If he reused the original minute hand he appears to have done a great job in matching the colour. After exposing the dial to light, am I correct in assuming the lume on the minute hand continues to shine long after the hour hand stops glowing?
I assume he used superluminova or equivalent. When I had some hands refilled, I was given a choice by the watchmaker of using compound that was luminous or non-luminous.
Not sure of the composition only asked to match colour for aesthetics not looking to make it impossible to tell the difference. For now just enjoying it.
