This Tressa is a typical example of dover watch from late 60s.
All stainless steel case , black dial with three-dimensional hour markers, bi-directional rotating bezel and hi-quality 25 jewels automatic movement and vintage tropic strap make this watch really serious and desirable collectible diver watch.
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.
