Important facts

The Breitling Chronomat B01 42 RB0134101B1S1 has a screw-down crown which ensures a much better water resistance by providing a tighter seal between the crown and the case. This keeps moisture or dust from entering the watch case, which could otherwise cause damage to the movement. This also helps to prevent accidental adjustment of the time or date. The screw-down feature makes it more difficult for the crown to be accidentally turned, reducing the risk of incorrect timekeeping. Also, it is a reassuring feel to tighten the crown by screwing it down.

This watch has an automatic mechanical movement, which stores power in a mainspring, that is wound by an oscillating rotor while the watch is being worn. A mechanical watch movement is less accurate than a quartz one and requires regular servicing. It does not need a battery though and has a smoother sweeping seconds hand.

This timepiece 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.

The Chronomat B01 42 reference RB0134101B1S1 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.
