Earlier this month Longines introduced a new 24-hour second time zone watch, the Conquest 24 Hours.  The watch features a second time zone, displayed via the central red hand, which sweeps the dial every 24-hours (vs. a 12-hour sweep which is also often used on GMT watches).   The watch has a 41mm case and is available in silver, blue, and black dialed models.  The Longines Conquest 24 Hours uses an ETA Caliber A07 171, from the Valgranges line of ETA calibers (see “Did You Know” below).  Nice looking watch in the sub-$2,000 price range; the polished crown guards are a nice touch.  Price is $1,600.

Did You Know?

Following a centuries-old tradition, watchmakers use lines rather than millimetres to describe the size of the movement’s diameter.  The line, or Parisian line, is an ancient watchmaking measurement that predates metrification and is a direct descendant of the French pied (foot) measurement used under the Ancien Régime.  Each line is equivalent to 2.2558 mm, which is rounded up to 2.26 mm for ease of calculation.

Calibre Valjoux: 13 1/4 lines or 29,89 mm
Calibre Valgranges: 16 1/2 lines or 37,22 mm
