BP sub-C movement teardown pictorial (pic heavy)

[discostu 0]

There has been some discussing over the movement found in the BP sub which Josh refers to as a "new breed 2813".

Looking at the pictures posted it displays a lot of similarities with the 2824 clones.

Mine was delivered today and I just couldn't resist tearing it apart to see what it really is (a cleaning & lube job is usually a good idea anyway).

 

It seems that the going train and auto-module is very similar, however the keyless and date module is not the same.

Anyway, i snapped some pictures if anyone is interested.

I only had my phone cam available so they're not that good, but here they are nonetheless.

Awesome thanks for sharing! I'm trying to built up the nerve to try this myself!

Some of the best phone pictures I have seen taken! Nice job. How smooth a sweep does this movement produce? I know it's high beat 21J 28.8k right?

Great teardown, hope it goes back together ok im a bit of a shite bag so would never do this myself good on you.

I'd say the sweep is quite smooth, much better than my DG4813 which is also 28,8k but doesn't have "direct drive" seconds.

I can post a video when it's back together (hopefully).

Thank you very much for this teardown mate !

 

Now I think it is an attempt to fool us with of use "ETA" movement

Fun thread. Thanks so much for posting this. Any intention of posting a detailed walkthrough of the cleaning/oiling procedure?

Nice Job!

 

I was wondering about these.

Great stuff, I'm educating myself for some future tinkering so these types of posts are gold.

 

thanks for taking the time.

Thanks for the tear down, it certainly answers some unanswered questions many of us had on this new breed movement.

 

Thats the first time I have seen a date wheel like that too.

Here's a short video of the sweep for those interested.

That date wheel overlay is neat looking.

You're nuts... I'd never that it apart that much. The dial is as far as i'd go

Great thread. I have one of those coming. Do you think I could sub the movement with an eta (would it fit)? Is it even worth it to do that?
