Zenith G.F.J Calibre 135

The G.F.J. brings back to life the Caliber 135, the movement that garnered the most awards during the golden age of observatory chronometer competitions. This legendary caliber has been reengineered to integrate subtle yet meaningful improvements that enhance its reliability, precision, and overall performance without compromising its essence. The 39mm round case of this limited edition is crafted in a visually subdued, technically uncompromising metal: tantalum. Its three-part dark dial brings together black onyx, grey mother-of-pearl, and a guilloché pattern, elegantly accented with baguette-cut diamonds. Delivered with 3 different straps: a blue nubuck alligator leather strap, a black alligator leather strap and a grey calfskin leather strap. Exclusive limited edition of 20 pieces.
