FAQS

How do I activate my watch after purchase?
Go to register and download the software for Mac or PC. After installing the software, connect the watch to your computer using a cable that came with the watch. Then the watch will be activated automatically and you will be able to use the installed software to adjust the watch settings.
How do I adjust the watch settings?
Download the software and connect the watch to your computer, then go to the settings menu – see our video tutorial.
How do I set the time without a computer?
Press and hold the button for 5 seconds until the digits start flashing – see our video tutorial.
What do I do if my watch runs fast or slow?
You need to calibrate the quartz crystal. First, connect the watch to the software, wait longer than 5 minutes, then turn the watch off and repeat the same cycle in 10-12 hours. If the problem returns, repeat the same procedure.
How long does it take to charge the watch?
Keep charging the watch until the flashing LED changes from red to blue or green. Do not keep the watch on charge for more than 16 hours!
How long is the battery life?
The rechargeable battery retains the charge for 7-10 days of daily use. You may need to replace it after a few years of use, as these batteries tend to degrade over time. Replacement batteries are available.
Is the case scratch-resistant?
The case is made of 316L stainless steel, which is used by all high-end watch brands. This type of steel is scratch-resistant and does not corrode, and you can also polish it when servicing your watch.
Is the crystal scratch-resistant?
The crystal has a scratch-resistant and anti-reflective coating. We also use heat-strengthened glass, which is virtually scratchproof and impact-resistant.
What do I do if my watch stopped working / broke down / the watch crystal cracked, etc.?
Please report your problem to ilya@gelfman.ch, and we will help you solve it.
Can I take my watch on a plane?
So far we haven't received any reports of people having problems getting through airport screening while wearing their IN-16 Nixie watch. All the internal components are visible to the security personnel, so it's easy to inspect.
