I have no idea about the brand. It is similar to some Stowas and Dugenas I have seen. The dial has (some doodle) - "ank" or "auk"
If anyone has some info ..
Other than that it is really cool 70s chunky integrated bezel octogonal round face square indices red second silver brushed goodie .
And it is run by a great 25 jeweled PUW 1561 movement, with original bracelet in full lenght, in 38 mm stainless steel block case.
Price for this stunning... Something... Is 89$ + shipping from Croatia, EU.
