Important facts
The Omega Speedmaster Calibre 321 311.30.40.30.01.001 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 case of this watch is made out of stainless steel which is a strong and durable material, therefore being resistant to scratches, dents, and general wear and tear. Steel is also highly resistant to corrosion and rust, but is also a hypoallergenic material, which means that it is less likely to cause skin irritation or allergic reactions. Let's not forget the versatility of steel, which makes this watch pair well with several different attires.
This timepiece 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 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 useful complications.
