Reference:16700
GMT-Master → 16700
The 16700 is the last GMT-Master, which is exactly why it matters. It keeps the older linked-hand GMT-Master operating logic while running 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 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.

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, runs in parallel with the GMT-Master II references that are already on sale, and keeps the older GMT-Master hand logic instead of adopting the independent-hour system. On a GMT-Master I the local hour hand and the 24-hour hand are linked, so setting one drags the other. That is the behaviour the 16700 preserves. 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.
A subset of collectors specifically chases the 16700 over the contemporary 16710. The reasoning is consistent across forum threads and the Monochrome retrospective. The linked-hand mechanism means the local hour hand jumps in one-hour steps when travellers set the date, which is the original travel logic that the GMT-Master was designed around. The 16710, as a GMT-Master II, trades that for an independent 24-hour hand aimed at tracking a second timezone from a fixed home base. Neither is objectively better. The 16700 is the one that still behaves the way the 1950s patent drawings behave, and for a certain kind of buyer that is the whole purchase.
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 Sotheby’s complete GMT-Master guide states plainly that the 16700 was produced for 20 years and that the line was retired in 1999. The Field Manual holds to 1998 in its reference table. Both numbers appear regularly in auction catalogues and dealer pages, and neither side has published a case number or archive extract that settles the question publicly. The safer article line is that the reference belongs to the 1988-1999 transition zone, with the final year dependent on which reference work the buyer trusts. Serial ranges from the late 1990s are consistent with either read, and most late examples in the surviving market are sold simply as “1998” or “1999” with an accompanying papers date.
The watch stays steel-only in the current source set and is directly supported in two bezel branches: Pepsi and black.
Movement notes
Caliber 3175 is the final GMT-Master movement. It keeps the linked local hour and 24-hour hand behavior that defines the GMT-Master I (as opposed to the independent hour hand of the GMT-Master II), adds the quickset date, and carries the late-generation five-digit reliability into a watch that still feels mechanically like an older GMT-Master.
One 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 article should stay with the more conservative reading.
Dial map
The current source set supports a simple but real branch split.
Pepsi branch
The Pepsi side keeps the family’s default red-and-blue 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 among surviving examples 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 entirely.
The gap is real and worth explaining. The Field Manual reads the late 16700 as following the broader Rolex rollout pattern, in which non-radioactive Luminova replaced tritium first and Super-LumiNova took over after roughly a year of overlap. Monochrome treats the 16700 as a watch whose transition happened late enough that it went straight to Super-LumiNova without the intermediate Luminova batch. Collectors who buy late tritium examples (T SWISS T dial foot) rarely have any dispute. The friction sits on the 1997-1998 boundary, where a SWISS or SWISS MADE dial foot may be read as Luminova by one reference and Super-LumiNova by another. The practical collector workaround is to treat the lume on a late non-tritium 16700 as “post-tritium luminescent” and let the dial foot printing and lume colour speak for themselves. Buyers who need certainty tend to look for early-1997 or earlier tritium dials, where both sources agree.
Case, bezel, crystal, and crown notes
The case is the familiar 40mm steel Oyster shape of the late five-digit period. Sapphire and a Cyclops lens over the date immediately separate the watch from the acrylic 16750 it replaces. The bezel palette is cleaner than on the later GMT-Master II references: Pepsi and black are both directly supported, and no other insert colour has meaningful source coverage.
The Field Manual adds one smaller detail that still matters. Open 6/9 date wheels, where the numerals on the date disc are drawn with open loops, are said to run until about 1992, with closed-style date wheels following after that. The detail is worth more than it first looks. A late-serial 16700 presenting an open-6/9 date wheel is a signal to examine the dial and hands more carefully, because service departments occasionally swapped date discs during movement work, and a wheel that does not line up with the expected production year is one of the easier authentication tells on an otherwise clean watch. The rule is not airtight. Overlap at the boundary is plausible, and no public Rolex service record nails the switchover to a month. The 1992 line works as a guideline for flagging, not as a verdict.
Bracelets, end links, clasps, and packaging notes
The Field Manual gives the strongest current fitment map. Period options include the Oyster 78360 with 501B or 593 end links, the later Oyster 78790A with solid end links, and the Jubilee 62510H with 502B end links. The surviving sale record mainly shows Oyster presentation, not because Jubilee is impossible, but because that is how the best current examples among surviving examples have survived.
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 Pepsi 16700 is 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
The black-bezel 16700 is 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.
