Segmented clock face elements cut key presses and power use while combining time formats, astronomical objects, and light effects.
Two separate transmission lines let a sympathetic clock wind a watch efficiently and set time on demand while reducing barrel wear.
A recessed guide member supports a wearable wheel in radial and axial directions to cut friction, improve assembly precision, and resist impact.
A rotating bolt with a radial addendum limits wheel axial travel while simplifying removal, assembly, and clearance control.
Separate precious metal powders are sintered without mixing to form monolithic parts with localized composition and distinct mechanical properties.
A cam-driven rotating ring moves the watch crown or valve smoothly between radial positions while preserving secure operation and case aesthetics.
Color-matched compensation layers keep reverse dial decorations invisible without stimulus while preserving high-intensity visibility when activated.
A cam, rake, and drive-cam layout locks each gear pitch without a jumper, cutting energy use while keeping the display precise and secure.
A rotating control rod selects multiple timepiece correctors through one case opening, improving water resistance and preserving case aesthetics.
A translating crown head and elastic locking element keep coupled and uncoupled positions stable, reducing wear, size, and manipulation difficulty.
A structured emergent surface and layered light guide improve light distribution and extraction in luminescent watch hands.
A large rocker with month and year cams distinguishes 29/30-day months and 354/355-day years without a locking mechanism.
A display control section fast-forwards the sub-dial hour hand to the nearest zero position, cutting chronograph mode switching time.
Pre-detachment openings in watch fasteners localize fracture, enabling clean component release without extra surrounding space.
