This Seiko 6309-6100 I had wanted for a while as I liked the idea of a hexagonal case. The green dial was very interesting too. As per usual I bought as a non runner and soon fixed the movement and serviced. The case work took quite some effort as the shape was difficult but also the sides are also angled which made it tricky to keep the shape. I learned allot on restoring this case and actually devised a new technique for myself.
