Replique IWC Ingenieur Constant-Force Tourbillon IW590001

This IWC Ingenieur Constant-Force Tourbillon 46mm IW590001.（Replique IWC Ingenieur） It ensures that the balance of the balance wheel vibration frequency is absolutely consistent, which can guarantee the absolute rate of travel time accuracy. First, the escapement is decoupled from the direct power transmission of the train wheel, and the power is temporarily stored in the gossamer and delivered to the escape wheel. Gossamer once every second tension, the tourbillon's second hand is also a second unit to jump forward. This mechanism ensures that at least 48 hours of travel time is absolutely balanced and accurate. After about 2 days, the constant power mode will be converted to normal mode. At this point, the second hand will jump every fifth of a second.

This precision timepiece integrates the patented constant power unit in the tourbillon, making the balance of the balance wheel almost constant, which can guarantee an extremely uniform travel rate of at least 48 hours. The 94800 base movement integrates the power of the two barrels to provide the greater torque required to drive a constant power tourbillon, as well as to provide energy for the moon phase profit and loss display module. Bimonthly profit and loss show so realistic, so that you can clearly see the moon on the subtle crater. The countdown is used to display the number of days from the next month. The power reserve display is located between the "4 o'clock" and "5 o'clock" positions, showing the remaining available power for the chain. The movement design inspired by the racing engine, through the transparent sapphire glass bottom of the table can be a glimpse of the internal gear meshing with the fascinating scene, reflecting the first-class performance engineering.https://www.montreabordable.co/
