Dials in natural stones — from the raw block to the polished disc

The creation of a dial in natural stone combines horological precision and mineral beauty. The stones used — lapis lazuli, jade, agate, charoite, turquoise, malachite, tiger's eye and iron tiger's eye — each bring their unique patterns and colors.

1. Stone Selection

Each rough block is assessed for its stability, the richness of its patterns, and the quality of its inclusions. The main stones:

2. Cutting into sheets

The stones are sawn into thin slabs using diamond blades. Each material requires a specific approach to avoid cracking and material loss.

3. Shaping and calibration

The plates are transformed into perfectly circular discs and calibrated to within a few tenths of a millimeter to fit watch movements. The properties of each stone require specific adjustments.

4. Fine polishing

Polishing reveals the natural colors, veins, and reflections of the stone. Lapis lazuli becomes a deep blue with its golden inclusions, malachite shines intensely, and tiger's eye reveals its famous chatoyancy.

5. Watch assembly

The polished disc is fixed to its support and integrated into the movement. Each dial is unique, with different veins and patterns depending on the stone.

6. Quality and durability

1. Visual inspection and detection of microcracks.
2. Thermal and mechanical compatibility tests.
3. Traceability of batches and origin of stones.

Each dial tells a unique mineral story, from the raw block to the polished disc, revealing time through the natural beauty of the stone.
