Cutting Edge: How Signature Gemstone Cuts Are Transforming Timepieces

Jewellery houses are increasingly bringing their signature gemstone cuts into watchmaking, applying lapidary expertise to dials, cases and even movements. From Tiffany & Co. to TAG Heuer, brands are using distinctive cuts and facet patterns not as decoration alone, but as central elements that shape the design and identity of their timepieces.

The use of these signature cuts in horology reflects a wider move within high watchmaking to borrow directly from the language of jewellery rather than simply embellish with stones. Cuts once reserved for engagement rings or tiaras are now shaping sapphire crystals, defining case silhouettes and even dictating the architecture of movements. This convergence underscores how closely the two métiers are now aligned, with brands drawing on their heritage in lapidary craft to bring new depth and distinction to watch design. The result is a diverse set of interpretations, with several brands now leading the way.
