People often say that the lunar period indicator is the most feminine complication. It is certain that it brings a poetic aspect to the dials, but many male collectors are passionate about astronomical functions, which are sometimes very complicated. The Moon-phase is the most common.<\/p>\n\n\n\n

\"Longines
The Longines Master Collection Moonphase timepiece comes in many versions; one of them is this feminine edition with a 34 mm diameter dial.<\/strong><\/figcaption><\/figure>\n\n\n\n

Moon-phase: decoration and accuracy<\/strong><\/strong><\/h2>\n\n\n\n

Romantic and technical, the display of a Moon-phase requires a lot of savoir-faire. The craftsman decorates the rotating disc based on different methods to create a mini starry sky featuring two opposed moons. They normally appear one after the other thanks to a half circle aperture. The master watchmaker conceives very elaborate systems that follow, in the most precise way, the natural phases of the heavenly body.<\/p>\n\n\n\n

Longines Master Collection, classical and chic <\/strong><\/strong><\/h2>\n\n\n\n

A classical element that displays the phases of the Moon (see \u201cthe different Moon-phases\u201d) is at the heart of many Longines automatic watches of the Master Collection line. <\/p>\n\n\n\n

This elegant steel 40\u00a0mm timekeeper for men (\u20ac\u00a02,190) also features the complication. Placed at 6 o\u2019clock, it powers a\u00a0beautiful\u00a0guilloch\u00e9 \u201cbarleycorn\u201d silver dial. The discreet relief pattern recalls, from close up, the fabric of a shirt.
With painted Arabic numerals bearing blued \u201cleaf\u201d hands, the design is classical and well balanced.\u00a0<\/p>\n\n\n\n

A Moon-phase Longines watch for women<\/strong><\/strong><\/h2>\n\n\n\n

A high-performance calibre <\/strong><\/strong><\/h2>\n\n\n\n

One is for men, one for women, but both feature the same Longines calibre L899, an automatic movement of latest generation.<\/p>\n\n\n\n

\"Longines
Whatever the version, the Longines Moon-phase watch unveils on the back a self-winding calibre L899.<\/strong><\/figcaption><\/figure>\n\n\n\n

This beautiful Swiss mechanic is visible on the case back. With a confortable power reserve of three days, the calibre decorated with Geneva stripes on the oscillating weight features, like the dials, the brand\u2019s winged hourglass: the emblem of the watchmaking Maison. It also holds an anti-magnetic silicon balance spring.<\/p>\n\n\n\n

Like any Longines models featuring this type of spring, these two timepieces have both an extended warranty of 5 years.<\/p>\n\n\n\n

More and more accurate Moon-phases<\/strong><\/strong><\/h2>\n\n\n\n

We\u2019ll say it right away: it is mechanically impossible to indicate the lunar phases with perfect accuracy. Even if the masters watchmakers increase the number of teeth on the wheel that makes the Moon-phase disc rotates, there will always be a time lag between the two, and the watch will have to be reset one day or another. <\/p>\n\n\n\n

The real duration of a lunar phase cycle is 29 days, 12 hours, 44 minutes and 2,8 seconds (very precisely). However, on classical mechanisms, the duration is calculated on 29,5 days. It thus leads to a time lag of one day every two years, seven months and about 20 days. On most complicated models, including the commonly named \u201castronomical\u201d Moon-phases, the time lag happens every 122 years. <\/p>\n\n\n\n

Some manufactures go even further! Indeed, the resetting is done every 577,5 years on the IWC big pilot\u2019s watch with perpetual calendar spitfire<\/a>. Better yet, the time lag on the A. Lange & Sohne 1815 Moonphase anniversary edition<\/a> happens every 1058 years. Yes, you read it right: more than a thousand years! And what can we say about the ATMOS collection classic moon designed by Jeager-LeCoultre<\/a>? Even if it\u2019s a table clock and not a bracelet watch, it only needs resetting every 3821 years\u2026<\/p>\n\n\n\n
