Caliber 315 S QA LU

Self-Winding Movement With Date And Sweep Seconds

Description

Self-Winding Movement With Date And Sweep Seconds.
Caliber 315 has a self-winding mechanism powered by a central 21K. gold rotor which has a high degree of efficiency.
The difference between calibers 330 and 315 relates to the diameter of the date disc.
In caliber 330, it was slightly reduced to allow the date aperture of the Nautilus and Aquanaut models to be positioned closer to the center of the dial.
