Longines 180th Anniversary Collection: The Longines Telemeter Chronograph & the Longines Tachymeter Chronograph

To mark its 180th anniversary, Swiss luxury watch brand Longines introduces two new models: Longines Telemeter Chronograph and the Longines Tachymeter Chronograph, which represents both the brand’s rich history and extend Longines’ Heritage segment with a combination of extraordinary technical features and a touch of elegance.

Longines Telemeter Chronograph
One of the significant characteristics of this timeless and elegant model is its telemeter scale on the dial, inspired by a beautiful chronograph produced by Longines in 1933. Telemeter scales were initially introduced around 1852 to measure the distance travelled by sound. Activated right after the flash of lightening and stopped when the thunder is heard, the hand of the chronograph shows the distance in kilometers of the phenomenon.

The circular steel case with a diameter of 41 mm houses the caliber L688, a self-winding mechanical movement with a column-wheel chronograph mechanism exclusively developed for Longines, which can be admired through a transparent case back. The chronograph is equipped with a date aperture at 4h30, a small second at 9 o’clock, a 30-minutes counter at 3 o’clock and a 12-hours counter at 6.
Besides the appealing technical features, The Longines Telemeter Chronograph also attracts the eye by its harmonious design embodied by a subtle fusion of tradition and a contemporary spirit. The white lacquered dial with 9 black Arabic numerals features the red telemeter scale and a spiral tachymeter scale in the same colour. The blued steel Breguet hands, indicating hours and minutes, add a touch of elegance to this exceptional model fitted on a black alligator strap.

Longines Tachymeter Chronograph
The Longines Tachymeter Chronograph features a technical tool initially introduced around 1811 to measure the hourly pace in assembly lines, as well as the velocity of the first modern means of locomotion: the tachymeter. To measure the hourly pace, the chronograph is started at the beginning of a task and stopped once the task is completed. The hand then shows the average production pace per hour. To find out the velocity of a subject, the chronograph is activated at distance zero and stopped once the distance of one kilometre has been covered. The hand then indicates the average velocity in units measured.

The Longines Tachymeter Chronograph now combines in a very unique way the technical specifications of a tachymeter with the values of the brand, namely tradition, performance and elegance. The circular steel case with a diameter of 41 mm houses the caliber L688, a self-winding mechanical movement with a column-wheel chronograph mechanism exclusively developed for Longines, which can be admired through a transparent case back. The model features a date aperture at 4h30, a small second at 9 o’clock, a 30-minutes counter at 3 o’clock and a 12-hours counter at 6.

Besides its extraordinary technical features, the model stands out with its remarkable design. The white lacquered dial is inspired by the one of a chronograph developed by Longines in 1934 and contrasts perfectly with the black Arabic numerals, the tachymeter scale in blue (1000 m) and red (100 m). A subtle touch of elegance is added to this model by its blued steel Breguet hands indicating hours and minutes and the blued steel counter-weight line pear hand indicating the seconds. To complete the traditional yet contemporary design of the model, it is mounted on an elegant black alligator strap.
