This is a Zeppelin mechanical chronograph from 2013: It has a Soviet made 3133 mechanical movement. The watch face is a black chronograph with 3 dials. I have been using this piece for the past 9 years. It shows light use tear around the body. The sapphire watch face is spotless. The sapphire back glass is also scratch less. The movement is really beautiful with gold decoration. The rewind is manual and it’s smooth like the first day. I haven’t measured the accuracy but I think it keeps within 2-3s every day. The bracelet is a leather brown aviator I bought on Amazon. The watch is very hard to find, I’m only parting with it because I don’t wear watches anymore. Only offers above 450$, thank you.
