When constant force gets placed close to a mainspring, the mainspring’s unwinding power is easier to control. However, the torque becomes irregular, and the efficiency of the watch becomes uneven. If it’s placed closer to the balance, energy becomes more stable, but the torque is harder to control—a delicate trade-off,Replcia Rolex Day-Date Watches nearly impossible to have it both ways. Here a stable system was developed, placing the constant force as close to the balance as possible. This is the part where gravity comes into play with the addition of the tourbillon.
T0 Constant-force Tourbillon movement broken down into its minuscule parts
In general, a tourbillon carriage incorporates a balance, and an escapement mounted on a fourth wheel that rotates once per minute. The T0 stores torque from a gear coaxially arranged with the carriage in a constant force spring, and the energy of the unwinding spring gets used for rotating the carriage, including the balance in it.Rolex Day Date Replica Twin barrels are placed here in parallel, doubling the torque– the first movement in Seiko’s history of watchmaking to have two barrels placed parallel to release the stable constant force mechanism.
Additional improvements were added based on mechanical achievements from earlier innovations like the Calibre 9S65– the mainspring, wheel trains, escapement, balance, setting lever, and yoke. The 9SA5 provided a free-sprung balance with a regulator and high beat technology boasting 28,800 vibrations/hour. A prototype tested Omega replica watches revealed that gravity’s impact was reduced to one-tenth or less due to the tourbillon, and high-accuracy was maintained for 50 hours out of 72 hours due to the constant force. The combination of high frequency with a free-sprung balance would significantly increase the accuracy when wearing a watch – the T0 backs this up with a real movement.
