Jewel Holes, Endstones, Roller Pins & Pallet Stones

Precision Components: Watch Jewel Holes & Pallet Stones

The heartbeat of a mechanical timepiece relies on more than just springs and gears; it depends on the reduction of friction at the most critical points of contact. Our professional-grade Jewel Holes and Pallet Stones are engineered for watchmakers and restorers who refuse to compromise on chronometric performance.

Whether you are performing a complete movement overhaul or replacing a chipped stone, these components provide the hardness and polished surfaces necessary for long-term reliability.

The Foundations of Low Friction

Jewel Holes (Pivot Rubies): Crafted primarily from high-grade synthetic sapphire or ruby, these jewels serve as the "bearings" for the gear train pivots. They minimize wear and ensure that energy transfer remains consistent across the entire power reserve.

Pallet Stones (Entry & Exit): The literal "locking" and "impulse" mechanism of the escapement. Our pallet stones feature precision-ground faces to ensure a crisp release of the escape wheel, directly impacting the watch’s amplitude and beat error.
