BT Factory Edition — Oysterflex Rubber Strap
The BT Factory execution of the reference 116589TBR ‘Eye of the Tiger’ represents an ambitious foray into high-jewelry horology. By combining a complex pavé diamond and black lacquer dial with a reliable clone caliber, this piece offers collectors a technically proficient alternative to one of Geneva’s most exclusive chronographs.
At its core beats the celebrated 4130 clone caliber, featuring a column wheel and vertical clutch architecture that mirrors the genuine mechanism. This allows for seamless chronograph engagement without the initial stutter found in horizontal clutch systems, delivering a power reserve of Approximately 36 hours.
The 40mm case is machined from 904L Oystersteel, featuring polished lugs and gem-set shoulders that frame the striking baguette-cut synthetic diamond bezel. While the use of stainless steel reduces the overall mass compared to the original 18k white gold, the visual proportions and Oysterflex integration remain highly accurate.
