DGxxxx Movement I.D

[SL1234]

I accidently snapped the stem whilst changing the crown. I now need to find a replacement stem that will fit. i assumed the movement was a DG2813. So i tried a couple of other stems from some other DG2813's i have , but they don't fit.

Comparing mine with the chinese movements on ofrei.com here http://www.ofrei.com/page1119.html

The movement looks to be a DG3806B

My watch is a simple hour,minute and small seconds hand at 6 o'clock arrangement. So looks like a match above, however when comparing mine with other pictures of the DG3806B from the web, my drive train wheel is exposed, and is not on those pictures. So now im not so sure.

Can anyone identify this movement ?

Another question - If i measure the movements thickness, do i include the rotor and screw ? or do i remove it ?

Any help is appreciated. Thanks

The movement looks similar but not the same - tab screw holes are not in the same place for example.

However Raffles time sells a stem that looks to be the same as yours - for the price it's worth a gamble....

Yes that looks very close indeed. Will order it and see. i contacted the seller and it is currently out of stock until next month...so i'll have to wait.

Thanks

Ken's a nice guy, but he's pretty chaotic with stock contol (and communication) - same item at cousinsuk ( cheaper & quicker):

https://www.cousinsuk.com/product/chinese-movement-stems?code=DG2803401

Part No: CH3804B401 - towards the bottom of the page.

You'll need to register (if you're not already) before purchasing.

Thanks again. ordered!! cheers

Update: It's not a match im afraid. The squared section is a little shorter and the bulbous part is abit longer on the new stem. I can adjust the hands just barely in one direction. But the other direction it just slips and spins. Winding the spring is a no go. Bummer. I will try and return it and order a DG3806B stem.

Put up a GOOD quality photo of the broken stem, I'll have a look in my Big Box Of Broken Movements And Their Assorted Bits see if I've got something that will fit.

I found another watch in my collection that has a (i think) 3804(B) movement. It has the same top plate and exposed drive train wheel as the watch in the OP. But it is a Date at 3, GMT arrangment.

This watch
http://puretime01.com/explorer-ii-4...-edition-white-dial-on-ss-bracelet-a23j.html#

and the stem from that looks to be an exact match. I plan to donate the stem over. Except the thread is too short , so i am currently waiting for some stem extenders from China.

So maybe the stems are different for whatever reason on some movements thats why it is labeled 'B' maybe? or cousins sent me the wrong stem ?

or i have some kind of franken movement ?

I could try the stem now, but i would have to remove the movement above in the OP from the case. Im not sure how it is held in. The only visible screws look to be holding the top plate on. I think it might be wedged in the case. So i'll leave that for now.

Will take a better picture tomorrow in the day light.

Thanks

There are dozens of movement manufacturers in China all producing variations of the same movements, but parts are rarely interchangable - 2 factories making a GMT movement will probably not use the same stem design.
The movement in the watch in the OP seems to be held in by the large ring - pressure fit - a sharp tap on the table might dislodge it - might also break it
Why do you need to remove the movement to try the other stem?

The stem i found won't reach movement because of the sticky out rod on the case. I have tried to unscrew and pull the rod out but i cannot get a good grip without it deforming. I am not even sure it even comes out.

I even tried to take the crown off the stem i found and it still wont reach. I fear if i shove the stem in still, i wont be to get it back out or even be able to turn it.

I think it was cut too short at the factory.

The "sticky out rod on the case" is the tube. So the stem/crown from the GMT might fit but is too short for the case on the other watch?

If you put up a decent quality picture of you broken stem I'll have a look at what I've got - I know I've 5 or 6 assorted stems, all from chinese movements - one might fit.

After another inspection of the stem i found, the crown had an extra piece protruding that wouldn't fit into the tube. So i just went to do the swap to a flat crown and just touched it with my pliers and it frigging snapped on me at the start of thread next to the bulbous part. Sh*t. I think the stem extender will be too close to the keyless to work or there might not be enough thread to grab. Back to square one lol

Here's the original broken stem

Well I knew that stem looked familiar,its because I have exactly the same one - snapped off at the base leaving about a half millimeter stub on the threaded side !
I tried everywhere for a replacement - never found one. Tried repairing it - glueing/ soldering a stem extender on, nothing worked. After the third nervous breakdown I gave up. If I recal correctly the watch came from Narikka, so the movement wasn't even chinese but probably from Thailand....

The good news for you is that as long as you have enough length on the snapped GMT stem to get an extender on it shouldn't affect the working of the keyless - this part of the stem doesn't go inside the movement so you should be OK.

 

[SL1234]

OK gotcha. Why cant the stems all be universal ? what a pain.

I have a semi dismantled 2813 movement and stem in my spares box. Would it be possible do you know to transfer the keyless work parts (the winding pinion and castle wheel) from the 2813 over to the watch in the OP ? or is there another piece of the jigsaw i would be missing ? if it can be done. Do i only have to remove the dial side of the movement ?

LOL Great minds think alike - I considered this option too. Whilst in theory it's possible i think in reality it's probably not going to work, too many variables. But you can always try.... :happy-1:

To get at the keyless works you need to remove the dial, the date wheel, if present and the retaining plate. I suggest you look at some tutorials before trying, it's not too difficult if you know what you're doing.

The other option is buy a new seconds at six movement. I found 4 on cousins, all are 26mm diameter. If you remove your movement, take off the hands and dial you can compare it to the movements on cousinsuk. You'll need a digital caliper to measure the diameter of your movement, the height, and the distance of the seconds hand from the centre of the movement so that the new movement will fit case / dial etc.

Seconds at 6 movements:
DG1800
DG6806
TY2705
TY2706
For the last 2, hand sizes are not given - wtf?

Just looking for a strap for my latest - Blancpain Fifty Fathoms Mil Spec :whistling: on Ebay and saw this : http://www.ebay.com/itm/Watch-mecha...4D-GMT-/121960529943?var=&hash=item62028c9ed7 RK 4D with the white plastic crown.

Looks very close to what you want - but not cheap if it's wrong. Maybe send him the photo from above (next to ruler) and ask him to check if the same size. (barrel at base of threaded part is longer but shouldn't make any difference.)

 

[SL1234]

If the extenders don't work out. I will consider that ebay stem. I have everything i need to do the keyless swap so it's worth a try. Im very close to the buy button on Cousins too.

Do you reckon any of these will fit ? worth a gamble ? im thinking if they could be modified to fit without too much heartache if i mess up
Assortment of 144 winding stems

Thanks for the help.

Considering the price it's worth a gamble - I can see a few in the pile wich seem to have the same proportions as your looking for - but he does state that the selection of stems will be random... But worth a punt never the less.

 

[rsh]

is this it?

 

[SL1234]

rsh thats looks like a very close match. The squared section is little bit shorter so not sure it would work. I ended up buying those 114 ebay stems. Just waiting on some stem extenders to try them out.

If none of those work. i would like to buy yours above. How much do you want for it ? (i dont need the crown)
