BALL Engineer M NM2128C-S1C-BE Stainless Steel Automatic Blue Replica Watch

The Engineer M Marvelight is equipped with BALL’s first in-house movement and combines a sporty character with a classic watch design, all while enhancing BALL’s luminescent technology.

The manufacture caliber RRM7309-C achieves 80-hour power reserve by maintaining a 28,800vph high frequency. Every chronometer caliber is rigorously tested by Contrôle Officiel Suisse des Chronomètres for its quality and accuracy. The RRM7309-C is beautifully decorated, employing ribbing, perlage and spiral patterns, The RR logo, representing Official Railroad Standard, on the rotor pays homage to the brand’s heritage.

The Marvelight introduces a high degree of luminosity thanks to its luminescent micro gas tubes. This state-of-the-art Swiss technology used by the BALL Watch consists in encapsulating H₃ gas in glass micro tubes. Light energy is released when the H₃ molecules strike the internal colored surface of the tube, without requiring recharge from any outside light or energy source.

To reduce this risk of carrying external shocks right down into the caliber, the crown can be screwed-in tight to the case after the watch has been set. This model also features the Amortiser® patented anti-shock system for an even higher accuracy in case of external shocks.
