Inclined surfaces and through holes direct light to a concealed solar cell, improving timepiece power generation while preserving a luxurious appearance.
Periodic clock-controlled winding reduces barrel wear while preserving power for a sympathetic watch assembly.
A cavity-mounted, coaxial indicator layout avoids stacked display parts to fit traditional hand displays into ultra-thin mechanical timepieces.
Cover-opening or capacitance detection triggers lock pulses only during tactile reading, limiting hand deviation and power use.
A support plate cut-out reveals an internal timepiece component while the sub-dial ring keeps its indicators easy to confirm.
Multiple moving indicators distinguish lunar and solar eclipses in mechanical or electromechanical horological movements for easier reading.
A processor moves the timekeeping hand to an evacuation position while a second display preserves time visibility and improves solar charging.
A pivoting date-correction rocker disengages during midnight changes, helping prevent date-drive arm breakage and unwanted date movement.
Detachable scale parts match racing distances to reduce watch-face clutter and improve average-speed readability across speed ranges.
A satellite toothed member on the month cam manages leap-year timing while reducing calendar thickness and assembly indexing.
Two-stage milling breaks down yttria-doped zirconia before phosphor mixing, limiting degradation and preserving glow in timepiece ceramics.
Multiple movable indicators distinguish lunar, solar, total, partial, and annular eclipses while improving readability in a clockwork display.
Bulky extra gear trains are replaced by one differential unit that keeps civil and true time minute hands concentric.
A rotating locking lever blocks the second timepiece corrector, preventing simultaneous wheel engagement and correction-wheel tooth damage.
A transient detector current strengthens hand-position signals before steady state, improving accuracy while reducing timepiece power use.
A rotating lunar model and FIFOP project an angle-independent phase image, preserving lunar appearance while simplifying the optical display.
