Story: 

Constantin Weisz Watches - this is a German company based in picturesque Cologne, just meters away from the Rhine. 
Constantin Weisz - high-tech meets tradition. 
Only Constantin Weisz can offer you: on the one hand, modern casings fashioned using cnc techniques, with laser-cut hands and indices. On the other hand, patinated marvels showcasing the art of the watchmaker. This is something quite exceptional.
We offer "new old stock" - historical - yet new - watch movements. That might sound like a contradiction, but it isn’t. We have watch movements that date from between 1920 and the turn of the century – produced by traditional Swiss manufacturers, such as Adolph Schild, Unitas, Fleurier, Venus, to name but a few. So come with us, as we dive back into the glory days of the Swiss watch industry and bring a piece of history back to life.
In Short - Constantin Weisz is not just a watch - It's a sample of watch history.
