Hiii my friends

This time we shot the APS Dandong 3120 clone movement, which has been in the market for nearly a year, and the overall repairing rate is not too high. We disassembled their genuine 15400 movement shamelessly. hope I won’t get beat up.

The genuine 3120 has been halted production, and the new one in the 15500 is 4302 movement. I asked my friends around and no one has it, so I was thinking about whether to take out my own money to buy one. :unsure:

3120 movement can fit in many models, such as 15703, 15710, 15707 and other common three hands + date models.

3120 movement was specially made for JF, but after that APSF took it over along with some accessories of JF and AP 3126 and so on. This would be another story I should just stop here.

The overall of this AP movement is not bad, some details are not so perfect, and the polishing can be better.

There are detailed disassemble pictures below which I was really enjoying. Most factories are unwilling to develop new movements now. Because people don’t really like replicas and some of them will report this. Noob is a typical example.

Without further ado, let’s take a look of it.




And the video is here:


Hope you enjoy it!

killing it with these threads!

Definitely close, 85-90% identical, but not a complete clone movement like the 4130. Based on what I am seeing, gen balance wheel and bridge would not work with clone main plate.

Outstanding photographic review of the 3120 caliber. It's great to see the differences side by side. Thank you for the effort that goes into these projects. These are hugely valuable!

wow honestly why should you buy gen anymore with replicas like this 😅
My friend, many paople don't know what they are buying, we just provide them a way to know our products, telling people we are serious about watch. We spent so much effort on this kind of comparison post, also many menbers here really want to see this, that's why.

I do recommend this 3120, including 4320, they are the only two that can count super clone AP movement to me.

Wow! Another great and detailed teardown of a new movement. Very nice work and thank you so much for doing so, not many dealers go to these lengths to inform members! Thank you CTime!

Section mods: Hope you don't mind, I've pinned this post.

Hi CTime, thanks for your great efforts on this 3120.

I am sure I am asking too much.......nevertheless, would you consider doing a similar teardown on the AP4302 ?
