Reference:16700

Gmt-Master → 16700

The 16700 is the last GMT-Master, which is exactly why it matters. It keeps the older GMT-Master operating logic while living well into the GMT-Master II era, which makes it the cleanest late option for a buyer who wants sapphire crystal and modern case refinement without stepping into the independent-hour-hand mechanics of the GMT-Master II.

At a glance the reference looks simple. In practice it carries the same kind of late-run tension that many long Rolex references do: the end date is not perfectly clean, and the lume transition is not told the same way by every source.

Core facts

Where it sits in the line

The 16700 is the final GMT-Master rather than the first GMT-Master II, and that distinction is the whole point of the watch.

• it follows the 16750
• it runs in parallel with GMT-Master II references
• it keeps the older GMT-Master hand logic instead of using the independent-hour system

The watch has a loyal following for exactly that reason. It is the late, sapphire-era way to stay on the original side of the family split.

Production outline

The broad production frame is easy enough to state, but the exact finish line is not clean.

• the Field Manual uses 1988-1998
• Monochrome and Sotheby’s extend the watch through 1999

The safest article line is that the reference belongs to the 1988-1999 transition zone at the end of the GMT-Master story, with the exact final year depending on source.

The watch stays steel-only in the current source set and is directly supported in two bezel branches.

• Pepsi
• black

Movement notes

Caliber 3175 is the final GMT-Master movement.

• linked local hour and 24-hour hand
• quick-set date
• late-generation five-digit reliability with the older GMT-Master operating feel

One important contradiction should stay visible. The Field Manual and Monochrome both treat the 16700 as the last classic linked-hand GMT-Master. Sotheby’s 2025 cheat sheet appears to overstate the watch as if it had the independent flying GMT hand associated with GMT-Master II references. The direct article should stay with the more conservative reading.

Late Pepsi 16700

Black-bezel 16700

The current source set supports a simple but real branch split.

Pepsi branch

The Pepsi side keeps the family’s default visual identity alive right to the end of the GMT-Master line.

Black branch

The black-bezel side is a real late-run branch with its own look and appeal, not an option-list footnote. The direct late black example in the package makes that clear.

Lume transition

This is the main unresolved dial issue.

• the Field Manual says tritium to about 1997, then Luminova in 1998
• Monochrome says the watch moved from tritium to Super-LumiNova in 1997 and skipped Luminova

That contradiction should stay in the article rather than being blurred away.

Case, bezel, crystal, and crown notes

Pepsi bezel close-up

The case is the familiar 40mm steel Oyster shape of the late five-digit period. Sapphire and a Cyclops crystal immediately separate the watch from the acrylic 16750 it replaces.

The bezel palette is cleaner than the later GMT-Master II references.

• Pepsi is directly supported
• black is directly supported

The Field Manual also adds one smaller detail that still matters: open 6/9 date wheels are said to run until about 1992, with closed-style date wheels following after that. It is not enough yet for a full date-wheel chronology, but it belongs in the note set.

Bracelets, end links, clasps, and packaging notes

The Field Manual gives the strongest current fitment map.

• Oyster 78360 with 501B or 593 end links
• Oyster 78790A with SEL
• Jubilee 62510H with 502B end links

The direct sale set mainly shows Oyster presentation, not because Jubilee is impossible, but because that is how the best current examples in the package survive.

Packaging is decent for a first pass. The late black example in particular gives the article box-and-papers support instead of leaving the section at pure abstraction.

Special branches

Pepsi

The last classic Pepsi GMT-Master, and one of the cleanest visual arguments for why some collectors stay with the 16700 rather than moving into GMT-Master II references.

Black bezel

A real late branch rather than a side-option footnote.

Historical market and auction record

The current market layer is modest but usable.

• one late Pepsi example anchors the final Pepsi side of the line
• one late black example anchors the black-bezel side and gives stronger packaging detail

This is enough for a first article pass, but a true auction-house 16700 lot would still make the market section much better.
