The watch has a sapphire crystal with a double-sided anti-reflective layer, which reflects only 3% of incident light. The watch is thus perfectly legible even in direct sunlight. This model is mainly specific thanks to the GMT function, that shows the time in a different time zone. The fourth hand of the watch is used for this purpose.
