The Spring Drive uses a conventional mainspring [3] and barrel [4] along with automatic and/or stem winding to store energy, just as in a mechanical watch. [3] However, the escapement and balance wheel in mechanical watches is replaced by Seiko's Tri-synchro Regulator system, a phase-locked loop wherein a rotor, which Seiko refers to as a "glide wheel", is powered by the mainspring barrel via ...
Any escapement with sliding friction will need lubrication, but as this deteriorates the friction will increase, and, perhaps, insufficient power will be transferred to the timing device. If the timing device is a pendulum, the increased frictional forces will decrease the Q factor, increasing the resonance band, and decreasing its precision.

Seiko SNK381 with 7S26-01V0 movement. In 1968, Seiko introduced three ten beat (ten ticks per second) calibers, the automatic caliber 61GS, the manual winding 45GS [46] and 19GS [47] for women's watch. The 61GS was Japan's first automatic ten beat watch, and it was the most accurate mechanical watch due to the high beat calibers. [48]
