It seems like Sinn has decided to stop advertising what movement ticks inside their watches. When you click on the "Technical details" tab on any of their watches in the Sinn website it just says "High-quality mechanical movement". And when you click on that sentence the page redirects you to the following text:
In addition to technology, the heart of any SINN watch is the fascinating mechanical movement. We use exclusively the very best quality of movements provided by renowned manufacturers with proven experience with whom we’ve been working for many years:
- ETA SA Manufacture Horlogère Suisse, Grenchen, Switzerland
- Manufacture La Joux-Perret SA, La Chaux-de-Fonds, Switzerland
- SELLITA WATCH CO, La Chaux-de-Fonds, Switzerland
- Soprod SA, Les Reussilles, Switzerland
- Uhren-Werke-Dresden, Germany
The movements are also manufactured in parts in accordance with our technical specifications.
As required by capacities, we reserve the right to switch between the manufacturers mentioned above when it comes to sourcing the movement for a single model. In other words, the movement actually used may differ from that listed in the technical specifications. However, we always use a movement of highest quality from one of the manufacturers mentioned above.
Should you have any individual questions regarding your watch, we’ll be happy to advise you personally.

I have had two bad experiences with SW200-1 and don't want that movement. Now according to their website I might get a SW200-1 movement if I get the watch...
