Functions
PRW-2500T-7ER

Full-Auto Illuminator
Automatically deactivates the Auto EL backlight function when surrounding light is sufficient, and activates it under dim light or dark conditions.

Low-temperature resistant (-10 °C)
Even temperatures as low as -10 °C have no effect on this watch.

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.

Duplex LCD
Giving you a constant overview: Elements on the display are distinguished from one another using colour. This is achieved using different coloured layers placed on top of one another, allowing information to be displayed more clearly.

Digital-compass
A built-in direction sensor detecs the magnetic north.

10,000 m Altimeter
A pressure sensor detects changes in the air pressure and converts the result into an altitude up to 10,000 m.

Height Gain
The height gain sums all the meters you have climbed in a session, so that you can see at a glance the total ascent on a tour.

Altimeter data memory
Depending on the model, up to 40 sets of elevation data can be stored in the watch's data memory and re-accessed at any time. Each of these data sets consists of a measured altitude as well as the date and time. In addition to the individual altitudes, the maximum and minimum altitudes during a measurement are also stored.

Barometer (260 / 1.100 hPa)
A special sensor measures the air pressure (measuring range: 260/1100 hPa) and presents this on the display in the form of a symbol. This enables early detection of weather trends.

Thermometer (-10°C / +60°C)
A sensor measures the ambient temperature around the watch and displays it in °C (-10°C /+60°C).

Moon Phase Indicator
The moon phase indicator shows the current moon phase based to the earth

Tide indicator
Once the high tide time has been entered for a selected location, the watch can display the low and high tide phases at this location on any given date. This can be quite useful, for example, if you want to know the patterns of the tides at your destination in advance.

World time function
Displays the current time in major cities and specific areas around the world.

Accuracy
radio-controlled

Type of battery
CTL1616

Stopwatch function - 1/100 sec. - 24 hours
Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours.

Timer - 1/1 min. - 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 minute and up to 1 hour in advance.

Yacht timer without automatic repeat function
The perfect prerequisite to every regatta and yacht race: The countdown start time can be set within a period of 1 to 10 minutes, usually 5 minutes. An audible signal sounds once after every elapsed minute. For the last ten seconds before the start, the signal sounds every second.

5 daily alarms
The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments.

Button tones on/off
The button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated.

Automatic calendar with Date, Day and Month
Once set, the automatic calendar always displays the correct date.

12/24-hour timekeeping
Times can be displayed in either a 12-hour or 24-hour format.

Direction Bezel
This bezel can be used to determine approximate directions.

Mineral glass
The tough mineral glass resists scratching.

Resin case

Solid titanium band
Stylish look and lightweight properties set titanium apart. The high-quality material is resistant to corrosion and is gentle on the skin, making it ideal for allergy sufferers.

Safety Catch
Always reliable: This watch has a particularly secure safety catch, which helps prevent the strap from opening by mistake.

Battery level indicator
An indicator shows the current battery level.

Water resistance classification (20 bar)
Perfect for free diving without scuba gear: the watch is water resistant up to 20 bar according to ISO 22810.
