Radio Controlled Watches
PDF Manual GW-A1100-1AER
Shock-resistant construction protects against impact and vibration.
alphaGEL elements surround the watch, making it even more resistant to shocks and vibrations. alphaGEL is a silicone material. It is extremely flexible and has a cushioning effect on the module.
Solar Power
A solar cell provides power for operation.
Radio signal reception (EU, USA, Japan, China)
Whether in Europe, North America and Japan or in the outer reaches of Canada, Central America and China - once the watch has been set to the local time, it receives the relevant signal and shows the correct time wherever you are. In many countries, it also sets itself automatically to summer and winter time.
A luminous coating provides long-term illumination in the dark after only a short exposure to light.
A built-in direction sensor detecs the magnetic north.
World time function
Displays the current time in major cities and specific areas around the world.
Date and weekday display
The current day and weekday are both displayed.
Fly-Back Function
The fly-back function has been specially designed to meet the needs of pilots. The stopwatch can be reset simply by touching a button; if this is done while the timer is running, the stopwatch immediately begins a new time measurement. This feature allows several split times to be recorded without any time delays.
Stopwatch function - 1/20 sec. - 2 hours
The elapsed time is measured with 1/20-sec accuracy. The watch can measure times of up to 2 hours.
Timer - 1/1 sec. - 1 hour
For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. The time can be set to the nearest second and up to 1 hour in advance - Ideal for people who need to take medicines every day or those who do interval training.
Daily alarm
The daily alarm reminds you of events that recur every day, by emitting an audible signal at the set time.
Automatic hand adjustment
The automatic hand adjustment function checks the home position of the hands every hour and corrects it if necessary — either by adjusting e.g. from shocks or using the influence of magnetism.
Smart Access Technology
Smart Access makes it easy to operate multi-function watches. Simply pulling out and rotating the crown provides intuitive control over all functions
Crown button lock
Secures the crown button from accidental change to another mode of operation.
Automatic calendar
Once set, the automatic calendar always displays the correct date.
Sapphire crystal
Artificially manufactured glass with the hightest hardness and scratch resistance
Resin case
Resin band
Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties.
Water resistance classification (20 bar)
Perfect for free diving without scuba gear: the watch is water resistant to 20 bar / 200 metres. The metres value does not relate to a diving depth but to the air pressure used in the course of the water resistance test. (ISO 22810)
Type of battery
approx. 48,4mm x 53,8mm x 17,3mm (H x W x D)
approx. 93 g
