In celebration of the 20th anniversary of the Aquanaut's launch in 1997, the 5168G model is now available in a new "Jumbo" size of 42.2 millimeters. This men's watch has a masculine design, with an embossed dial that subtly graduates from black to night blue and a delicately satin-finished bezel that exudes casual elegance.

The watch features a self-winding caliber 26-330 S C movement, a date display in an aperture, and a sweep seconds hand. The blue embossed dial has gold applied numerals with a luminescent coating, making it easy to read in low-light conditions. The white gold case is water-resistant to 120 meters and has a screw-down crown and sapphire crystal case back. It measures 42.2 mm in diameter from 10-4 o'clock and is 8.25 mm in height. The "tropical" composite strap is midnight blue and has an Aquanaut fold-over clasp.
