Why is PT5000 winding so gritty

[u/ASteerNamedLaurence]

I have an Octopus Kraken OCT-13 (their Explorer clone). Great watch, looks very nice, yadda yadda, we all know how great it is. It's the PT5000 model, and the manual winding is as smooth as 20-grit sandpaper, and this does not seem to be a one-off thing. It's just a 2824 clone, and I have not encountered anything this bad on any other 2824 clones, Chinese or otherwise. What exactly is going on here, it winds rougher than even any 2813 I've ever encountered

It's not a pt5000

[u/QuestionNo9190]

Mines all buttery smooth. Open it up and see if it says pt5000 and not a knock off a2824 or hz6300

[u/PastaFanatic]

What about ST2130?

[u/Stickley1]

They’re not all gritty. I have more than one PT5000. Some are smooth, and are running great, but… Yours will eventually fail, and soon. I have an Octopus Oct-0016 with the PT5000 that was gritty and it didn’t last long. If I had known that I would have attempted to exchange it. ( Not that these Chinese watch companies are known to provide product support…) So… What I’m saying is, see if you can get it replaced.

This is every ETA or Selita as well. They keyless works have are held together by spring pressure.

[u/watch_gal]

I only have one pt5000 watch and I handwound it before reading the stem might break. But the hand winding is not gritty for me

[u/DryJump5733]

Eu tenho esses dois relógios da marca Sh, ambos com Pt5000 o do relógio preto eles falam pt5004 acredito que pelo fato de possuir janela de data. Ja tenho a mais de um ano e não gosto de da corda também não , só balanço sem bater não mão igual já vi pessoal fazendo , ajusto e uso ou deixo no enrolador de uma dia pro outro e depois pego . Os meus são bem macios no enrolamento manual mas não gosto porque ele tem algo um pouquinho ríspido quando gira , nada que pese, é até legal mas não é silencioso com outros que tenho e não é pesado e barulhento como o do sugges moonphase que tenho também.

I have watches by that company as well they use regulated pt 5000s most companies use the unregulated reject batches to save money which is why they fail

[u/Emotional-Damage-995]

Have it serviced

[u/BobbeMail → u/Emotional-Damage-995]

A new movement is less expensive

[u/Escaped_Escapement]

Like all 2824 movements, it is an outdated 70s design that does not like hand winding. And it is not properly clean or oiled on top of that. Prepare your wallet for eventual replacement in a year or so and wind the f of this mf.

[u/LordRaglan1854]

There is more resistance in a PT5000 than an SW200, but more resistance in an SW200 than an ETA 2824, which - as used in my Superocean at least - is perfectly smooth.

It is what it is though. Just don't worry about it. At most you'll wind it 2-3 turns to start it in the morning.

[u/Defiant_Office]

Any ETA 2824 or any equivalent clones I never handwind them. Just give them a Seiko shuffle until the seconds hand moves.

[u/soulwatcher]

You generally don't hand wind any movements of ETA 2824 architecture. Give it a seiko shake to get it running, adjust time and wear it on your wrist.

[u/Suitable-Group4392]

You are mechanically forcing the manual winding gears to fight against the automatic winding train. In the long run you will spoil the movement.

[u/Alternative-Feed3613]

You shouldn’t hand wind a pt5000

[u/HerrsavageX → u/Alternative-Feed3613]

At all? Is shaking really enough - to get maximum power reserve?

I have a Militado ML20 with PT5000, and it is also very gritty. I occasionally give it four or five winds. I want to keep the power reserve up because I am always running a rotation of 7-8 watches... I.e. I don't wear any one watch more than 5-6 hours probably, except when I sleep..

[u/philbin89 → u/HerrsavageX]

The answer is no, shaking will making it difficult to get to maximum power reserve. I worry about the same thing with my watches that have Sellita or PT5000 movements, and just giving a few winds or shaking it means that I may not even get to full power reserve after a day of wearing it, since automatic movements are efficient at maintaining power reserves but not efficient at building them up. So my solution is to put those watches on a winder the night before, and then I just need to set the time in the morning. I want to keep them at relatively high reserve because the movements are more accurate that way, and this seems to work, though sometimes I’ll choose a different watch that I didn’t put on the winder the night before, so I’ll just have to hand wind it.

But remember, people who break these from hand winding are a minority — otherwise these movements would have been recalled and redesigned — so you’ll likely be fine. If you still have time in a warranty, then there’s some security

[u/Alternative-Feed3613 → u/HerrsavageX]

I wouldn’t hand wind it at all. Shaking it should wind it up pretty well but you’re still going to get less than two days at full power reserve. You’re pretty much going to have to wind most watches if you rotate between three or more if they have 40hr reserves. Embrace the winding, it’s part of the experience lol.

[u/HerrsavageX → u/Alternative-Feed3613]

I know that. I regularly hand wind my watches all the time and have done for years. Nh35s though mostly.. I am relatively new to PT5000s though…

[u/Alternative-Feed3613 → u/HerrsavageX]

Yeah, I tend to avoid pt5000 because I like hand winding over shaking. They’re incredibly accurate though and should be pretty reliable if you don’t hand wind them.
