I have the Sinn. Great field watch. Awesome all around except clasp is a little tough to open. Fingernail needed. I’ve tried the formex on at a watch meet. Nice. But can’t say much more as it was for a minute or so.
Haven’t had the courage to tackle a chronograph yet. Actually I really spend about 50% of my time scanning the floor for dropped parts. I was at a GS9 event last year where the GS watchmaker was taking apart and putting back together a movement. He also dropped a part. Happens to all of us I guess.
The blue is amazing. Changes from black to brilliant in direct Sun. The case is my fav. Movement in back is the cherry on top. I like it on my custom strap. My bracelet has never been used.
