Spare parts

[rossjackson01]

I'm still a novice. Is there a way to tell the manufacturer of a movement? Do all watch makers use standard movements and then put their own dials on them? If not. How can a new person to the repair system know how to order a part for a specific watch?

I need a crown and a winding stem for a Watches of Switzerland automatic mechanical day date gents watch.  Any help would be greatly appreciated.

Thank you.

Regards.

Ross.

Should be some small print letters and numbers on the bridge of the movement. Once you have that, just have to google it, or try sites like Esslinger.com that would handle parts like stems. Might even be able to find a non working movement on Ebay for a cheap price that has what you need.

If there are no letters or numbers on the bridges, look under the balance.  There is often letters/symbol showing the manufacturer, and model number e.g. Below is an ETA 2824-2, the symbol for ETA is just to the right of the number.

Do you have a pic of the movement ?

Thank you Craig2022, mikepilk for your prompt replies

I am due to receive the item Tuesday 1st Feb 2022. I will look as you suggest and will place photographs.

Hello Again. Watch has arrived. Not in as good repair as I had hoped. Therefore a long learning curve is ahead. I have attached the photographs and found the number as indicated. '2789'. The back cover states 'Incabloc' 97703.

Can anyone tell me what the movement is?

Any help on searching and ordering spare/replacement parts would be appreciated.

The stem appears to be missing.

Thank you in anticipation.

Regards

Ross

That's an ETA 2789. You can find additional information below.

[mikepilk]

If you look just to the right of the numbers, you will see ETA, the manufacturer. 

So you have an ETA 2789, a good movement.

A good reference site for movements is Ranfft : http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&ETA_2790

I've attached a parts sheet.

Due to space constraints, the manufacture identification is typically via hallmark. <= click the link, peruse the many, many images, lists, and charts.

Thank you so much folks. The pdf for parts is brilliant. 

How do I order the parts I need. Who do I contact, and how?

If you are in the UK, then Cousins is the biggest supplier. They sell to public as well as trade. They have a library of PDF files, which is where I got the pdf from.

For your movement,  enter 2789 in the search  https://www.cousinsuk.com/category/filter/eta-movement-parts

[rossjackson01]

Thank you. Hey! just did as advised, I can confirm that the movement is ETA 2789 - 1.

More questions

I am going to order the winding stem replacement and a crown.

As can be seen it needs a good clean. Being an amateur, if I strip and put the parts in an ultrasonic, would that suffice? Can't afford one of those whirling cleaners.

An ultrasonic is absolutely fine, it's what I use. Even hand cleaning is OK.

Do  a search for the thread on cleaning fluids. Cheapest is lighter fluid, or buy pure Naphtha from ebay. Then I use isopropanol (cheap enough from ebay) as a final rinse - naphtha leaves an oily residue .  I use just a little in glass beakers floating in water in the ultrasonic.

The attached PDF isn't the correct movement, but it's similar, and shows you the order to strip/rebuild and the oiling procedure.

What an absolute star.

I'm going to do a practice run on three movements to get some expertise. Then the fun will start. Probably 6 month or so before I get the level I want to be able to attempt such a job.

Ordering an ultrasonic.  I am also ordering the parts that I will keep for later.

Hi Ross  I have attached the tech sheet for the 2789, used in conjunction with the one Mikepilk sent  you should do alright, just in case you need parts the numbers are on the sheet                   cheers

Cleaning in an ultrasonic is great, and what a lot of us use. It's a midway point between naptha in a canning jar and a purpose built watch cleaning machine. You probably wouldn't want to just toss the movement in one though. You still want to disassemble everything, clean, then reassemble and lube. 

[rossjackson01]

Thank you all for your comments thus far. And for the connections and pdf's. I have been able to obtain the correct Winding stem and Crown. I amended the search as informed to ETA 2789-1. I did not realise the 2789 and 2789-1 stems were different. Just shows how good you lot are. 

Next purchase will be the ultrasonic and oils.

Getting there.

Good innit?
