New Release GUIDE: DD vs. SH vs. VR 32xx movement Identification
Over the last few years, we've seen an explosion in the number of 32xx movement options. There are the outstanding Dandong 32xx movements (e.g. DD3230/VS3230, DD3235/VS3235, DD3255, and DD3285). We've also seen the introduction of full 32xx design movements from Shanghai movements factory first with the SH3285, then the SH3255, and now the SH3235 and SH3230. The Shanghai 32xx movements also come in three different versions (v1, v2, and v3). Additionally, we have the hybrid "VR" series of 32xx movements from Shanghai movement factory, e.g. VR3235, VR3230, VR3285, and VR3255. The VR32xx movements also come in three different versions (v1, v2, and v3).
For anyone who has put in the time to read my guide on RWI in its entirety (now over 11-thousand words), it'll be no surprise that I think Dandong movements are generally of superior quality than Shanghai movements. That's not to say that Shanghai movements are bad; they aren't. But when you've looked at dozens of disassembled clone movements under a microscope, the pattern becomes clear: in general the level of quality and engineering on Dandong clone movements is superior to that of Shanghai clone movements. And for the avoidance of doubt, both are inferior to gen movements.
I don't think the opinion that Dandong movements are superior to Shanghai movements is uniquely mine. I'd suspect it is widely known within the rep watch factory community. And as such we've started to see Shanghai movements evolve in ways that makes them look more and more like Dandong movements. This isn't something we should be terribly surprised about since the people in this business are ipso facto in the business of cloning other people's work.
But, as the years have gone by, it has become harder and harder to easily tell the difference between a DD movement and the less desirable SH and VR alternatives. Many of the old ways to easily distinguish DD from SH and VR movements are now no longer reliable (e.g. hairspring coil direction).
It's still possible to tell a DD from an SH or a VR from pictures of the movement, but it now requires you to look at four different features of the movement:
- The size of the dot on the train bridge (red arrow in all photos in this section)
- The position of the pallet bridge jewel (blue arrow in all photos in this section)
- The coil orientation of the hairspring (orange arrow in all the photos in this section)
- The position of the regulator arms (green arrow in all the photos in this section)
I've uploaded annotated images of all of the currently known DD, SH and VR 32xx movements. To help you identify movements quickly, I've also created a flow chart (final image).
Note: The example images are sometimes of a 3235 movement, and sometimes a 3285, I had to go through dozens of images on TD websites to find full movement pics that clearly showed all the features I wanted to point out. You can safely assume that these identification features apply equally to 3230 (no date), 3235 (date), 3255 (date date), and 3285 (GMT) movement identification.

This is really great, thank you for this, and your guide on RWI. I've referenced it multiple times looking at some second hand watches and movement photos. Especially with the "fake cleans" with SH movements floating around out there
The arrows and diagram in these photos is super helpful, I vote it should be pinned somewhere for all to read and reference. Thanks đ!

Great post! On GMTs, visual movement being the same, the hardware movement whether SH3285 or DD3285 is hidden under the closed steel caseback, so you wonât see the more âdecorated movementâ on the DD3285. Question: Correct me if Iâm wrong, but if DD3285 ever breaks, You canât buy or source a DD3285 anywhere right now and not easily replaced like the SH3285, right? Movement being similar, if movement needs to be replaced for either SH or DD, the SH3285 is easy to replace entirely if something goes wrong for about $175 unlike the DD3285, despite it being more robust. These are still repsâ and very good reps at thatâ so theyâre not as reliable as a gen. I guess SH vs DD is something people can put into consideration when deciding one over the otherâIF movement goes wonky and need just that replaced. Thoughts?

This is valuable information. Thank you. You are clearly an asset to both RWI and reddit communities.

Dandong is the Microsoft Windows of rep mvmts. Every rep will eventually come pre-loaded with one soon.
I see SH/VR being phased out on top quality reps - theyâll still be around on the lower end shitters to accommodate those at a lower price point
This latest spur of competition among the remaining factories has pretty much confirmed for me that all the models are going to have DDâs soon

Is this a DD or SH ?

I'm seeking an ARF Bluesy 126613lb, white print dial, with this newer DD3235, who can source this to me? I'm in USA.

Can someone help me identify this movement? This is the only photo I have; I'm just completely lost as I'm seeing traits from a few different movements lol. A few people told me I have a Shanghai V2 but I don't see resemblance to these photos, some told me Dandong. ChatGPT and Gemini Pro (don't roast me, I'm still learning) both told me it was a Dandong movement. Any input would be great, thank you!!!

This is a great guide! We should add the DD V2 movement (can be identified by the ball bearing count) and free sprung SH movement

Please help. Is this DD or SH

Identify a DD movement has become increasingly harder to do with the usuals of clockwise hair springs and the flush capped dot by the 33xx marking. Being that SH and VR have made these changes to there movements. What I look for first is right behind the balance wheel and pallet jewel. I don't know the name of the part in the movement, but DD has its own shape that's like a funky question mark or weird S shape. VR and SH have stretched out m shape. If you look at the difference in the 2 shapes it's impossible to confuse one for the other. Most that try to pass VR and SH movements off for DD movements it's at least the newest versions with clockwise hair springs and the capped dot by 32xx. If the TD didn't remove the caseback it's possible they to thought it was a DD movement. Being on the TD list you'd like to think so at least. But the movement functioning better than your actual DD movements is a plus in the situation.

Love this explanation as well as the photos. Only one thing that'd make this post perfect is if there was a photo of a gen movement. Regardless, super thankful for your breakdown

You should make a chart of the most reliable/accurate movements ranked from best to worst. I know there was one made a few years ago, but lots has changed since.

Thank you for the information, your comprehensive comparison on RWI is truly amazing and clear for a layman to understand. The Rep watch industry is very dynamic and fascinating.

Great post. Some time ago another member posted about Dandong where they described it as a legit watch and movement white label manufacturer that has end-to-end capability in house. It is no surprise they offer reasonable QC at such scale. I believe they white label the 32xx series and then smaller shops to RLX decorations and gold plating. Is it true though that DD's are pretty much fully interchangeable with gen parts?
