The G-SHOCK with Bluetooth® v4.0 (power-saving Bluetooth® technology) offers battery-saving NFC technology at the touch of a button, all day long. The Bluetooth® v4.0 connection allows you to access a host of useful features and functions for your iPhone, such as incoming call and email alerts on your G-SHOCK, phone finder, link loss alert, automatic time adjustment, and much more.
All that is required for these and many other functions is a single coin battery with a battery life of two years, and everything is protected by the world-famous G-SHOCK shock resistance.
All this and much more make the G-SHOCK more sophisticated and robust than ever.
Incoming call alert
If your phone receives a call, the watch will beep or vibrate.
* With an iPhone, the caller information is not displayed.
Incoming mail alert
This function lets you know if your phone receives an email. This function is especially practical if you need to know straight away when you receive messages.
* An iPhone requires an email address to be registered with the special G-SHOCK+ app. This function does not support any SMS or text message accounts.
If you press a button on your watch, your smartphone emits a sound so that you immediately know where it is. Simply touch the watch to stop the sound.
Link loss alert
The G-SHOCK always vibrates if the connection between the watch and the iPhone is lost due to the distance being too great, environmental factors or any other reasons.
If you take off your watch and don't wear it for a while, it switches to energy-saving mode and the communication functions are switched off. A switch inside the watch allows it to detect as soon as it is moved again and it automatically reconnects with the phone, with no manual operation required.
The watch takes the time from your phone and updates its own settings accordingly. This function is extremely practical for business or holiday travellers who no longer have to worry about the correct time for the time zone that they are in, and no longer have to set it by hand either.
* The watch updates your time setting as soon as the time setting on the phone is updated. Please note that some telecommunication companies do not offer automatic time adjustment to the local time.
The hour, minute and second hands are controlled by different motors. These independently operated hand control systems have made it much easier to use analogue watches, as they allow highly precise multifunctional displays to be used, and reduce the amount of time spent changing the functions.
The new LSI processor technology makes G-SHOCK considerably easier to use thanks to a single electronic crown. The various functions are operated intuitively by rotating and pressing the electronic crown. Setting up various functions no longer requires you to use several buttons.
G-SHOCK Tough Solar technology is unique. Solar cells that are invisibly integrated into the watch face convert even weak light from fluorescent lighting into electrical energy that keeps charging the powerful battery independently and without wasting the earth's resources. Surplus energy is also stored in the battery so that the watch can operate at full capacity even during long periods of darkness. Even memory effect has been eliminated, as the battery does not lose its capacity.
For all G-SHOCK models with Tough Solar technology, changing the battery is therefore a thing of the past.
The exact time at all times! All radio-controlled G-SHOCKs have a tiny antenna that receives signals from around the world in order to ensure precise timekeeping. Once set to the local time zone, G-SHOCK always displays the exact local time.
The G-SHOCK Multi Band 6 technology receives time calibration signals from six radio towers around the world, which transmit the time defined by atomic clocks directly to the G-SHOCK. Transmitters of this kind can be found in Mainflingen (Germany), Anthorn (UK), Fort Collins (US) and Shangqiu (China). Japan has two of these transmitters; one in the Otakadoya Mountains in the North East and one in Hagane in the South West.
