What distinguishes it
Look beyond the reference.
The stored energy is electrical rather than a wound mainspring. The specified six-month duration assumes stopwatch use of one hour a day; exposure to light replenishes the charge.
For the enthusiast
A charge-level display helps explain why this movement can stop even though it is solar: it still has a finite energy store. Its fifth-second chronograph display describes timing resolution, not the crystal oscillator’s frequency or an accuracy guarantee.
