A lot of write-ups about that limited edition timepiece advocate that Seiko was 'commemorating' the 1964 Seiko Crown Chronograph. However, it was the movement that was being recognised (for more, visit this article I wrote). I was actually surprised that a lot of people got that wrong. Even the design of the SRQ031J1 looks different when compared to the 1964 Seiko Crown Chronograph.
This time around, Seiko launched three specific models with different dial colours to commemorate the 1964 Seiko Crown Chronograph. These models are limited editions and only 1,964 units of each model will be produced. Visually, these new limited edition models have more in common with the 1964 Seiko Crown Chronograph than the SRQ031J1. Nevertheless, these new models are not chronographs unlike the 1964 Seiko Crown Chronograph.
