Regarding our year-end and new year's hours,
we will be closed
from December 31st through January 6th.
Thank you for your understanding.
↑This is a Seiko Premier
perpetual calendar model with a Kinetic (quartz movement with a rotor-charging function)
movement.
While it lacks a moonphase, the dial design is
a blatant copy of Lange & Söhne's Langematik—refreshingly so—and
while the big date display being similar can be chalked up to movement constraints,
the size and placement of the Roman indices and the railroad-track-style minute markers
are on a level where there's no getting around it.
If you're interested, try searching for "310.025".
Being a perpetual calendar,
the date wheel also distinguishes whether it's a leap year or not.
What appears in the fan-shaped window in the image above is that display—
the "L.Y." stands for leap year,
and this section advances once per year,
cycling through L.Y. → +1 → +2 → +3 → L.Y.・・・
I'd like to see it click into place at the stroke of midnight on New Year's,
but・・・
（I have actually timed it to watch it, even though it wasn't on New Year's Eve）.
In reality, it moves a few minutes after midnight.
By the way, since it's about to move, the "L.Y." characters are already
slightly offset clockwise.
Addendum:
The date and year are・・・
changed over.
