One of the most popular materials recently is natural stone. Watches with stone dials made from this material have become much more common than before. The minerals used for stone dials can be described as a record of nature, Created over millions or even billions of years through heat, Pressure and chemical reactions during geological activity.

Piaget began as a movement manufacturer and expanded into watchmaking, Jewelry and jewelry watches. The reason it is considered a pioneer of modern stone dials is because it has systematically used ornamental stones since the 1960s. While this is related to jewelry, The concept is slightly different. Ornamental stones are decorative natural stones that utilize their color, Pattern or texture and, Due to these characteristics, Have mainly been used for dials. This is a different approach from jewelry, Which is set to utilize brilliance and sparkle.

The materials for ornamental stone dials (hereafter stone dials) generally include rocks, Minerals or semi-minerals, Natural glass and meteorites.

They must be processed extremely thin. Although the standard varies by brand, They are usually cut to a thickness of 0.3 to 0.5mm. If processed thicker, They cannot be fitted into cases designed for regular dials or require a dedicated case design. They are also prone to breakage during processing and the nature and grain of the material varies greatly depending on the stone. Therefore, They cannot be processed using the same method. To highlight the color, Pattern and texture that determine the uniqueness of a stone dial, Careful consideration must be given to which part to cut and at what angle. For this reason, Only certain parts of the raw stone may be usable. Above all, Sourcing is difficult. Some meteorites or rocks are affected by the production volume of the origin or international circumstances. In this way, the rarity of the material and the high level of craftsmanship required combine to complete a stone dial. This is why stone dials are so highly valued.

This year, Piaget introduced a number of stone dial watches. They showcased a wide variety befitting their reputation as the originator of stone dials. Among them, The Andy Warhol watch ‘Collage’ Limited Edition, Created in collaboration with the Andy Warhol Foundation, Stands out the most. This watch was inspired by the Polaroid collage self-portrait created by the pop art master Andy Warhol in 1986. Instead of reproducing the original, It abstractly interprets the colors and composition in yellow, Pink, Green and black. Four panels made from yellow serpentine, Pink opal, Green chrysoprase and onyx stones are joined together using marquetry. Direct motifs such as the banana or Campbell’s soup can, Which symbolize Warhol, Are omitted and the mood of the work is conveyed through color and material. The technique of precisely cutting and joining natural stones with different textures and colors into a single dial requires a much higher level of craftsmanship than ordinary stone dials. The result demonstrates a level of mastery befitting the original pioneer.
