Miyota 9039 vs Sellita SW-200

Given a choice between the two, all else being equal, I'd go with the Miyota. A $400 price difference would make that a lot easier.

There are other factors in choosing a watch besides movement and price, though. Make sure you consider those as well. The movement is a pretty minor factor when it comes to owning a watch you enjoy and wanting to keep it long term.

I was at a watch show last weekend that featured mostly microbrands and included Christopher Ward. Since I've had the helicoptering rotor issue with two new/old stock watches I purchased, I specifically avoided any watches with the SW200 movement and actually bought a Mark Time watch with the 9039; my first experience with such movement. I hand wind my watches to get them going... or did, as I'm more careful with the 2824 based movement watches I still have. But the new Miyota winds very smoothly and just runs a bit fast (which I prefer to a bit slow). So I would only avoid the SW200 if you are prone to wind your automatics more than not.

I don't think the movement is the biggest contributor to the price in this price range. Personally, I wouldn't mind much if any watch I like has either of them and I could see the price justified based on the build materials and the design.

I have several watches with the SW200 family, but none with the Miyota 9000-series but this is by accident.

I've had 3 Sellita SW200 movements crap out on me - two from new, and one after a year. All covered under warranty, but...

Not only do I think the SW200 in the CW is not worth an additional $400, I'd buy a watch with a Miyota 90xx for +400 over the same style with SW20o.

The SW210 does not suffer from the hand-winding fragility of the SW200. There are several reasons for that, starting with the fact that the SW210 cannot possibly have the helicopter rotor issue that occasionally afflicts the SW200, so hand-winding the SW210 will never involve the excessive force required to drive an auto-winding module, and continuing with the fact that hand-winding the SW210 goes through a 1:1 gear ratio that, in the SW200, is a 2:1 ratio implying smaller and more fragile teeth in the ratchet wheel, compounded by the fact that the SW210's ratchet wheel is steel whereas the SW200's is brass.

That makes total sense. I forgot that the major point of failure with 2824/SW200 are the reversers used for the bi-directional winding system....that are only needed for an automatic winding rotor.

Folks talk about “reversers…” is that a more complex/fragile system than the Seiko Magic Lever for the bi-directional winding? Over here winding in one direction Miyota land 🤣

Generally, no. Seiko themselves used reversers instead of magic lever (as well as Incabloc instead of Diashock) when they made 4L, which was their ETA-2892 compatible movement.

2824/SW200 reversers specifically are known to occasionally get stuck. I don't know if STP 1-11 or Soprod P024 have the exact same weakness.

There's surely some irony involved, where you are better off starting up your 2824/SW200 with the "Seiko Shuffle" needed to get a 7s movement going. One you better not handwind, the other, you can't... No fears, hand winding a 90xx or 4Rxx movement.

Or LJP G100, or (presumably) Ronda R150. Both are size compatible with 2824, but neither is a clone of the 2824 design. If STP 1-11 does share the winding train weakness, the changes made to the new 1-21 caliber might've attempted to address that. There's no detailed info on what exactly STP did to create 1-21 though, at least not that I could find.

Anything using the 2824-pattern auto winding module is prone. Even the new C07s have reportedly exhibited it.

Looking at the technical docs for the 1-21, it appears to still be a 2824 clone like the 1-11. Certainly the winding train, including the auto winding, is the same arrangement.

I’ve had multiple watches with both movements and if the same watch was offered with both movements I’d take the Miyota, especially if it was cheaper. Christopher Ward is a nice watch and I wouldn’t be put off by the Sellita. I’ve had good luck with both movements.

I have several with both.
No problems with either movement across a span of several years for the oldest ( about 12 for theoldest Selita)
and also consider how many of each of these are churned out - there's bound to be a few duds in both camps and people always complain more about failures than praise flawless behaviour - by about 20 to 1

I've had 3 Chr Ward's nd still have one and their service is outstanding and their quality is pretty top notch.
the other microbrand would need to be pretty exceptional to better them on all fronts.
The Cost of the movements would have an impact - just look up the replacement part cost online- but the other factors involved in a watch would have more impact.
Where is your other micro made, assembled and tested?
Its unlikely to be in it's home country, so bear that in mind in the value equation
