Tremblage– A decorative finishing technique that is hammered onto a dial or component. A tool called a burin leaves small indentations and cuts with each strike of the hammer, resulting in a finely detailed texture. The trick is to get all the indentations and cuts at more or less the same depth.
Stop-second mechanism– Features allows the the tourbillon to be stopped at will, enabling the watch to be set with precision.
Zero-reset function- When the crown is pulled, the seconds hand jumps to the zero position, it combines with the stop-seconds
mechanism, allows the watch to be set and restarted with one-second accuracy.
