Year indication
The year hand indicates the years that are arranged in a
straight line as shown below.
In the widely used Gregorian calendar, a leap year is
roughly defined as a year that is divisible by four.
However, years divisible by four are not regarded as a
leap year and counted as a common year if its quotient
＊
obtained by dividing by 100 is not divisible by four (e.g.,
years 1900 and 2100).
During the period of 1901 to 2099, a leap year occurs at
4-year intervals according to this regularity, and the same
calendared information is repeated on a 28-year cycle.
The year indication scale for this watch is also repeated
on a 28-year cycle. Therefore, the same calendar applies
to all the aligned years that the year hand points to.
(Example: The same calendar applies to the years 1916,
1944, 1972, 2000, 2028, 2056, and 2084.)
