WatchZone readers here is a first look at the new Jaeger-LeCoultre
Duomètre Unique Travel Time. The piece you see here is a 100 piece
limited edition in a 42mm white gold case available exclusively from
November 2012 at the brand’s Paris boutique (price: 37,500 EUR) —
non-limited edition model(s) are expected at SIHH Geneva in January
2013. Follow on below as I run through the high points — including an
explanatory graphic which highlights the numerous operations of the
watch as seen on the dial.
A new member to the already impressive Duometre family, the Unique
Travel Time and its JLC Caliber 383 follows watches such as the JLC Duometre Spherotourbillon (Caliber 382) and the Duometre a Quantieme Lunaire (Caliber 381).
The watch uses the “dual-wing” concept of the Duomètre-line which is
one escapement but two independent operating gear trains and two
barrels. But before we get in to the particulars of the new
Jaeger-LeCoultre Caliber 383, let’s turn to the dial.

Note the symmetrically arranged and well balanced subdials: at 2
o’clock is the hour and minute for home time; at 10 o’clock the hour and
minutes of the worldtime. Specially for this model, the digital
numbers 7 and 9 are specially applied in red pay tribute to the
Jaeger-LeCoultre Boutique at Place Vendôme, Paris.
Here is an overview of the key dial elements. The grained dial is
made of silvered brass. Not highlighted but still on the dial in my
graphic are the central seconds hand and also the dual power reserve
meters below each sub dial.

The day/night indication and the hours disc are placed at 6 o’clock
and presented via world map which turns. I find the execution of the
world map, though domineering on the dial, to be somewhat lacking in its
aesthetic appeal. Hopefully this is something that can be spiffed up
for the final production models vs. what is shown here in the press
photos and what I have seen in live prototype pics.
Jaeger-LeCoultre Calibre 383
The first barrel provides 50 hours of power for home time and
associated gear train, the other barrel provides 50 hours of power for
the travel time/second time zone — independent, but both regulated by
the same escapement. The same crown serves to wound both barrels, turn
it clockwise to wind one barrel, turn clockwise to wind the other. The
operation of the dual time-zone display does not in any way influence
the running of the watch, a fact that considerably enhances the
precision of the watch.
As with any Duometre movement, the Cal 383 has received special care
in the finish. The Caliber 383′s bridges and gear train are
hand-chamfered and feature polished troughs. The wheels, also
hand-chamfered or adorned with polished troughs, are snailed or
softened. JLC notes that this decoration draws its inspiration from the
great tradition of the brand’s pocket watches while setting new
standards with its unique finishing. The back also bears the engraved
names of cities corresponding to 24 time zones.
The Duomètre Unique Travel Time watch in 18K white gold is a limited
edition of 100 copies, and was specially created for the opening of the
Jaeger-LeCoultre boutique in Paris’ Place Vendôme, where it will be
available starting on 20 November 2012. Price for the Jaeger-LeCoultre
Duomètre Unique Travel Time is 37,500 EUR (about $48k US at current
f/x). All in all a nice piece, though my arm’s length opinion is that
it is not as impressive as other members of the Duometre collection and
it is hard for me to get excited about this piece.
