The Sellita SW200-1 is the main competitor to ETA’s 2824-2 workhorse. It has been updated from SW200 to SW200-1.

Many reputable watch companies are using this movement as an alternative to the ETA mechanism due to it being more economical and readily available.

You may have seen this movement written as the SW-200 but according to Sellita, the correct way to spell this caliber number is SW200 without a hyphen.

4 Grades of SW200-1:

Just like the ETA caliber 2824-2, there are four grades of the SW200 movement:

  • Standard – adjusted in two positions; accuracy of +/-12 sec/day up to +/- 30 sec/day
  • Special (Elabore) – adjusted in three positions; accuracy of +/-7 sec/day up to +/- 20 sec/day
  • Premium (Top) – adjusted in five positions; accuracy of +/-4 sec/day up to +/- 15 sec/day
  • Chronometer – COSC criteria

How to tell the difference between grades?

One way to distinguish between Standard/Special and Premium/COSC grades of the SW200 is to look at the anti-shock device:

Standard Novodiac
Special Novodiac
Premium Incabloc
Chronometer Incabloc

Sellita Date Codes:

Under the balance wheel, near the caliber number engraving, you may have seen what looks to be a laser etched code containing DM and XYZ.

  • DM means that the movement origin is from Sellita Watch Co.
  • XYZ is a Sellita code (we’re not sure the meaning, comment below if you know)

As for the date part of the code, new movements produced in 2018 look like this:

  • DM18.1/XYZ = JAN+FEB
  • DM18.2/XYZ = MAR+APRIL
  • DM18.3/XYZ = MAY+JUNE
  • DM18.4/XYZ = JULY+AUG
  • DM18.5/XYZ = SEPT+OCT
  • DM18.6/XYZ = NOV+DEC

There is also a code for what Sellita refers to as “Renewed Movements”. The meaning of this still needs to be confirmed, but it appears that this is for movements that were sent back to Sellita for renewal. Perhaps brands are able to buy them at a discount. We still don’t know, but please check your movement for a two digit number starting with 2X. For reference:

Renewed Movements
A 2-digit customer service code is engraved to show that the movement has been renewed.
20 for 2020, 21 for 2021, etc.

Case study pics coming soon.

Crown/Stem Removal:

Official Sellita documentation states that the crown should be in the time setting position before being extracted. Use a 1mm screw-driver, avoid using tweezers or any other tool with a point because this could jam the setting lever and damage the setting lever spring.

I believe I have watches with this movement, but I also think most sites state SW200 and not SW200-1 even if has an SW200-1 so I have no idea unless I open up my watch. If there is a difference enough for Sellita to add a 1 to the number then there is probably difference enough for companies to state the correct movement, don’t you think?

I thought Sellita uses Incabloc, but that isn’t Incabloc in the picture.

That’s borderline criminal. Some of these hollow brands are just trying to take advantage of the ignorant/new watch enthusiasts. It’s a shame.

I have the watch, but I received it through a subscription to Watch Gang, which is $299/month. I think that’s primarily how people would get this one.

My Oris 01 733 7613 4114-07 8 24 75 uses he SW200-1 movement. I’ve has the watch 10 years (albeit rarely use it), never serviced and after a week it’ll be 6 second fast according to the World time clock. A reliable if somewhat an undesirable movement.

You asked for folks to mention if they own a watch with the SW200-1. My Ginault has one.
I screwed up the original movement trying to adjust the beat rate. I sent it back to Ginault and told them I screwed it up. They tried to adjust but felt anymore time was not cost effective and asked if they could put in the SW200-1. I have no problems with this movement so I said yes. Got it back a few days ago and so far so good.

A ton of entry-level Tudor’s use ETA 2824…If I’m not mistaken a lot of these companies modify and refinish the movement once they have them. I think that’s why a lot of brands use their own caliber name to look different but are based off of ETA/sellita movements.


I had two watches with the Sellita SW200-1 experiencing winding issues. The first was obviously missing teeth from the 2 winding gears. You could see gaps in the wheel as it turned and that made it skip when manually winding the mechanism. I have no idea how this could happen. The other watch looked like the teeth were 100% intact but manually winding the mechanism gave a skipping sensation and would not wind it up.

My question is has anyone else in this forum experienced winding issues with the SW200-1 mechanism?


Is ETA made by Sellita or the other way around?

You list the Rebel Aquafin Diver in the known models. I have one of these watches and I can’t wind it. The issue is that it like skips around or slips when winding. Does anyone know why or how this could be possible? Other people complained about it too, but instead of complaining, I just want to know why and how they managed to have this movement unable to wind. I had an Oris with this movement and it was perfect.
