Alot of interesting watches being shown here. The WW2 period Glashutte Tutima pilots chrono is a rare bird and the pride of any vintage watch collection. I really enjoy the history of Universal Geneve as they are rich in military watch production. I have repaired and restored many of these early complicated timepieces around the world for many dealers and collectors alike. The same goes for all Heuer watches especially the Carrera models as they have a strong racing history. If you can find any of the early Longines or Omega wrist or pocket chronograph watches used as timers in racing circles those are definitely hotter than hot !
