Only at Armin Strom, however, will you see all these tasks being performed in such a compact space at one of the industry?s smallest, yet no less capable, ?manufactures.?
No new watch movement would ever see the light of day, however, were it not for the original ideas of the engineers and watchmakers behind them.
