Piaget

Piaget is a Swiss luxury watch and jewellery brand founded in 1874, known for ultra-thin movements, refined design, and high-end craftsmanship. The brand has created elegant dress watches, jewellery watches, and iconic models such as the Altiplano and Polo. Piaget watches are appreciated for their slim profiles, sophisticated finishing, and strong connection to both watchmaking and fine jewellery.

Wheel

Wheels are essential rotating components in a watch movement, used to transfer power, motion, and timing between different mechanisms. They appear throughout the gear train, winding system, setting system, calendar, chronograph, and automatic winding works. Wheels may be replaced when teeth, pivots, spokes, or friction surfaces are worn, bent, broken, corroded, or causing poor performance.
