The HM4 Thunderbolt comes into the world from the child's fantasy and the man's tenacity.?Engine: HM4's engine was entirely designed and developed by MB&F over three years of intensive work with Laurent Besse and Beranger Bvlgari BB38SLDCH Men's watch Reynard of Les Artisans Horlogers.Each one of the 311 components were developed specifically for the Thunderbolt, no off-the-shelf mechanisms or parts were utilised whatsoever due to the extreme nature of their architecture.?
Two mainspring barrels connected in parallel provide 72 hours of one's, plus they transfer their ability towards the dual jet-turbine-like indication pods (one displaying the amount of time and minutes, the other the ability reserve) vertical gear trains.Visible through a shaped sapphire display panel on the top of the case, a unique Bvlgari BB38SLDCH streamlined cock supports the balance, its centre cut off to reveal as much of the oscillating wheel as possible and validating the "kinetic" in MB&F's "kinetic art". A thing of beauty rewards when viewed from different angles and the Thunderbolt is no exception.
Turning the machine over reveals a veritable panorama of meticulously finished micro engineering through the sapphire sections.In a playful trompe d'oeil, what at first glance seems to be a micro-rotor as MB&F's iconic battle-axe is actually a bridge.Indications: For a timepiece not developed specifically to tell the time, HM4 Bvlgari BB38SLDCH watch performs that role superbly.Actually, using its highly legible dials perpendicular towards the wearer's wrist, Horological Machine No4 might be described as an ideal pilot's or driver's watch.
