Ball Watch pays tribute to its founder, Webster Clay Ball, with the Engineer M Marvelight model, the first watch equipped with a mechanism manufactured by the house itself, the BALL caliber RRM7309-C. The dial and hands of this watch are equipped with luminescent microgas tubes. The H3 gas is encapsulated in glass microtubes and the energy of the light is released when the H3 molecules hit the colored inner surface of these tubes. This luminescence can be prolonged over time for at least 25 years. Its black leather strap gives the watch and the person wearing it a classic and elegant touch.
