Hi guys,

I recently got a ST36 from aliexp for a project, when I got it I noticed the cannon pinion was shorter than I was expecting. So I pulled out my other ST36 and compared them.

To my mind the short one is not fit for purpose, before I go and shoot my mouth off and leave a bad review on the sellers page. I thought it might be wise to ask you guys for advice / thoughts. I have attached pics of my old one and new for comparison.

yep that won't work, you may get it to work if you transfer the hour wheel but I suspect the dial may be too thick.

You can transfer the cannon pinion and hour wheel from the old movement, unless they're no good.

Yea I already transferred the canon pinion from the old movement and am wearing the watch today . I was more checking my facts before I wrote a bad review on the site.

Do you think perhaps the seller would just give you another hour wheel and cannon pinion? They may be able to do that if they are purchasing them directly from the manufacturer.

I'm just wondering how it's possible .. they must also manufacture a variant with a short cannon pinion and the seller send the wrong one maybe ?

As mentioned above, nothing is ever sure buying when buying Chinese. It's not just that the seller only cares about is to formally fulfill the order, also in most cases he genuinely doesn't know what is what and has no help from the distributor.

I just recently bought a couple of these Chinese ST3620 movements. They came very well packaged and though they were not advertised as coming with hands they have the minute hand installed. This obviously precludes the defect that you've encountered from making it out the door.

I haven't dropped them on the timegrapher yet to check out their numbers.

Yes the cheapest ever hands are Installed probably for rudimentary timekeeing checks.

Most likely these will be good or very good, the issues maycome later when the lack of proper lubrication becomes evident, or god forbid one will need any spare part beside he stem.

I bought my ST36 movements from manbuwatch but perhaps it would've been easier if bought directly from cousins instead since the price difference was neglible after the swedish postal service charged me for VAT and took 50 SEK (~5€) for the trouble. 

They came with very cheap small seconds and minutes hands (basically useless) very well packaged and no problems. The movements keeps time pretty well after service and lubrication and if you can adjust the etachron properly it gets even better in different positions.

Since I bought them for practice, I have lost some parts (end stones and shock springs) and also broke a stem when I dropped a movement. It is impossible to get any spare parts and though they are clones of UNITAS movements, those parts don't fit.

But that cannon pinion looks to small for that hour wheel. Sorry.

Hi. Just wanna know how much you take to buy that movement.

Basically, these movement only cost you about 100~200RMB which is around 10~20€, so it's possible to have this type of shit. And buyers in China also knows the risk of it. No so sure where do you get this one, so if this happened inside China, the seller normally sent you another hour wheel and canon pinion.

      Not a family member, and yes, it no way near as good, as some information got lost from original site and some information got incorrectly copied. The original site is available as iOS app here: https://apps.apple.com/fi/app/ranfft-watch-movements-archive/id6502008939

      Seitz Tool - Help determine if Seitz or not

      By Hawaiikook808 · Posted

      Outstanding, Marc! Your information is really helpful and clears this up, especially given that yours were purchased as sets. Thanks, man. So, it appears I jumped the gun on this one, but I am relieved. I will say, though, that all of my reamers and concave pushers are number-stamped and appear to be of better quality.  Also, the bayonets on my pushers are actually the same color as the steel.  The next thing to do is restore the heads of these pushers with some polishing paper.  Alex at the Watch Repair channel has a nice little video on this.   I appreciate your help!

      Just installed it on my iPhone (my only iOS device) and it appears to be intact and functional. I may have to go out and buy myself an ipad just for this app.

      Seitz Tool - Help determine if Seitz or not

      By Marc · Posted

      I have two Seitz sets, one ancient (with the 3mm anvils) and one just old (with 4mm anvils) plus a collection of spare pushers of assorted vintage. Not one of them is marked with it's size. Something which I have found very irritating when I have been using the tool and not returning pushers to their correct place in the tray every time as it means that I have to get the calipers out and measure them. These were bought as sets and collectively I have over 100 pushers so it would seem highly unlikely (if not inconceivable) that they are all cheap knock offs, especially as they are old enough to pre-date the prevalence of the Chinese knock off industry (at least as applied to watch making tools). I therefore believe them to be original Seitz parts. And there is no numbering. The shape of the bottom of the pump pushers is the same as your photo. The only thing that may not be the same is that the slotted insert (looks like a screw but is in fact a bayonet) should be brass. Yours looks the same colour as the steel but that could just be the lighting.
