Important facts

The Breitling Premier B09 Chronograph 40 RB0930371G1P1 has a sapphire crystal which provides a durable and clear viewing surface for the dial. This type of crystal is highly resistant to scratches and does not discolor over time. Sapphire is also resistant to most chemicals and less likely to shatter compared to other materials, making it a safer choice for the watch wearer. Thefore sapphire is a good choice for high-end wristwatches. It is of course an expensive option, compared to other materials, like plexiglass.

This watch has a chronograph complication, which is a function that allows the user to measure elapsed time, independent from the regular time. It is started and stopped by the press of a button, usually found on the side of the watch case. The elapsed time is displayed by hands on the sub-dials, and can be used to measure events like race times, cooking times, or similar where a precise measurement of elapsed time is needed. The chronograph is one of the most complex complications but also one of the most useful ones and arguably makes the watch look rather cool.
