Our Standard
What We Look For
The vintage GMT-Master market rewards originality above all else. Condition, patina, and an untouched case are what separates a watch worth $12,000 from one worth $60,000. We evaluate every factor and pay accordingly.
A Watch Born From the Jet Age
From Pan Am Flight Decks to the World's Wrists
The GMT-Master was born from a contract, not a sketch. In 1954, Pan American World Airways approached Rolex with a specific problem: its pilots flying the new transatlantic routes were managing multiple time zones simultaneously — cockpit time, home time, destination time — with instruments that could only track one. Rolex's answer was the ref. 6542, the first GMT-Master: a 38mm Oyster with a red and blue two-tone bezel insert and a fourth hand that made one complete revolution every 24 hours. The "Pepsi" nickname — for the red and blue colors of the bezel — was not a marketing term. It was what collectors called it, quietly, decades later, when they understood what they had.
The ref. 6542 ran only from 1954 to 1959. Its bakelite bezel — which the FAA banned from cockpits as a fire hazard — was replaced by aluminum in the transition model, and by 1959 Rolex had introduced the ref. 1675, the watch that would define the GMT-Master for the next two decades. The 1675 was produced continuously from 1959 to 1980 — a 21-year run that generated every variation collectors now obsess over: gilt dials with their warm gold printing and pointed crown guards, the short-lived "fat font" dial printing, matte dials that replaced gilt around 1965, long chapter rings, short chapter rings, meters-first and feet-first depth ratings, tritium plots that have aged into every shade between white and deep cream, and bezel inserts in Pepsi blue/red, Root Beer brown/gold, and — by special order — all-black. Serial numbers for the 1675 run from approximately 545,000 to 6,100,000. Every hundred thousand serials tells a different collecting story.
In 1966, Rolex introduced the ref. 1675/3 — the "Root Beer" GMT-Master, with a brown and gold bezel insert that made it one of the most visually distinctive Rolex watches ever produced. The matching brown/root beer dial variant is rarer still and commands extraordinary premiums. The Root Beer was produced alongside the standard Pepsi 1675 through the end of the reference run. Gold versions — the ref. 1675/8 in yellow gold and the rare white gold variant — were produced in smaller numbers and are among the most sought-after GMT configurations of all.
By 1980, Rolex introduced the ref. 16750 — the "Transitional" GMT-Master, which bridged the gap between the 1675 era and the modern 16710. The 16750 introduced the quickset date function for the first time in the GMT line, retained the acrylic crystal of the 1675 era, and upgraded the movement to Cal. 3075 (28,800 vph). The 16710 followed in 1989 with a sapphire crystal and the full modern case, in Pepsi and Coke (black/red) bezel configurations, until 2007 when the GMT-Master II superseded it entirely. Each of these references has its own collecting logic — and we buy all of them.
What We Buy
Every Significant Vintage
GMT-Master Reference
From the 1954 bakelite-bezel ref. 6542 to the final ref. 16710 Coke. Pepsi, Root Beer, gilt, matte, tropical — every configuration purchased at the price the market actually pays for originality.
The watch we are most passionate about, full stop. The ref. 1675 Pepsi is 21 years of production across more variations than any other GMT-Master reference — gilt dials, matte dials, fat font, long chapter ring, meters-first, pointed crown guards, open crown guards, and dozens of dial/bezel/bracelet combinations. Early "Gilt" examples (c.1959–1965) with gold printing on glossy black dials and pointed crown guards command the highest premiums. "Fat Font" dials (c.1963–1965) — with wider, rounder letter-printing — are among the rarest and most coveted of all 1675 variants. We hold multiple examples in current inventory and pay the maximum the market offers.
★ Our Core SpecialtyAmong the most coveted dial variants in all of vintage GMT-Master collecting. The "Nipple Dial" gets its name from the applied round yellow gold hour markers — raised, circular, and gold-filled with luminescence — that distinguish these dials from the flat baton indices of the standard steel 1675. The nipple dial is found specifically on the two-tone Rolesor ref. 1675/3 and the yellow gold ref. 1675/8, and later on some examples of the 16753 and 16758. On the 1675/3, the nipple dial frequently pairs with the Root Beer (brown/gold) bezel insert, creating one of the most visually complete vintage GMT configurations in existence. A 1675/3 with an original brown nipple dial and a correct faded Root Beer bezel is a watch collectors search for over years. We evaluate every claimed nipple dial carefully — the applied round markers must be original and the dial correct for the reference.
★ Actively Purchased — Strong PremiumOne of the most visually distinctive watches Rolex has ever made. The 1675/3 "Root Beer" replaced the Pepsi's red/blue insert with a warm brown/gold bezel that gave the watch an entirely different character. Produced in Rolesor (steel/gold) as standard — with the matching two-tone bracelet — and in rare all-gold configurations. The Root Beer dial variant (brown/tropical dial with matching bezel) is exceptionally rare and commands dramatic premiums. A nipple dial Root Beer is among the rarest 1675 combinations in existence. A correct, unpolished Root Beer with original bezel is among the most desirable vintage Rolex configurations we encounter.
★ Actively PurchasedThe Coke 16710 is one of the signature vintage GMT configurations — a black/red bezel insert that gives the watch a bold, graphic character entirely different from the Pepsi's red and blue. Produced alongside the Pepsi 16710 for the full production run (1989–2007), the Coke is equally desirable to collectors and commands strong premiums in unpolished, original-bezel condition. The all-red insert 16710 — a special-order variant — is one of the rarest 16710 configurations. A faded Coke bezel where the red has shifted toward an orange-red is an original insert showing its age, which collectors appreciate. We buy all 16710 Coke examples in any condition.
★ Core SpecialtyThe first GMT-Master — produced for Pan Am and among the most historically significant Rolex sports watches of the 1950s. Two bezel insert phases: the original bakelite Pepsi insert (banned by the FAA; most examples have been replaced — original bakelite commands extraordinary premiums) and the later aluminum insert, introduced as a transition piece before the 1675. Cal. 1030 movement; 38mm case; no date; "thunderbird" or early pointed-crown-guard case. An original 6542 with intact bakelite bezel in any condition is a priority purchase for us. We also strongly value the aluminum-bezel 6542 in unpolished, original condition.
★ Highest PriorityThe rarest GMT-Master configurations of the vintage era. The 1675/8 in 18K yellow gold is produced in far smaller numbers than its steel counterpart and carries proportionally significant premiums. The white gold 1675/9 is rarer still — among the least-encountered GMT variants of the entire production run. The later 16758 in yellow gold (with sapphire crystal, 1983 onward) continues the gold GMT line. All gold GMT-Masters, in any condition, are priority purchases. Matching gold bracelets — original-length — add further value.
★ Priority PurchaseThe bridge between the 1675 era and the modern GMT line. The 16750 introduced the quickset date complication — the first in any GMT-Master — powered by Cal. 3075 (28,800 vph), and doubled water resistance to 100m. Crucially, it retained the acrylic crystal of the 1675 era, keeping its vintage aesthetic while improving the movement significantly. Produced in Pepsi (red/blue) and rarely Coke (black/red) bezel configurations. 40mm. Early 16750 examples with matte dials are the most desirable; from approximately 1986 onward, Rolex transitioned to glossy dials with applied white gold indices — matte-dial 16750s are rarer and command a premium. The 16750 is often undervalued relative to the 1675 it followed — we pay market price for correct, unpolished examples.
Actively PurchasedThe last Pepsi GMT-Master before the GMT-Master II superseded the line. The 16710 introduced the full modern case — closed lugs, sapphire crystal, 40mm — with the classic red/blue Pepsi bezel. Faded Pepsi inserts where the red has shifted toward pink or cream are original and prized by collectors. The all-red insert 16710 is among the rarest variants in the entire production run. Original, unpolished 16710 Pepsi examples with correct bracelets and original bezel inserts are purchased at strong premiums.

Why Glenn Bradford
The Glenn Bradford Difference
Glenn Bradford Fine Jewelry has been buying and selling investment-grade vintage watches from Southampton for more than forty years. The GMT-Master — and the ref. 1675 Pepsi specifically — is one of the watches closest to us. We are not generalists who occasionally encounter a Pepsi bezel; we are specialists who seek them, hold them, and transact them with collectors from around the world. When you bring us a 1675, you are speaking with someone who has handled the reference dozens of times, who knows what a correct chapter ring looks like, who can evaluate a bezel insert on sight, and who has a buyer community that pays the actual market for the finest examples.
Our expertise covers every dimension of the GMT-Master that determines value: the difference between a gilt dial and a matte dial and how condition within each category affects price; the chapter ring variants and depth rating configurations that command premiums; the bezel insert conditions that make or break a transaction; the bracelet codes and what a correct-length, unstretched rivet bracelet means to a serious collector. We evaluate all of these factors individually when we make an offer — not as a package discount.
The vintage Rolex market at the level we operate is a relationship business. We maintain direct contact with serious GMT-Master collectors internationally — people who are looking for exactly the watch you have, who will pay the maximum the market can bear, and who appreciate the discretion this community requires. Whether you are selling a single Pepsi 1675 or a collection assembled over decades, the first conversation is always free, always private, and never obligates you to sell.
Frequently Asked
Common Questions
Can I sell my GMT-Master if I'm not local to Southampton?+
Yes. We work with clients throughout the United States and internationally. Submit your piece through the form above with clear photographs of the case, dial, caseback, and any paperwork. We will provide a preliminary assessment promptly and can arrange fully insured shipping or a private appointment at our Southampton flagship boutique — whatever is most convenient for you.
How important is the bezel insert on a vintage GMT-Master?+
It is the first thing a serious collector looks at, and the most commonly replaced component on vintage GMT-Masters. An original insert — whether Pepsi, Root Beer, or Coke — that has aged naturally in place is worth significantly more than a replacement, even a period-correct one. Pepsi inserts that have faded from red toward pink or cream are not devalued by that change; the natural fade is evidence of originality and age, which collectors prize. We can assess the authenticity of a bezel insert from clear photographs. If you are uncertain whether your insert is original, contact us — it is something we evaluate on sight.
Do I need box and papers to sell my vintage GMT-Master?+
No. With vintage GMT-Masters, the watch itself is the primary determinant of value — not what came with it. An original, unpolished 1675 Pepsi with a correct-period bracelet and original bezel insert commands its full market value whether or not it has its box and papers. Documentation is an additive premium on top of what the watch already is. A correctly documented 1675 with a polished case will always be worth less than an unpolished example with no paperwork. We evaluate condition, originality, and bezel integrity first. Bring us the watch — whatever documentation you have is a bonus, not a prerequisite.
What makes one ref. 1675 worth more than another?+
In order of impact: (1) Case condition — unpolished, with sharp lug lines and original case geometry, commands the largest single premium. (2) Dial variant — gilt dial (especially fat font) commands more than matte; tropical patina on either is a major uplift. (3) Bezel insert — original vs. replacement, and the condition and color integrity of the original. (4) Bracelet — period-correct and unstretched, with a matching code for the serial range. (5) Serial/configuration coherence — everything should be consistent with the production period. We assess each factor individually and combine them into a complete picture.
