This is an automatic watch from KIENZLE, the oldest watchmaker in Germany. It's 40mm, making it a perfect size, and features a luxurious design with a skeleton see-through back. I purchased it overseas, so it comes with an international warranty. The belt is not the original. I've had it overhauled and taken good care of it, but I'm selling it because I no longer have the opportunity to wear it. #Junghans #MaxBillDesign #sinn - Brand: Kienzle - Features: Date display function - Case Material: Stainless steel - Band Material: Leather Thank you for viewing.
