What is the difference between a chronograph and a chronometer?
Both terms come from Greek, but are used in watchmaking to denote two different types of watches: A chronograph is, as the name states, a time recorder - or more simply: a watch with a stop function for short-term measurements.
A chronometer is a watch which has received an official certificate from an official testing centre - such as the German Calibration Service (DKD) or the COSC in Switzerland - after 15-day precision tests in various locations and in different temperatures.
How does the Glashütte Original date-change system work?
Glashütte Original uses two different date-change systems: fast and slow date changes. In the slow version, the disc for the new day can "gradually" appear in the window as early as 2 hours before midnight, while the "jumping" date change sees the new day visible within a few minutes around the time of the date change.
For both mechanisms, avoid manually setting the date between 8pm and 2am. The automatic date-change function is working during this time.
Are my Glashütte Original's sapphire crystals scratch-proof?
Sapphire is one of the hardest materials on earth - second only to diamond. But even a "scratch-proof" sapphire crystal can display signs of wear if in contact with similarly hard materials - e.g. sand - or break upon heavy impact. We thus recommend always handling the watch with care.
What exactly is an anti-reflective coating?
The intense light refraction associated with sapphire crystals means reflections may affect your ability to read the dial, so we use fully non-reflecting sapphire crystals on the top side of our watches.
The chemical coating applied during this process is not quite as robust as the sapphire crystal itself. Over time, it may thus display minor wear or scratches. These are normal signs of wear and tear, which are not covered by our warranty.
Why do the hands and numbers on my Glashütte Original's dial light up in the dark?
The luminescent elements on your watch are made from the tried-and-tested "Super-LumiNova" material. Its luminous pigments store light and reproduce it again in the dark over extended periods. As such, you are guaranteed to have a visible dial even in poor lighting or complete darkness. Super-LumiNova is of course completely non-toxic and free from radioactive or environmentally harmful components.
What is the lifespan of the leather strap on my Glashütte Original?
Leather is a high-quality, organic material that has been used for millennia in clothing, jewellery and accessories. The types of leather used by us are made to last thanks to traditional tannic processes, and do not require any of the re-treatment needed for objects like leather shoes.
External factors such as perspiration, UV rays, hand creams or perfume can alter the leather's surface and structure, and cause discolouration or hardening. We recommend regularly cleaning the leather strap with a soft cloth. A mild soap solution can also be used to treat more intense stains.
