When thin was in.....Piquette powered by a very thin Peseux 7000 series movement, the basis for a number of other calibres -- e.g., Junghans J815, Montblanc MB23.01, Omega 651, among others.
I really like it, I recommended Nomos as a Brand to many of my friends but never bought one myself.🤦
It wears great on my small wrist and due to the very thin case (under 7mm) it fits easy under a cuff.
The movement has a finishing that I find pleasent and overall it feels solid and well build. I really like that the details are well done. The coolest part of this Ref.173 is the black dial, that is less comon than the white and the moving power reserve. If you can get one used you are having a great deal. 👍
