User manual TISSOT MOON PHASES WATCHES

[. . . ] Your watch is equipped with an ultra-flat quartz movement delivering extremely high standards of precision and operation and the dial displays hours, minutes, seconds and date (with day and month), with a moon phase display programmed for the next 10 years into the future. After initial setting, all you need to do is to make adjustments to the settings whenever the battery needs changing. Initial setting of your wristwatch is performed in accordance with the moon phase calendar provided at the end of this User Guide. To ensure that your watch operates with perfect precision for many years to come, we advise you to pay very careful attention to the advice provided hereafter. ® 1 New moon 2 1 Waxing moon 8 On the 15th day of the lunar cycle (fig. [. . . ] Setting the day of the week Pull the crown into position III and move backwards and forwards between 23 : 00 hrs and 01 : 00 hrs (11 p. m. Note : Due to the fact that this operation alters the date, this then has to be corrected by pulling the crown out into position II and turning it. Setting the date and the month Pull the crown out into position II and turn it forwards until the correct date (4) is displayed. During this operation, your watch will continue to function normally, so you will not need to alter the time. When the date changes from the 31st to the 1st, the month indicator advances by one month. Since the display for phases of the moon was programmed in advance, all you have to do is alter the date on months with less than 31 days. Setting the phases of the moon Pull the crown out into position II and turn it forwards until the correct phase of the moon (7) is displayed. Note : For precise adjustment purposes, place the moon phase indicator on the full moon setting. At this point, each jump of the indicator advances the setting by one whole day. The moon changes continuously between these characteristic positions. The time which has elapsed between two new moons corresponds to approximately one month. The orbit of planet Earth around the sun describes what is known as an elliptical path, on a defined plane. Let's represent this plane extending to infinity up to the point where it intersects the sphere of fixed stars. Alongside this circle is a range of constellations, familiar to most of us as the constellations of the zodiac: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces. If it were possible to see stars during daylight hours, we would observe in the course of a calendar year that the Sun, when viewed from the Earth, passes in front of each of the twelve constellations of the zodiac from right to left, being in front of a different constellation at each point in time. The lunar orbit around the Earth shares almost exactly the same elliptical plane as the Earth describes around the Sun. It follows from this that the Moon's orbit also causes it to pass in front of this group of constellations. Due to the regular and repetitive nature of this movement and its phases, the moon has always served as a means of counting the passage of time. Indeed, this is why the lunar calendar is still used for timekeeping purposes. We are thus able to order our lives in terms of the lunar cycle. The rhythm of natural phenomena also has a profound influence on people, animals and plant-life. [. . . ] Type : Renata 373 / Service life : about 3 years.
