The invention relates to a clock movement which includes a balance and hairspring oscillator and an escapement engaging with the oscillator.
This simple comparison makes it possible to appreciate the improvement in energy consumption compared to a conventional balance & hairspring system.
This simple comparison makes it possible to appreciate the improvement in energy consumption compared to a conventional balance & hairspring system.
Its structure and its dimensions are calculated so as to minimize thermal drift of the balance wheel/hairspring assembly through first and second temperature coefficients of its spring rate.
Through the optimization of its barrel, escapement and hairspring, it offers no fewer than five full days, or 120 hours, of power reserve.
The invention also relates to a balance and spring assembly or to a timepiece including such a balance.
The invention relates to a method for adjusting the oscillation frequency of a balance and spring assembly.
The sprung balance: the soul of a mechanical watch
The barrel (4) and the balance spring (11) are coaxial with the central axis of the horological movement.
Minimum Requirements (for balance spring wristwatches) - Type I
Method for adjusting the frequency of a balance-spring assembly formed at random from an entire production of springs and balances.
This movement also has Omega silicon Si14 balance spring and free spring balance.
This movement also features Omega’s silicon Si14 balance spring and free-sprung balance.
It is fixed to the roller, under the balance-spring for which it serves to maintain the oscillations.
The manufacture Locle Zenith has unveiled a new oscillator.
The ISO 3159 standard gives the definition of a wrist chronometer with a sprung-balance oscillator.
A system of adjusting the balance and spring assembly, patented by Patek Philippe in 1949 and 1951.
The pendulum, the balance spring and then the quartz make it possible to multiply the precision of clocks.
The invention relates to a timepiece comprising a mechanism for improving the accuracy of mechanical time measuring instruments using a balance-spiral system.
