How does it light up?

The markers are light reactive.

How long does the charge last?

The battery is rated for 5 years.

How long does the glowing last for without requiring a light source to re-light up?

The luminescent material (made to our spec by the makers of SuperLuminova) is light reactive. After exposure to light, it will glow for hours. However, the output is proportional to amount, color and exposure to light. In gross terms: big white numbers exposed to sunlight for 2-3 minutes glow better than thin (let’s say) red numbers left in the dark (you’ll notice the second’s hand shine less than the number markers or watch hands for example). SL will be very bright right after exposure then gradually fade over time. The material absorbs light and slowly releases it.

What is the Japanese Movement in the watch?

The movement used in this watch is Miyota Japan OT45 movement with a 5-year battery.
