The Master Grande Memovox model is equipped with an alarm and a perpetual calendar featuring a mechanism that takes
into account the length of the current month (28, 30 or 31 days) and counts a February 29th every leap year.
The alarm is equipped with an original feature that gives the user a striking mechanism.
All these data are linked together by an ingenious system, a genuine programming feat that is entirely mechanical :
one need only set the initial date and all the functions will subsequently follow on correctly in sequence.
Our time measurement is based on the Gregorian calendar, i.e. a year of 365 days, 5 hours, 48 minutes and 46 seconds, or
in decimals 365.242192 days.
one need only set the initial date and all the functions will subsequently follow on correctly in sequence.
Our time measurement is based on the Gregorian calendar, i.e. a year of 365 days, 5 hours, 48 minutes and 46 seconds, or
in decimals 365.242192 days.
In practice, the excess yearly one-quarter of a day (0.242192) is corrected by the February 29th in leap years. The few
missing decimals are then compensated for every 100 years, by eliminating the February 29th.
To ensure greater precision, this elimination is not performed when the number of centuries can be divided by 4.This was
the case in the year 2000 (20 being divisible by 4), which was a normal leap year. It is therefore only in the year 2100 that
the programming of your Master Grand Réveil’s perpetual calendar will have to be corrected. Until then, your watch
will count the days, months and years correctly, allowing for leap years.

will be Monday March 1st, due to the above-mentioned centuryyear compensation system.

The «1000 Hours Control» test
by Jaeger-LeCoultre
Jaeger-LeCoultre subjects its watches to the rigorous «1000 Hours Control» test programme. Unique in its kind, this test
consists of 1000 hours of comprehensive, stringent checks. The «1000 Hours Control» seal or marking, affixed or
engraved on the back of your watch, certifies that it hasundergone this observation programme in our laboratories
and has successfully passed all tests. The latter include rate regularity checks, reactions to changes in temperature and
barometric pressure, resistance to shocks and magnetic fields, as well as water-resistance tests at pressures of 3 atmospheres.

Your watch is therefore capable of withstanding the trials of everyday life when you wear it on your wrist.
The criteria of the «1000 Hours Control» programme go far beyond the official timekeeping test standards, which concern
only part of the movement. Jaeger-LeCoultre tests both the movement and the fully cased-up watch.
