they're a German brand, that mostly makes tool watches. they made clocks for the instrument panels in planes, and a lot of their watches get inspiration from thatBeen seeing Sinn as of late and, after looking at their design, I am not too sure why. Yes, they are very simple and clean.
Can you share why they carry the prestige?
Personally, looking at the Bulova Lunar Moon....
they make a lot of (modern) pilot watches and divers. their more expensive watches have proprietary tech like 'tegiment' (scratch resistant) steel, and oil filled divers (viewable at any angle underwater). supposedly they're used by German special forces, police, etc., and they have been to space
basically over-engineered German tool watches
