After years of searching, I finally managed to snag this piece.
A Grand Seiko 4520-7000 from March of 1969.
It has my favourite movement by far, the 36000bph Hi-Beat 45 Series by Daini.
This case type was nicknamed the turtle shell and was one of the largest watches made by Seiko in that time period.
Most of these have dials that are damaged or have strong and uneven patina, so to find one in this shape took a lot of effort, but I am very glad to have finally got one.
It has a silvery white linen dial and a case with alternating brushed and polished finishing.
Thanks for reading!
