Too many to list (please add your watch to the comments below…)
The Sellita caliber SW200 is the main competitor to ETA’s 2824workhorse movement. Many reputable watch companies are using this movement as an alternative to the ETA mechanism due to it being more economical and readily available. ETA’s threat to limit sales of movements to brands outside of Swatch Group really helped the Sellita option gain in popularity.
Is it SW200 or SW-200?
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. Please reference this page when you see folks spelling it incorrectly so that we can dispel confusion in the community.
4 Grades of SW200:
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
One way to distinguish between Standard/Special and Premium/COSC grades of the SW200 is to look at the anti-shock device:
Differences between SW200 VS SW200-1:
You are looking at the caliber listing for the SW200, but there is a chance that your watch actually has the SW200-1. While extremely similar, they are technically not the same. The -1 is a evolution in the movement and the differences are noted in detail here.
Please allow us to interrupt your gear turning and caliber learning to say thank you. Thank you for being here! Now, back to the movement..
Many brands are listing the incorrect movement in their specs and marketing. The confusion sometimes occurs because many movement manufacturers use A (Seiko for example) or 1 for the first version of the movement. Sellita’s first version is simply SW200.
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.
Examples of the SW200:
Pictured is the SW200 in an Invicta Ocean Ghost Diver. There are many models with this movement, please comment below if your watch has it and tell the Caliber Corner community what you think of it.
