Movement Swap Question

[Aero_Dave]

Anyone know if a SW200 is a direct swap for an Eta 2836?

I'd like to know, including the hands as well.

I have some 'stuff' laying around and I plan on doing some work

over the holiday vacation time.

 

Thanks,

Dave...

Yes it is.

[Aero_Dave]

Yes it is.

Nice, do you know if the movements are the height as well?

Reason I'm asking is, I have a Ploprof V2 that the 2836-2 movement

has gone bad (Don't ask me how :-() and I know it has a unique movement

holding ring in it. The DWO sits on top of the existing day/date wheels and

the dial is only held in-place (aligned) by two dial feet But although the

feet do drop down onto the holder but they are Not locked-in by any levers

either like I've seen on other watches. So once you put the hands on, if you were

to lift the dial, it could possible pop-off the hands.

Once you set the movement in the case, the dial is held-on by the

pressure of it against the front of the case and the two movement holding tabs

on the back side.

So I believe the rep manufacturers just made a custom movement holder to be

able to use an standard Eta 2836-2 in the Ploprof.

 

I will be attempting to transplant the movement in-between the holidays.

I will be sure to take picture along the way and post later.

 

Thanks,

Dave...

Sellita's SW200 is directly swappable with the ETA2824.

Sellita's SW220 matches the ETA2836-2, (which is the 2824 with the added day function.)

mosyzlak is correct.

 

Although in most cases either will work as they both have the same diameter. But, since you have a unique case situation, you should probably go with the SW220 which is an exact replacement for the 2836-2, just to be sure.

Well I'm not sure why the rep dealers (whoever made mine, I bought my V2 from and m2m sale)

why they would use an ETA2836-2 when there is no day display, just your standard date window.

Here is the movement inside, I've already verified it:

 

 

 

Anyhow, I already have a new sw200 from a Seiko Monster that I'm

not using so that's what I'm going to try to use as the transplant / donor watch.

BTW, you can see the 3 outside screws / tabs holding everything into the case. The 2 screws just on either side of the

weight are the two that Barely hold the movement into the custom ring. The movement ring is about a good 1/8" thick

maybe slightly more. You can see the notch for the stem on the right. So because the ring is so thick, the dial feet do

not go far enough down for the factory ETA feet-levers to be used!

It'll probably work fine. The main reason that rep factories mainly use 2836-2 movements is they come standard with taller minute, hour, and second hand pins than what is standard in the 2824-2. And, it's easy to remove the day wheel and not use it.

Just a question. Whats a selita doing in a Seiko monster (not stock I'm sure!)

Same question? Seiko uses their own movements in their watches.

 

Dave another thing, I believe that the 2824 and the 2836 have different stem heights. I know in Rolex builds, they are not interchangeable, as the stem height causes problems with the movement if it isn't the correct one.

You are correct sir. I had a momentary lapse and forgot which watch I was going to use.

So the Real question is:

Will the Seiko 7S26C be a direct swap?
