

Post a pic of the movement - it's always helpful.

 

And welcome to the forum!

Hi Will

 

Many thanks for your quick response.

 

I can confirm that it is hand wound and not an automatic watch.

 

is it easy to replace a mainspring for a beginner? I have invested in some basic tools as just being quoted ridiculous pricing to have it repaired, which is probably more than the watch is worth.

 

I have a bit of a watch obsession and have several pieces, nothing special, but this Seiko of my Grandads, I would like to wear it again.

 

Are there any videos on the site relating to a main spring replacement?

 

Appreciate your help with this.

All depends on your definition of "easy"! There are a few YouTube videos of watch disassembly and assembly - including fitting a new mainspring into the barrel. It's probably not for a beginner, but if I were you I'd look at a few of the videos to get an idea of what tools you'll need and how you need to go about it.

 

If the watch has sentimental value for you, then it might be better to have a first run-through on a scrap movement that doesn't matter. That way you'll get the experience of doing it without worrying that you're going to break or lose something that really matters to you.

His Steve, welcome to the forum. :)

Wills advice is sound. I would strongly suggest purchasing the same movement or old watch from EBay. It shouldn't cost too much, and what you will learn from taking it apart and rebuilding it a couple of times will be invaluable. Once you are comfortable doing it, and have acquired the very light touch required, have a go with your grandfathers watch.

Ditto, and the advantage that if it is the main spring you might even get the replacement part you need with the old movement from ebay!

Hi Stebass1 , The numbers you gave sound like the serial # ..106334 would tell me it's probably a 1961 , '71 or '81 if was your granddads . The other numbers on the back should give you the caliber and case # .  At 6 o'clock on the dial , numbers on the left would also give the caliber and numbers to the right would probably be the dial number  . Pics of the front and back would help to identify the watch . Once you know the caliber  you can search the bay for a NOS [new old stock] replacement mainspring [and barrel if it comes that way ] , or alternately a donor watch . I get a lot of donors from .... thewatchcollector  .... on the bay that are not expensive .  If you get donors then you can get your learning curve practice in with them before you tackle Granddads timepiece .

Good Luck and post some pics to get you started .

If its a faulty mainspring.. get a new one. Also since it has mostly sentimental, I would change out the spring to make sure that it can go the next 20 years! A lot of problems related to poor running are related to a weakened mainspring. 

 

Seiko handwinds are simple enough and a good place to start..but as mentioned above, getting a watch to practise on is sound advice.

Thanks to you all for all of the good advice!

I will certainly look into the caliber number to try to track down the NOS mainspring part.

Will post again if I have trouble locating the numbers.

Thanks again all p, really appreciate your help and advice.
