So several months ago I bought a Lange 1815 Chronograph, that just wasn't running right. I sent it into Lange service, and while it was there bought a Vianney Goldpfeil. Well economically speaking, I do not feel comfortable keeping both. Which one should I keep, I can't decide. Also, the situation is made a little harder in that I can try on the Goldpfeil, but not the 1815. I decided not to wear it at all until I know if I am going to keep it.
