Machining a snail-profile groove on the barrel arbor expands spring storage volume without reducing shaft rigidity or attachment reliability.
- Watch Barrel Arbor Arc Recess Stress Reduction
Arc-shaped recess eliminates edge stress on watch barrel arbor hook, enabling smaller diameter and longer mainspring volume.
- Electroformed Mainspring With Integral Flange for Precision Positioning
An electroformed mainspring merges the flange and blade into one piece, eliminating welding scrap while maintaining precise flange alignment.
- Oxidized Titanium Barrel for Watch Mainspring Friction Reduction
Plasma electrolytic oxidation on a titanium barrel reduces frictional energy loss between the main spring and barrel, enhancing timepiece accuracy.
- Timepiece Barrel Arbor Core Integration for Power Reserve
A timepiece barrel uses a one-piece arbor and core sub-assembly to drive the ratchet while limiting drum axial shake.
