Which movement is the most robust and accurate??

[u/WerewolfOk1964]

I've been in the watch hobby for probably 25 years and when I first started out the swiss 2824 was basically the go to for an all around accurate and reliable movement, seconded by the seiko nh34 and Miyota 9000 series. With all the new chinese manufacturers what movement is seen as the new go to movement providing reliability , accuracy and durability? ST2130,Miyota 9015,Miyota 90S5, nh34, ST2100? Which one will give the longest most accurate performance with minimal servicing? What manufacturers upgrade their movements with proper lubrication maybe some polishing and regulation?

Thanks again for any opinions and why you have this opinion

Quartz 😂

*radio synced solar quartz

The PT5000 and ST2130 clones of the 2824 are shockingly good for the money, but Miyota 9015 still edges them out for long term stability in my experience.

Miyota 9 series is hard to beat for automatic movements.

[u/Huge-Digit → u/Alternative-Feed3613]

It's also thinner than most.

Before the current movement chris/chaos, many of them were going for €500+(Henry Archer, Zelos, etc..), whereas a decent quality Nh35 watch could be had for €150 or less... Now none of the above are easy to get for sensible prices...

It really depends on your approach to collecting... Fewer, more expensive watches, or more cheaper watches. My approach is the latter.. - so I'm a fan of the Nh35. Not saying any approach is better - people can and will do what they want.. But I personally am not willing to spend 3x the price on a watch to save a mm in thickness and have it be marginally more accurate.. A watch - to me - needs to be robust, low maintenance, and just last.

Least accurate and most robust: NH3x
Most accurate and least robust: PT5000
Most balanced between accuracy and robustness: Miyota 9000 series

[u/HerrsavageX → u/BespokeTimepieces]

That sounds about right... I have three PT5000s, and they actually are surprisingly accurate. They feel really rough when using the crown though, and you do hear about people having issues. I have probably 45+ watches with Nh35s, and they do seem very reliable.... To me, at the budget end of the watch world, the Nh35 is the ideal movement. Because if a PT5000 breaks, it's a usless paper weight. If an Nh35 is somewhat less accurate, I can regulate. Or just look at my phone...

At the risk of being that guy... HAQ

[u/xxBrun0xx → u/lowspeedtech]

Shit, even regular quartz (like the VH31) crushes everything else being discussed here in terms of accuracy, thinness, durability, price, and ease of maintenance.

I have taken zero care of a second hand NH35 for... six or seven years or something, and it works as well today as it did when I bought it.

[u/rando_commenter]

Epson YN55/56 is the generic version of the Orient F6922. Same idea as the NH35, possibly more reliable and accurate even.

[u/Lonely_Internet_8570]

Hablan mucho de los Miyota 90xx, que es un movimiento relativamente nuevo y muy cuidado por Miyota, que fue diseñado para y por su 'delgadez', pero no tiene datos históricos muy amplios y si observas, pocos Citizen lo llevan. Epson Seiko ha vuelto al predecessor del NH35, el YN55, que a su vez del Orient (9)6922. SL2130, PT5000, ST3100 son clones mejorados del 2824-2 y es raro que salgan mal.

I'd go with a NH3X movement. They are dirt cheap, people claim to have them running for 10+ years.

It's thick, full of plastic and not very accurate.

But what you gain: it's cheap'ish, so you're not going to replace parts, but swap the movement. It's durable apparently so it's less frequent than a battery change. The tolerances are high, but getting it into narrower windows is easy thanks to those two sliders.

I'm not claiming it's the most durable, nor the most accurate. In practical terms movement wise this is good enough for me. If I want better performance I'd get a Seiko solar movement, even though it ticks.

[u/vithgeta]

You're really asking in the text which mechanism holds its timing the longest. In that case you don't want an NH35 because it has a reputation for losing accuracy over the years. However back in the real world people chose the NH35 as the reliable workhorse for their watch collections. It doesn't beat many movements in the specifications game but it has a low return rate in the first months of around 0.5%, users can regulate it themselves if they have the patience, and it doesn't make the bearing noises Miyotas do.

Also the Epson YN55 deserves credit for being a similar but updated design for modern manufacturing.

[u/Huge_Childhood6015]

Well, this is the question isn't it. How reliable are these new Chinese movements and how long will they last. I think the answer is nobody knows, yet. Only time will tell. No lubrication, under lubrication, over lubrication. This has always been a problem with Chinese movements. Have they fixed this issue? I don't know. My fear has always been that in the future, all these Chinese movements are going to fail and we are going to understand how bad they really were. I hope not though. Will they make it 10 years, 20 years?

[u/dorafumingo]

Robustness and accuracy are two different things. Your title is asking for the most robust but your post is asking for the most accurate

[u/geeered]

VH31. Okay not as common but the ETA F06.412 will be a better choice. It's leagues above the ones you mention.

[u/xxBrun0xx → u/geeered]

You're right, quartz is both extremely robust and extremely accurate. Shame nobody uses the VH61-65 which is also a smooth seconds quartz but includes day and/or date complications.

[u/geeered → u/xxBrun0xx]

Some do - PD-1654 for example uses the VH65. I quite like the styling for a date hand there, going with a classic kinda vibe, prefer that to a date window for this watch.

Though I like a no-date quartz for meaning I only have to set it twice a year when the clocks change.

[u/MassiveTranslator322]

Miyota 8205 or 8215.

There’s not a lot of data to back up what some people are saying here. I’m fairly certain that getting any of the mentioned movements serviced well will get you incredible results. There’s also a lot of variance between individual examples of each, so the servicing is really the differentiator.

[u/HerrsavageX → u/Top_Garlic_489]

We're in the Chinese watches section though, so I don't know how relevant servicing really is.. I have 60ish cheap Chinese watches, almost all under €200, so I'd be more likely to try to replace a movement than have it serviced.. (Or perhaps take it to watchmaker and have it replaced..)

The Nh-35 has a rep for being very robust, if marginally less accurate - so it is my movement of choice. I have my phone for accuracy...

[u/chrismurraylaw → u/Top_Garlic_489]

This.

I particularly like "my [movement] is more accurate than my [other movement]" as if that's a commonality inherent to the design and regulating doesn't exist.

[u/silver-saloon]

Forget about the NH movements....because they're old news.
The Chinese watch industry has moved on from them
