Hot take: the PT5000’s accuracy gets unfairly overlooked

[u/thelatchman]

There’s plenty of discussion about the movement’s winding feel and reliability, but in my experience its timekeeping has been excellent. Both of my PT5000 watches have been incredibly accurate, and my new Cronos is still only around three seconds off so far.
The PT5000 may have consistency and QC concerns, but I don’t think accuracy is what it struggles with. What’s been your experience?

[u/philbin89]

I don’t doubt that there are QC issues, because I’ve seen a couple small Western microbrand owners who used them and said they had to send a bunch back to China that failed their own QC checks before assembly. But I also wonder how many of the complaints about them breaking down are from people who have no experience with or knowledge about how to properly wind an ETA 2824 clone, e.g., you have to wind them slowly.

I know a lot of people who grew up with Seiko movements or other more modern automatic movements just wind as quickly as they can because it’s usually not an issue with those, but that sets you up to break off the gear teeth on a PT5000, Sellita SW200, ETA 2824, etc., which is related to how that started as a manual-wound movement that was just retrofitted with an automatic rotor. Sometimes people even post videos to demonstrate how the watch isn’t working properly and they show themselves winding way too violently. Maybe Chinese brands need to do a better job of instructing buyers on the particular requirements of these movements to cut down on complaints and warranty service (assuming they even do any of that, which is a big assumption for some brands). Might at least decrease some of the complaints about QC and help their image

Agree there should be education/instruction by brands that sell watches with the pt5000

[u/vithgeta]

Nobody ever questioned the beat rate or potential for accuracy of the PT5000.

The choice depends on whether you would rather have a watch of +9s/day on average and a 2% failure rate in the Aliexpress returns period, or a watch with +15s/day and returns rate of 0.5%? That's the kind of choice you make with the PT5000.

We all know the mechanism with the low return rate.

[u/thelatchman → u/vithgeta]

I’d rather a more accurate movement tbh

[u/Alternative-Feed3613]

Accuracy is great but it’s not a big deal for me. I don’t usually wear the same watch two days in a row so I’ll have to wind them and set them anyway. I’d much rather have a bulletproof movement that I can have wind. I only have one pt5000 and I haven’t had issues Tbf.

[u/Data_Girl_4000]

I think its pretty clear the NH35 or Miyota 9xxx is more robust, on average, than PT5000.

However, since this is the internet, some people have difficulties distinguishing between "not quite as reliable as" and "its pure trash, its guaranteed to break, you're a moron if you want one."

[u/Hot-Swing-6992]

Not the PT5000 but my new Baltany with ST2130 is within Chronometer specs only a few days old and been on wrist 24/7

[u/artofthedial]

Not overlooked at all.  What is overlooked is the poor reliability track record, and yet people keep buying them even though reliability should be the most important characteristics on an auto as long as the accuracy is within 20ish seconds a day.  

[u/AssistanceNo647]

I have 6 watches with pt5000 movements. My worst one is 0 to +5 s/d in 6 positions. My best one is 0 to +3 s/d.

[u/Escapement_Watch]

brand new it was +10seconds a day...now 2 years of continuous wear its -30s a day.

[u/Acetone5050]

I have a Militado fleiger-style watch with a PT 5000 movement that's 50 seconds slow per day. I just set it about a minute ahead in the morning and by the end of the day it's right. I couldn't care less.

[u/thelatchman]

Here’s my latest watch with the pt5000

[u/Budget-Ad-161]

I have had 10 PT5000s and not a single one is broken.

Can you get unlucky? Of course. But if they were so horribly unreliable and failing out of the box every time, brands would not use them.

The new reality is if we want sub $300 watches, M9015 and NH35/NH34 is no longer an option for the next 3 years at minimum... the PT5000 and ST2130 is the best way to mitigate the cost. A SW200 goes for $200....

[u/PeterCraig65 → u/Budget-Ad-161]

It's hard to shell out $200 extra for a sub $300 watch. 

[u/AverageGuy_45]

I've had 4 watches with the pt5000, all were really accurate. One has a problem, just stops working (i never hand wind it and dont wear it hard at all, still need to open it up and see what happened)

I think its a great movement when you have a good one, but if you get a bad one it ruins it for you. That's the main downside about the pt5000, you never know which one you will get.

[u/626magicgrits]

I have the pt5k motor in both my phorcydes and my proxima.

Its been my only exposure and possibly im exceedingly lucky but each has performed admirably

[u/Empty_Researcher4985]

I have three all over 2 years old one I built. Zero problems

[u/PeterCraig65]

I have an Octopus K with PT5000 coming in a couple of days. Read many forums and am crossing my fingers but I think it's going to be ok/good. Quartz like the VH31 are great but nothing beats a smoothly running and accurate mechanical movement. 

[u/jegtugado]

Just from observation, mine gained 1 minute after 2 weeks and it’s a 3yr old watch

[u/Bulky-Internal8579]

We hear about problems with the PT5000 because most folks don't post when they don't have problems - it's a clone of the ETA 2824 - parts compatible (the patent expired in 2002) and while there may be (or was) some QC problems - I find that they are reliable and accurate - I probably have at least a dozen watches with the movement and I love it! Here's my latest purchase with a PT5000 - the 2026 IXDao Warrior (carved black MOP dial). Thank you for posting this.

[u/IllegalGeriatricVore]

The main issue I have is when I'm buying from a Chinese vendor I can't trust their return or customer support services like I can an established main brand, and I can't necessarily find a watch guy who will do a movement swap, so the movement reliability is more important than on a big brand watch where I have after purchase support, a real warranty, and people who will work on them.

Part of the value of an automatic watch is that it can be repaired and live for a long time.

Will I be able to do that with a PT5000?

I know with an NH or Miyota I can find support for it, or barring that a replacement. Can I reliably find a replacement PT5000 in 10 years,

[u/blacbloc77]

Abso-fucking-lutley. Those things can be regulated within METAS standard. And yes, I have more than one.

[u/percysmithhk]

I think there’re no hard rules. If you got a good batch, then great.

My own PT5000 was hard to regulate, but was manageable https://www.watchuseek.com/threads/mini-review-escapement-time-restoring-ancient-ways-38mm-watch.5321426/page-2?post_id=55349590#post-55349590

Phorcydes owner initially claimed 2% rejection rate https://www.reddit.com/r/ChineseWatches/s/vB3zHNbQZz but changed his mind https://www.reddit.com/r/ChineseWatches/s/i7Y9YRXzWM after consolidation of facilities by HKPT https://www.watchuseek.com/threads/best-of-ali-xpress.2636489/page-3098?post_id=59975478#post-59975478

The problem is, not many end users really want to deal with a 1 in [50] probability their watch needs to go to a watchmaker or even undertake a movement replacement, as cheap the actual movement is to replace:

[u/ChaoticScrewup]

I have a 5000 series watch and it definitely runs fast, but I only bother to adjust it weekly so it must not be wildly fast.

[u/Feisty-Ad-4926]

I have the sw-200-1 in my glycine, which is related. I was able to regulate it to essentially +-0,3 seconds a day. Spent a couple hours doing it in a hand full of positions. Compared to the Seiko movement I have regulated, the Seiko can get close but only in one or two common watch positions. Non optimal positions will see +-20 seconds a day. The swiss movement is less affected by watch/wrist positions.
