This Tressa is a beautiful example of diver watch from late 60s.
All stainless steel case , black dial with three-dimensional hour markers, bi-directional rotating bezel, hi-quality 25 jewels automatic movement Felsa 4462 and original tropic strap make this watch typical vintage diver.
All macro images of watch shows details that you cant notice with naked eye.
Important Notice, this model is mostly not made in all stainless steel but this one is full stainless steel case model and it makes it very rare.
Movement is serviced and keep time great.
Great retro diver.
