This year JLC has updated its perpetual calendar watch with the new Jaeger-LeCoultre Master Eight Days Perpetual 40 (ref. Q1612520) timekeeper. Now available in an 18-cart rose gold case and still featuring the same sophisticated, slightly off-white dial with lots of sub-dials and other indicators, the watch still makes a very strong impression and may be a very interesting choice for a person looking for a dressy “complication” watch.
The main difference between the two models is, of course, the size of the body.
For years watches were growing in size from modest and elegant 38 millimeters in diameter to heavy-weight monstrosities up to 45 millimeters wide.
It seemed that there was no end for this trend, but, surprisingly, the last year the tide has turned and serious watchmakers started to re-introduce their most popular models in less intimidating bodies.
Since the dial of the watch basically remained the same (with only minor styling differences, but the same layout of numerous indicators and sub-dials,) the weight-loss program was limited to the timekeeper’s bezel. It has become visibly thinner, providing the watch with more slender, more graceful appearance.
Judging by the official specs, the watch is still powered by the same JLC Caliber 876-440B hand-wound movement.
Featuring a twin-barrel design, the watch offers as many as 192 hours (8 days) of guaranteed power reserve, which is very convenient for a piece that is supposed to be worn only on special occasions and cannot be placed into an automatic winder. In order to keep the watch running, you will only have to manually wind it just once a week.
JLC knows a thing or two about “interface design,” so, despite presenting a lot of date, the dial of the watch sports a highly legible layout.
At 1 o’clock there is a small Day/Night indicator that has a small aperture that turns red between 10 PM and 3 AM marking the time when cannot change the date without a risk of damaging the movement.
The date, month and day of week sub-dials are placed at 3, 6 and 9 hours respectively. As you can see on the photos, the day of week sub-dial shares its space with the moonphase indicator. Regrettably, the latter displays current phase of the moon with a simple hand making the whole display a lot less spectacular.
Of course, there is also a power reserve indicator at 11 o’clock, as well as four-digit year indicator between 7 and 8 hours.
