关于COSC部分LZ应该弄错了。
官网信息
Upon request, all STOWA watches can be enhanced with a COSC certified movement.
When you're selecting a watch, you will be given the option to choose a COSC movement. If you do choose to order your watch with a COSC movement, there will be an additional charge of 177 EUR. When it's ready, your STOWA watch will arrive with its COSC papers.
If you already own a STOWA or Schauer watch, you can ship it back to us and we'll fit it with a COSC movement, which is guaranteed for two years.
We apologize, but we cannot sell individual movements.
