Now this is a cool one! As enthusiasts of the Rolex Milgauss know, the 116400GV stands out with its distinctive green sapphire crystal, a feature unique to this model. This Z-Blue dial, combined with the orange accents, offers a striking visual. The 40mm case, while substantial, maintains balanced proportions on most wrists, making it suitable for daily wear. 

Its Caliber 3131 movement, equipped with a paramagnetic blue Parachrom hairspring, ensures reliable timekeeping.  I've always found the lightning bolt seconds hand particularly captivating in daily use. Given its specific features, this reference holds a discreet collectibility among modern Rolex sports watches. Includes full set with whitetag and green hang tag.
