Tutima is a watch brand from Germany. They have just recently announced the introduction of of an all in house movement. Now the movement and module are considered by most as some of the finest Europe has ever produced. It was made by ETA strictly for Sinn, Tutima and one other house. Sinn and the others, not Tutima, stopped using it several years a go. And it was only a question of time before N. Hyak, chairman of ETA, among other, decided to stop as the the stamps, gears and everything were worn out. The chronograph module is considered as one of the finest if not the finest ever produced. The Tutima watches are standard issue to the German and other NATO countries. This I can attest to, prior to my retirement from the USAF reserve, assigned at Holloman AFB IN New Mexico, I saw every German member of the the German contingent sported a SS and 18k YG Tutima. Not only has Tutima produced their own movement and module, they relocated a portion of production to a new facility in the same town as Glasshaus, Lange. Tutima has been in the watchmaking business since 1927. WWII threw a wrench at Tutima, along with other notable German brands. Tutima now has three manufacturing facilities in Germany. In the US they have a distribution and full service center. They have a web site and it maybe worth a look.
