As for the inside of the watch, the difference is in the caliber which is the watch's movement, it's power source.
QUARTZ MOVEMENTA quartz watch uses a quartz movement which is powered by a watch battery and a quartz crystal.
Remember: Despite these 7 differences in appearance, these are two very different watches.
Built on 5 jewels, the movement offers Ronda’s power saving system.
Activated by pulling out stem, the system reduces power consumption of the movement by approximately 70 percent, significantly increasing the battery’s life span when the watch is not in use during (say, during the winter.) As far as I understand, this particular movement is slightly modified: the large date aperture has been moved from 12 o’clock to 6 o’clock position leaving enough space for the oversized “12” Arabic numeral.
