I have just purchased a 47mm Steinhart, the quality is exceptional.
So given the £220 difference what would you be getting extra with the Stowa apart from a different name ?
Do they use the same movement ? if so, what would you be getting for the extra £220 ?
Also have a look at Archimede, they do a good range and variety of this type of watch.
