This is a watch from the 1940's made for the swedish military similar to the suverans. The size of these watches is smaller that 36mm of the suverans and are around 33mm although they do wear bigger. The lug space is 16mm. PerK has 3 of these so i guess i will have to buy another 3 to make 4 
. I bought this one from another Swedish collector Martin.
