Yes, it is called Flake but it is not the same with the Diamond Flake that I wrote about HERE. This one is thin indeed, but because it has a date feature it is not the thinnest. Either way, it is a beautiful simple watch.
This model was made in the mid 1960’s, and mine is from 1966. It comes on a bracelet and is made entirely of stainless steel. The dial is simple, with applied polished hour markers and a date window at 3 o’clock. Nothing fancy about it, just one honest, clean, timepiece. The movement, calibre 2710, is a hand winding one and has 22 jewels. There is one more version, the Diamond Flake Date that has 25 jewels. I will write about that one later. 🙂
