Help! Troubles swaping an A2824 to Gen ETA 2824-2 in BP Explorer 214270

[SkyMaster337]

Brought my BP Explorer 214270 to my watchsmith for what I thought it was a straight swap.

I also ask him initially to “delete” the date setting position on the crown by ordering a 2 position set lever but he recommended me not to remove the date disc as I wont be able to see it anyways.

When I went to pick it up he said the only problem is the crown beeing difficult to screw in. Apparently the steam sits too high on the case slightly bending the steam and preventing the crown to screw in smoothly/correctly.

Obviously that is a no go for me.

Any idea what can be the problem?, any imput would be greatly appreciated as my seccond option is putting back the shitty chinese clon inside after service.

Could it be that mounting it with the date disc is eating some space between dial and movement making the movement to sit high into the watch case?

what do u think could have gone wrong?

Thanks

Are you sure the the original movement was a A2824 and not A2836?
Or perhaps he neglected to use the dial spacer

@Hor-Fan hits the nail in the head.

I had this and it was because the original movement was not an 2824 but a 2836.

I agree that the other movement may have been a 2836 which has a different stem height than 2824.
As for the date, I normally remove the date bits but it doesn't hurt to leave them in. A 2-function setting lever jumper is a nice replacement for the 3-function version, but you have to order one or mod the existing one. This will get rid of the ghost position when you pull out the crown.

Just checking my old email with Toro Bravo.

He quoted me;
- 316L with 2036 movement for 298 $
-904L with 2824 movement for 358 $
Finally I purchased the 904L with 2824 movement.

After payment, I ask him for checking again the movement and he confirmed It was the 2824 again.

June 2019 Order number 5963. Could him had sent me the cheapest one beeing a trusted dealer?

And if that is the issue, beeing a 2836 instead a 2824, is there any easy way to adapt a 2824 or is better to service and install the original chs movement?

 

[Raddave]

do you have a pic of the original movement dial side ? (without the dial )

 

[SkyMaster337]

Can get it tomorrow. I will post it.

A watchmaker should know better than to install a 2824 in place of a 2836, the stem heights are not compatible.

You can tell from the backside of the movement which your original movement is. There is a hole for a calendar part visible in the 2836 from inside the dial foot cutout on the non-stem side. You might have to put a light up to the cutout to see it.

Both gold movements are 2836s, both silver are 2824s.

If you do have a 2836, I think your best option is buy a 2836 replacement and start over. You can sell your gen 2824 or keep it for future use.

This is the part you need to get rid of the date stem position.

I always remove all the calendar parts too for a non-date watch. It gets annoying to hear the day and/or date flip when setting the time or at some random time of the day when they auto flip. Someone who won't remove parts on request isn't likely going to set your hands at phantom 12 o'clock. The rep factories don't.

 

[SkyMaster337]

Thanks very much for the help!

@Raddave here are the pics. (My watchsmith thinks is a A2824)



What do you guys think? Defineately hasen´t got the holes @KJ2020 mentioned.

@KJ2020 thanks for the part reference, I will definitely get it. Does the original steam work with it?

 

[Raddave]

that is a 2824

 

[Hor-Fan]

Hmmm..Puzzling. Are the pinion heights the same on the two movements? Was the original movement installed without a dial spacer since the date parts are removed?

Yes the original stem works. Since your rep is a 2824 (yay Toro) and the gen sits higher, the obvious culprit is the dial spacer, as @Hor-Fan mentioned. There may be a dial spacer height difference between the two 2824's. I would investigate that. If the rep spacer is taller than the gen spacer, you'll have to use the rep spacer. However, sometimes then the hands pinions on the gen (typically H2 height) won't extend far enough above the dial to fit the hands. If this is the case, H4 pinions are needed. But that would imply the rep already has H4 pinions since the hands fit previously. If so you can use the rep pinions or if you feel the need you can buy new gen H4 pinions.

@Hor-Fan Dunno, my impression today when I went to take the photos of the movement is that he did strictly and literally a movement swap without paying much attention to anything but all out, movmt swap, all in. Only after I complain he said he will look into it and I shouldn't worry.

@KJ2020 the ETA I bought was barely the movement without any dial spacer, so dont think he swap them over.

Now that I got all your tips and we check it was not an A2836 I am sure It can be easily fixed. I will let you know once its done what was the actual problem and how he fixed it.

 

[KJ2020]

Keep your goal in sight!

I knew this rep needed a gen movement right away. It's a keeper for sure.

 

[SkyMaster337]

Just pick it up today after a seccond try.

He said the dial spacer was too thick and milled it down 0.01-0.02mil.

Crown still not straight and threads starting to suffer on the crown tube as crown is not screwing in correctly.

Movement still sitting too high on the case and dont,t know why.

Don,t know if I should give up as I dont want more disambling and ensambling due to risk of getting scratches on dial / hands...

 

[WatchSmith.US]

If your stem is not centered or at an angle in the crown tube per your photo, then you run the risk of damaging the mainplate as well as other parts. It's hard to have a solution going by these photos.

 

[Raddave]

looks like the dial spacer is still too thick to me ?

 

[Hor-Fan]

Looking at the original movement, I see no dial spacer. I think your watch maker needs to install the new movement in the same configuration as the original clone - calendar parts removed, no spacer.

P.s. the movement is sitting too low.

 

[KJ2020]

Are you sure your gen movement isn't a 2836?

If not, trim the dial spacer more or just don't use it.
