Jacques Deep Sea Chronograph Watches Professional Diving Timepieces From Legendary Models

When diving under the sea, the measurement of time must be reliable and accurate. Any miscalculation of the underwater minutes or the stop of the clockwork will cause serious consequences. Since the launch of Jaeger-LeCoultre’s first dive watch, watchmakers in the watch factory have been committed to providing foolproof security.
   The Jaeger-LeCoultre Deep Sea Chronograph is equipped with a timer running indication function. Whether the timer can start measuring an interval, whether it can be started and whether the measured time is displayed on each chronograph, can be seen at a glance, allowing divers to get greater Protection. This feature was inspired by Jaeger-LeCoultre’s earlier work: Chronoflight chronograph. This chronograph was born in 1930 and is used in the fields of civil aviation and military aviation. This watch further completes the aviation instruments Jaeger has manufactured since 1910. Chronoflight chronograph is equipped with multiple timers and accumulators, which can subtract the stopover time to calculate the total flight time. For more than 30 years, its reliability and accuracy have also been favored by racing drivers.
   Today, the Jaeger-LeCoultre Deep Sea Chronograph draws inspiration from the technical construction of Chronoflight for divers. The dial has a round timer indicator window under the ‘Jaeger-LeCoultre’ logo. It is composed of two red and white dials, which can accurately display the operating status of the chronograph watch. When displayed in white, the timer can start measuring time. Once the timer starts, the indicator window will show both red and white colors, indicating that the time is being measured. Finally, when the timer is stopped, only the red face is displayed in the window, which indicates that the time measurement has ended and the timer has not returned to zero, and the measurement result can be read.
   The Jaeger-LeCoultre Deep Sea Chronograph is a true professional diving watch that complies with all the requirements of the ISO 6425 standard for diving watches. The watch has a unidirectional rotating bezel and 10 bar (100 meters) water resistance. It has excellent shock resistance and anti-magnetic field interference performance, and it is still legible in dark environments. The operating status is indicated by the small second hand at 6 o’clock. Equipped with a new Jaeger-LeCoultre 758 automatic movement, the balance can vibrate up to 28,800 times per hour and has a 65-hour power reserve. The chronograph includes two chronograph dials (hours and minutes) and a central seconds hand. The dial is equipped with fluorescent hour markers and hands for clear display. The crown is located at 3 o’clock, and the two timing buttons are located at 2 o’clock and 4 o’clock, respectively. 42 mm diameter stainless steel case with black leather strap.
   In 2012, two watches that will be entered into the annals of history will continue the legend of the Jaeger-LeCoultre Deep Sea diving watch and inherit its legendary prototype models and the Vallée de Joux workshop since its birth. The precise, reliable performance and creative spirit of today have more than ever met all the demanding requirements of professional and elegant timepiece enthusiasts.
