This replica GMT-Master 16720 black dial represents the final generation of the original GMT-Master line before Rolex transitioned entirely to the GMT-Master II. The 16720 shares the 40mm Oyster case proportions familiar across the range but uses an older-style aluminum bezel insert rather than ceramic. That distinction matters because the aluminum surface develops a gradual patina over time, giving the watch a character that newer references deliberately avoid. The black dial keeps things straightforward with luminous hour markers and a triangle at twelve, paired with a 24-hour hand for tracking a second time zone.

Technical Overview

• Case diameter: 40mm
• Bezel: aluminum bi-directional 24-hour scale
• Dial color: black with luminous indices
• Crystal: sapphire with date magnification
• Bracelet: Oyster with folding clasp
• Movement: automatic GMT
• Functions: dual time zone, date at 3 o’clock

The 16720 was produced from 1988 to 1999, bridging the gap between the acrylic-crystal era and the sapphire-equipped models that followed. Its slimmer case profile compared to current GMT-Master II references gives it a distinctly vintage proportion on the wrist.

Inside the Movement

Where the modern GMT-Master II features an independently adjustable local hour hand, the 16720 relies on an older GMT caliber where the 24-hour hand is fixed to the main timekeeping gear train. Adjusting the second time zone means rotating the bezel rather than jumping the hour hand. That mechanical difference defines the wearing experience and appeals to those who prefer the classic operational feel. Compare this against the green-dial 116718GSO to see how the series evolved across generations. Both sit within the broader GMT-Master lineup, yet the 16720 occupies a distinct vintage niche.

What Sets It Apart

Collectors gravitate toward the 16720 because it captures an era when GMT-Masters were issued to airline pilots as functional tools. The aluminum bezel, drilled lug holes, and thinner case profile separate it visually from anything in the current catalog. On the wrist, the 40mm case sits closer due to shorter lug-to-lug measurements. For those exploring vintage-inspired options, this replica GMT-Master 16720 black delivers that transitional-era aesthetic without the premium attached to original examples.
