this is a nomos tangente sport I bought and was running great, until one day I pulled crown out and the crown pin came out. I brought it to a local watchmaker and he said it was the detente that broke, it's something that connects to the crown pin or something. I am selling as is without the bracelet. comes with the box . in the zip lock bag is the piece of the detente that thf watchmaker found inside. he did not have the part so he suggested I send it back to nomos, which might take a couple months. I've decided to sell as is and buy a new model I've been interested in.
