The [[Reference:16758|16758]] is the solid-gold GMT-Master in the [[Reference:16750|16750]] generation. It keeps the older GMT-Master hand logic, adds quick-set date through caliber 3075, and moves the gold GMT line into the five-digit era without yet becoming a GMT-Master II. The watch still looks back toward the 1675/8, but it already points toward the [[Reference:16718|16718]].

=== Early matte phase ===

VRFM treats the earliest [[Reference:16758|16758]] watches as visually closest to the outgoing 1675/8: matte dials, the older visual warmth, and the strongest continuity with the late vintage gold line.

VRFM treats the earliest [[Reference:16758|16758]] watches as visually closest to the outgoing 1675/8: matte dials, the older visual warmth, and the strongest continuity with the late vintage gold line. The early matte phase sits at the front of the run, from around 1979 through the first years of production, which places it in parallel with the early matte [[Reference:16750|16750]] watches. The dial surface reads flat rather than glossy, with brown or black printed text and raised nipple indexes carrying the older visual recipe forward.

=== Middle glossy sunburst phase ===

Glossy sunburst dials then take over through the middle of the run. This is where the reference starts to look more overtly 1980s while still keeping the old GMT-Master operating feel.

Glossy sunburst dials then take over through the middle of the run. This is where the reference starts to look more overtly 1980s while still keeping the old GMT-Master operating feel. Brown sunburst dials from this phase show a radial grain that catches light in concentric rings, and black sunburst dials do the same with less color shift. The visual feel shifts from the warm, textured matte look of the 1675/8 to a more reflective, decade-appropriate finish, though the case, bezel, and movement stay identical. VRFM places this phase through the middle of the 1980s without a named cutoff, which fits the 1982 and 1987 watches in the corpus sitting on either side of the sunburst window.

=== Late gold-surround phase ===

Later dials add the familiar gold surrounds around the lume plots. This is the phase that most clearly points toward the later [[Reference:16718|16718]].

Later dials add the familiar gold surrounds around the lume plots. This is the phase that most clearly points toward the later [[Reference:16718|16718]]. A gold-surround dial keeps the applied lume plot but adds a polished gold ring around each one, which changes the dial reflection pattern without altering the underlying layout. The visual effect is a closer match to the neo-vintage gold GMT-Master II watches that follow, and it is the strongest late-run signal on a surviving [[Reference:16758|16758]] dial.

The current source set supports two main branch colors and a three-step dial phase story.

The reference uses a solid yellow-gold Oyster case with crown guards and an aluminum 24-hour insert. The bezel behavior also matters. VRFM argues that the [[Reference:16758|16758]] keeps the older friction-fit, non-clicking bezel, with the clicking bezel arriving only on the later [[Reference:16718|16718]].

The physical difference between the two bezel formats is straightforward. A friction-fit bezel rotates freely on a smooth spring ring, which lets the insert turn in either direction without any audible or tactile stop. A collector turning a [[Reference:16758|16758]] bezel feels a steady, unnotched rotation with no internal engagement, which is the same behavior that defines the earlier [[Reference:1675|1675]] and 1675/8 bezel. A clicking bezel, by contrast, sits on a toothed click-spring mechanism that indexes the bezel in discrete stops, most often 120 positions per full rotation. The [[Reference:16718|16718]] uses the clicking format, and every rotation produces a sequence of clicks along with a defined feel at each stop. The change is mechanical rather than cosmetic, and a surviving [[Reference:16758|16758]] with unmodified bezel hardware should rotate smoothly rather than click.

The crystal story is the main unresolved hardware point.

Sapphire remains the stronger reading, but the contradiction should be presented directly rather than blurred away. Monochrome and VRFM both frame the [[Reference:16758|16758]] as the reference where the gold GMT line moves to sapphire, which fits the later production date and the [[Reference:16718|16718]] trajectory. The Bob’s brown 1982 listing describing acrylic can be read in two ways: either the earliest production watches genuinely kept the acrylic crystal from the 1675/8 platform while the case and movement updated first, or the specific surviving watch has a replacement acrylic crystal from a service. Both readings are live in the corpus. The cleanest position is that late-run [[Reference:16758|16758]] examples are sapphire and early-run examples may be either, with the changeover not cleanly documented in the current source set.

Line 155:

The black branch matters because it breaks the habit of reducing every gold GMT to Root Beer.

The production balance between the two branches leans toward brown. The gold-GMT lineage built its identity around the warm brown-and-gold look first documented on the 1675/8, and the [[Reference:16758|16758]] inherited that market expectation when it launched in 1979. Retail buyers ordering a gold GMT in the early 1980s were most often reaching for the Root Beer visual continuation, which produced more brown dials in period. Black dials existed as a parallel factory option across the run, as the Field Manual states, but they appealed to a narrower buyer profile: someone who wanted a gold GMT without the tropical color story. The surviving market reflects that imbalance, and the brown branch remains the more commonly encountered format at auction and dealer level. The black branch is not rare in the strict sense, but it is less common, and late-run black sunburst and gold-surround examples have attracted renewed collector attention as the broader gold-sports-watch market has matured.
