HBF Edition — Integrated Rubber Strap
The HBF iteration of the Spirit of Big Bang Sang Bleu represents a significant technical achievement in replicating Maxime Plescia-Büchi’s complex geometric architecture. This specific reference, characterized by its barrel-shaped multi-faceted structure, demands exacting CNC tolerances to properly align the alternating superimposed hexagons, rhombuses, and triangles. HBF has successfully mapped the relief effect and deep texture of the genuine article, offering a highly symmetrical three-dimensional case profile.
At the core of this replica is the Clone HUB 4700 automatic winding hollow movement. Unlike standard three-hand calibers, this movement is heavily modified to drive the signature geometric disc pointers that replace traditional hands. The skeletonized architecture is visible through the sapphire dial, maintaining the structural illusion of the genuine piece while delivering reliable timekeeping with an approximate 36-hour power reserve.
The 42mm case is constructed from a stainless steel and titanium core, finished with a rose gold PVD coating and extensive synthetic pavé crystal setting. Dial visibility is enhanced by a sapphire crystal with anti-reflective treatment, allowing clear views of the intricate disc mechanism and subtle warm copper-brown undertones within the gear train. The integration of the over-pressed rubber crown and signature H-shaped titanium screws completes the industrial aesthetic.
