Patek Philippe

german silver

 

i have read that german silver is delicate and can discolor with finger oils and is softer. thats why lange watchmakers wear those little finger glove things. but i never connected that it makes lange movements easier to finish. does it affect movement durability or reliability? i also have this question with journe movements that are made from 18k, does that make journe movements less durable and reliable?
