This term refers to a specific aesthetic execution applied to a luxury timepiece, combining two distinct precious metals or materials within its construction. For example, a watch might feature a stainless steel case coupled with a fluted gold bezel. This bi-metallic approach delivers a visually contrasting design element.
The use of contrasting materials enhances visual interest and provides a subtle differentiation from single-material constructions. Historically, the incorporation of these two-tone elements signified a level of sophistication and complexity in manufacturing, thereby elevating the perceived value and desirability of the item. This approach allows for versatile styling, often complementing a wider range of wardrobe choices and personal aesthetics.
