Jaeger-LeCoultre has unveiled a deep blue iteration of its Geophysic True Second that will be sold exclusively on the brand’s website, just one of many online ventures amongst Richemont’s stable of brands, which also includes IWC, Cartier and Yoox Net-a-Porter. The latest model is a variant of the 2015 deadbeat seconds wristwatch, itself based the original Geophysic launched in 1958 to commemorate the International Geophysical Year.

While the ordinary version has a plain silver dial, the limited edition is fitted with a striking blue dial finished with sunburst brushing. Another distinguishing feature is the “crosshairs” in the middle, derived from the dial design of the vintage original. Ironically, the crosshairs are executed as a pair of thicker bars that are wider than the seconds hand and script, resulting in a crowded dial centre.

As with the stock model, the blue Geophysic has a date display at three o’clock, baton hour markers, pencil-shaped hands and lumed dots applied on the flange while the caseback reveals the in-house calibre with a pink gold skeletonised rotor.

Dial colour side, the Geophysic True Second Limited Edition is otherwise identical to the regular production model. Inside is the same self-winding cal. 770 that’s equipped with JLC’s proprietary Gyrolab balance wheel that’s shaped like the brand’s logo and designed for high efficiency as well as easy regulation.

The signature feature is the deadbeat seconds, for which a secondary spring was added near the axis of the second hand. The spring reloads once every second, powering the jump of the seconds hand. This ensures that the extra energy required for the jump doesn’t sap the energy needed to power the oscillator, leaving the amplitude of the balance unaffected. It also has a quick-set hour hand that can be advanced in one hour intervals without affecting the minute or second hands, making it easy to swap time zones when travelling.

The steel case is  39.6mm wide and and 11.81mm high, giving it a compact but sporty profile.
