The Lange 1 Time Zone, which indicates the time at home and in another time zone at a glance, now houses a new manufacture calibre. Ring-shaped day/night indicators assure good legibility and the new daylight-saving time indication is a useful addition
The new version of the Lange 1 Time Zone is characterised by an asymmetric dial with two time displays, an outsize date and a power-reserve indicator. The watch retains the switchable city ring that allows convenient setting of the second time zone.
In contrast to world time watches, the Lange 1 Time Zone provides the time at home and in a second zone at a glance. While the larger time circle shows home time, the smaller of the two time circles can be set to a second time zone by adjusting the city ring. When the time is adjusted with the crown, both displayed times are corrected simultaneously.
One of the key innovations is that the day/night indicators for home time and zone time are at the centres of the two time circles. There, together with the hour hand, they inform the user whether the time indication applies to the first or second half of the day. Featuring blue printed semicircles, the discs rotate once about their axes in 24 hours while the hour hand performs two revolutions in the same period. When it is located in the dial-colour segment, the display spans the period from 6 am to 6 pm and on the blue background from 6 pm to 6 am.
Another convenient feature is a small aperture of the golden arrow applique at 5 o’clock that indicates the reference location for the zone time that has been set. If the aperture is red, the respective city has a daylight saving-time regime. If standard time applies to the city all year-round, the display appears on a bright background.
With the new manufacture calibre L141.1, the 72-hour power reserve is achieved with only one spring barrel. Other details include a classic screw balance and a freely oscillating balance spring crafted in-house and calibrated for a frequency of 21,600 semi-oscillations per hour. With a case diameter of 41.9 mm and a height of 10.9 mm, the timepiece comes in three case/dial combinations: white gold/black; pink gold/argenté; and – in a limited edition of 100 – yellow gold/champagne.
