GA1000-1A

This new G-Shock men's GA1000-1A model is the first in the G-Aviation lineup to be equipped with Twin Sensor capabilities, creating a watch that is perfectly matched to the needs of the modern aviator, both in terms of function and appearance. Pressing the button at the 9 o’clock position in any mode immediately goes to the Digital Compass Mode, and the button at the 8 o’clock position returns the watch to the mode it was in before the Digital Compass Mode. Continual direction readings can be taken for 20 seconds, during which the second hand points to north, a literal direction indicator is displayed in the upper display, and a direction angle value is displayed in the lower display. Bearing Memory lets you temporarily store and display a direction reading so you can use it as a reference as you take subsequent digital compass readings. Other features include temperature measurement, large numerals, and thick hands for easy reading. A coating on the tip of the second hand and minute markers reacts with the black light illumination of the watch for easy reading in the dark. Black resin band analog & digital with black/white/orange face.

What is Water Resistance?
Every watch is designed differently and the individual design of each watch determines how resistant to water pressure that watch is. You should always check the water resistance measure of a watch before using it, so you can decide when to wear it and when to take it off.

What is the ATM?
The ATM of a watch is short for Atmospheres and is a measure of the level of water pressure a watch is designed to withhold. A higher ATM means that a watch can withhold more water pressure, whilst a lower ATM mean that it was designed to withstand less pressure.

Metres: A Common Misconception
The ATM or water resistance of a watch can also be expressed as a number of metres, such as 10 metres. This does not mean that a watch can be taken 10 metres below sea level - although that is a common misconception. It is simply the number of times the pressure at sea level a watch can withstand without letting water in. For example, a watch with an ATM of 1 can withstand 10m of pressure, whilst a watch with an ATM of 5 can withstand 50m of pressure.

Using Your Watch in Water
The ATM of your watch will allow you to determine how and where you can use your watch. The ATM is usually engraved on the case-back of every watch. If you're having trouble finding it you may need to visit the watch manufacturer's website or contact them directly. You can use the chart below to guide you on using your watch in water. For example, if your watch has an ATM of 5, you can safely use it when you're washing hands and if it's raining outside, but you should not take it swimming or diving.

Swimming With Your Watch
The Watch Factory recommends purchasing a watch of at least 20ATM if you wish to wear your watch whilst swimming. Wearing a watch with a lower ATM whilst swimming may not always damage the watch, however we urge on the side of caution due to the delicate nature of watches.

Water Getting Into Your Watch
The internal mechanisms that keep your watch ticking are protected from water by the case, crown and seals that prevent water from getting in. Damage to any of these parts of your watch may void your watch's water resistance and cause moisture to get in. A common issue is when the crown has come loose and the seal has been damaged, which allows moisture to get in. If you believe that there is any damage to your watch, it is best to get it assessed by a watch maker who can check the water resistance is intact.
