The question many ask after viewing the 2013 Rolex GMT Master II (Reference: case: 116710BLNR, bracelet: 78200) in stainless steel is: why is the Cerachrom bezel in blue and black?

The answer is simple; the blue represents the day while the black is for night and the colour codes become useful especially when the second time zone function with the blue hand indicator is being used.

The ceramic Cerachrom bezel insert was first rolled out by Rolex in 2005. What is noteworthy is that this is the first for the brand for a bicolour ceramic Cerachrom bezel (in blue and black).

 

 

Moreover, owners can expect the lustre to last as the brand states that the Cerachrom bezel is scrach-proof, highly corrosion-resistant and neither will the colours be affected by ultra-violet rays.

Did you know? Excessive ultra-violet (UV) radiation damages our skin’s cellular DNA and produces genetic mutations that can lead to skin cancer, states the Skin Cancer Foundation, adding that both the U.S. Department of Health and the World Health Organisation have identified UV as a proven human carcinogen.
