The Automatique Lune is the moon phase Journe sells now, and it is the second version of a watch that first appeared in 2007. The original pushed the hours and minutes back to the middle of the dial, away from the off-center layout the Octa family had used since 2001, and it made the moon and the large date the things you notice. The 2019 revision kept that arrangement and rebuilt it: bigger date, redrawn moon on a sapphire disc, larger crown, and cases at 40 and 42 mm instead of the earlier 38 and 40. Platinum with a whitened guilloche silver dial is the cool configuration and the one that shows the most detail on the surface. It is a current reference, still built to order rather than to stock, and nothing else in the range does the same job.
Platinum runs at 40 or 42 mm and 10.7 mm deep, polished, with a knurled crown that carries the silk-rope motif the house uses across the collection and is sized to be turned easily rather than to be admired. The dial is whitened guilloche silver with a Clous de Paris field worked into the center, printed numerals around the outside and a railroad minute track at the edge. It is a solid dial rather than a plate with rings screwed onto it, which is the visual difference between the Automatique Lune and the older off-center Octa watches. The date aperture measures a little under five millimeters across, enlarged in the 2019 revision because the earlier window was tight, and it sits at the top of the dial. The moon shows through an opening low on the left, rendered on a sapphire disc so it appears to float rather than sit on a painted background. Small seconds run at half past four. Teardrop hands cross the whole face, and the printing on the current dials is blue rather than black. Both diameters share the same dial drawing, so the 42 mm version carries a wider band of silver at the edge. Both are also 10.7 mm through, which is the standard Octa height and the reason a watch with a moon and a large date still slides under a cuff without effort.
Three things happen on this dial beyond the time. The large date changes instantly at midnight, driven off the winding train rather than by a slow cam, so the two discs snap over together instead of drifting through the small hours. The moon phase advances one step with it and is set up so that it will not need correcting for a very long stretch, which is the standard measure of a serious moon display. And the seconds run in a subdial at four thirty, tucked below the time rather than centered on it. The winding is automatic, through an off-center rotor in 22K gold that turns in a single direction on a self-locking ball bearing system, which is the arrangement Journe has used since the Octa base was introduced and the reason the watch keeps running through irregular wear. Everything is corrected from the crown, in different positions, with no pushers on the band and no correctors in the lugs. That is a deliberate constraint across the whole collection and it is the reason these watches are easier to live with than most calendar pieces. The moon and the date are the only two indications that need any thought at all.
The moon phase has a long line in this house. The Octa Lune of the early 2000s put it on an off-center dial with the time in a subdial to one side, a layout that suited the family but demanded some effort from the reader. The Automatique Lune of 2007 answered that by centering the hands and simplifying the face, and it has been the more approachable of the two ever since. The 2019 revision that produced the current reference is mostly a legibility exercise: the numerals at three, eight and ten regained their full form when the subdial and the indications were reduced in size, the date grew, the crown grew, and the case sizes moved up. Alongside it Journe kept the older Lune in the catalogue as a separate reference at 40 and 42 mm, so the house currently offers two moon phases with two different philosophies. There is also a Nacre version with a mother of pearl ring, offered only through the boutiques, and a Black Label execution in platinum with a dark plate. Between them the moon phases account for a large share of what the automatic base is used for today. That concentration is recent. Twenty years ago the automatic family was spread across a calendar, a chronograph, a world time watch and a moon; most of those have gone, and what is left leans heavily on this one indication.
A moon phase is a decorative complication and everybody involved knows it, which is why the interesting question is whether the watch justifies it. This one does, because the moon is small, sits low on the dial, and is rendered on sapphire so it looks like an aperture onto something rather than a picture. Platinum with a silvered dial is the version that shows the guilloche most clearly, since there is no color competing with the texture, and it is the configuration most likely to be described as the classical one. The 40 mm case suits a wrist that finds current dress watches too large; the 42 mm is the one most buyers order. As a current reference the obstacle is delivery rather than condition, and configuration is worth deciding carefully because the two sizes read differently. The strap version is the default and a platinum bracelet was offered on some executions. Anyone choosing between this and the older Lune should handle both, because the layouts ask for different things.
