Important facts

The Omega De Ville Ladymatic 425. 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 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 yellow gold) case, a combination of two different materials. Steel provides durability and affordability, while yellow gold offers elegance and prestige. This combination of materials creates a unique and attractive look for the watch, making it a popular choice among collectors. The two-tone case can be especially appealing to those who want the durability of steel, but also want the appearance of gold without the higher cost of a solid gold watch. Overall, the two-tone case provides a nice balance between durability, luxury, and style.

The De Ville Ladymatic reference 425. is a chronometer, certified by COSC, the Official Swiss Chronometer Testing Institute. The testing involves a series of measurements over a period of 15 days in different positions and temperatures to ensure the watch's accuracy.
