My name is Christoph. I am from Vienna, Austria and collecting sports-watches is one of my big hobbies. Recently I bought my first vintage Doxa - a Sharkhunter with Aqua Lung dial.
I would like to ask the vintage experts among you if the crown (signed "Doxa") of this model is correct and if the crown should be a screw-in-crown or not. Currently it is a non-screw-in-crown. Also I would like to know if the case-back is correct for this model.
Hope you like the pictures,
best regards and thanks for your help
