It’s crown position at 4 o’clock

Besides being the first Grand Seiko to use an automatic movement, it has the distinction of being the only Grand Seiko to have its crown located in the 4 o’clock position. This was because it’s designers believe that with its automatic calibre in use, there was no need to have the crown located in the traditional 3 o’clock position, and believe a recessed 4 o’clock position provides for better symmetry as well as wearing comfort.
