Jaeger-LeCoultre Geophysic True Second Hands On

Front of Jaeger-LeCoultre Geophysic True Second

Jaeger-LeCoultre Geophysic True Second as one of the most famous cult-collectible watches not only from JLC. The earlier Geophysic 1958 models, from 2014, which you can take a look at here if you need a quick refresher, were a real crowd pleaser, as you would expect from their very close resemblance to the original 1958 chronometer grade, antimagnetic watches made to celebrate the International Geophysical Year. Front of Jaeger-LeCoultre Geophysic True Second
The deadbeat/True Second complication is pretty straightforward in terms of how it actually works. The principle isn’t all that different from a remontoire d’egalite, actually. The seconds hand isn’t driven directly by the going train of the watch; instead, it’s propelled forward by a spiral spring, held under tension by the mainspring. On the same axis as the escape wheel, there’s a star wheel, against the teeth of which a metal “whip” presses. As the star wheel turns, the whip periodically slips free of the tip of one tooth, before coming to rest against the next; as it does so, the deadbeat/true beat/jumping seconds hand skips forward. This happens once per second.

As with any interesting watch, there’s both a personal and a social aspect to wearing the True Seconds. If you can get behind the idea of a deadbeat seconds complication at all, on a personal level this is one hell of a watch. The movement is top-shelf work. It’s going to be a Goldilocks-range watch in terms of size for probably 95% of you: not too big; not too small – just right, at 39.6 mm in diameter and at 11.5 mm, it feels thin enough to feel very much like what they used to call, in the 1950s, a gentleman’s wristwatch, suitable for daily wear.Side of Jaeger-LeCoultre Geophysic True Second
That slightly anachronistic feel is aided and abetted by the quiet, but very high quality, finish of the case, dial and hands. Everything’s really cleanly done, with lots of low-key well thought out details that add up to a watch that makes a businesslike, sober, but also very beautiful impression.Side of Jaeger-LeCoultre Geophysic True Second  03
The volume really gets turned up a notch when you turn the watch over. Caliber 770 is a very pretty thing, with, as with the rest of the watch, a very soberly dignified, unpretentious, but also very cleanly and elegantly done finish. The first impression one has of the watch overall is that it’s a wristwatch to which some very serious attention has been paid, both in terms of conception and execution, and that’s an impression that a week of daily wear only reinforced.
