Important facts

The Breitling Navitimer B01 Chronograph 43 UB0121211F1P2 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 watch 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 timepiece has a two-tone (steel and rose gold) case, a combination of two different materials. Steel provides durability and affordability, while rose gold offers a warm, fashionable touch to the watch. This combination of materials creates a unique and attractive look for the watch, making it a popular choice for those who want both style and function. The two-tone case can be especially appealing to those who want the durability of steel, but also want the soft, romantic appearance of rose gold. Overall, the two-tone case provides a nice balance between durability, luxury, and style.

The Navitimer B01 Chronograph 43 reference UB0121211F1P2 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.
