Today, we will reveal the true strength of this latest upgraded version from the three dimensions of dial craftsmanship, movement performance, and wearing experience!

1. Subversive dial upgrade
This 15451 gray diamond watch uses a unique biscuit texture dial. The texture size has been carefully adjusted to make it more coordinated and three-dimensional than the earlier version. It is paired with a radial pattern design to present a very high visual hierarchy. The case size is 37 mm, which is perfect for wearers with small wrists and is suitable for both men and women. The overall design is mainly gray and inlaid with Swarovski rhinestones. It is low-key yet luxurious and suitable for various formal or casual occasions. In addition, users can also choose to upgrade to moissanite or real diamonds to further enhance the brilliance.
