Earlier this year Jaeger-LeCoultre formally launched and showed off new additions to their much-loved Duomètre collection in the form of the Duomètre Sphérotourbillon, Chronograph, and Quantième Lunaire now in a combination of grey Magnetite dials and red gold cases.
For those new to the Duomètre timepieces, what is special about them is their movement, which is characterised by two independent energy sources (the ‘dual wings’), each devoted to a different function. Two separate gear trains and main spring barrels, one for the time and the other for the relevant complication. The gear trains are connected by a single shared regulating organ.
Today we are sharing with you some photographs of the new Duomètre Chronograph Magnetite, powered by the manual-wind Calibre 380. The second of the ‘duo’ functions for this is, of course, a chronograph. If you’ve ever had a play with this watch in its previous incarnations you will know how interesting the 1/6 second jumping seconds feature of the chronograph function is, although for those unaccustomed to it, it can require some mental realignment.
There are fifty hours of power reserve for both the timekeeping and chronograph functions; turning the crown clockwise winds the main movement for the time function and counter-clockwise, for the chronograph. A single pusher above the crown is responsible for all the chronograph functions.
The grey Magnetite) (a mineral that is an iron ore) is an interesting choice of dial material, especially in terms of texture. The red gold of the case is naturally carried through to the leaf-shaped gold-plated hands and markers.
It is in a 42mm rose gold case with a combination of polished and satin-brushed finishing, and on a brown alligator strap.
As mentioned, there are two other new Magnetite variants. The Duomètre Sphérotourbillon comes in a 42mm 18k red gold case and has the manual-wind Calibre 382 with a multi-axis tourbillon that is equipped with a cylindrical balance with double terminal curves. The tourbillon has a seconds display that can be reset back to zero via a pusher at 2 o’clock without simultaneously stopping the regulating organ. The tourbillon cage is titanium and spins at 30 seconds for the cage and 15 seconds for the axis.
If you have come across the Duomètre Sphérotourbillon already then the dial design will be familiar – the main dial is on the right, featuring the time and date. The seconds sub dial is at the bottom and a 24-hour sub dial for the second time zone, between 11 o’clock and 12 o’clock. Next to each of these sub dials are power reserve indicators for the movement and for the indicators themselves.
Lastly, and we apologise for not having managed to get photographs of it, there is also a new Magnetite Duomètre Quantième Lunaire 42. You can read about the Duomètre Quantième at this link. The model and complication was first launched in 2010, and shows the time with a foudroyante seconds hand showing 1/6th of a second increments, as well as the date and the age of the moon (as per the ‘Lunaire’ name).
The Quantième Lunaire uses the Cal. 381 movement inside this new 42mm red gold case. The watch features two seconds hands; the main one is a centre sweep hand and the second one at 6 o’clock is the jumping (‘foudroyante’) seconds hand accurate to 1/6th of a second. Setting the time is performed by pulling the crown, whereupon both the seconds hands jump to the zero position, leaving the escapement running. Pushing the crown activates both hands simultaneously by re-coupling into the running escapement.
As is the case for all the new Duomètre watches, the dials of these other two also feature rose-gold appliqués and gold-plated hands, and all three come on a chocolate brown alligator strap with a rose-gold folding clasp.
The grey dial/ red gold case combination is a popular one, in large part because this combination seems to give a watch a certain dressy warmth to its appearance. These new iterations continue this trend, and are a fitting addition to the Duomètre family.
