One of my favorite tuning fork watch is this one, I wear it with pleasure very often.

40 years old but always modern design, fantastic movement, hi quality solid stainless steel build, bakelite bi-directional bezel and screw crown make this watch more valuable. Of course perfect working and cosmetic condition, dial and hands is without any dust and oxidation which is quite common in this model.

This model was made in the white dial version too, it can also be found with an automatic movement, but for me tuning fork version (F300Hz) is the best.

Produce date is in mid 70s.
