Catalogue description

Dealer description — Bulang & Sons

A beautifully preserved Long E GMT-Master with a strong, full case, warm tritium patina and an exceptionally complete set of original German paperwork. There is something very special about finding a vintage Rolex where both the watch and its history have been so beautifully preserved. This GMT-Master is a wonderful example, combining the character of an early matte-dial reference 1675 with a remarkable collection of original documents and accessories that have stayed together for more than half a century. The stainless steel case is particularly appealing, retaining plenty of volume, strong lug profiles and beautifully defined facets that are still clearly visible. These are exactly the details we love to see on a vintage sports Rolex. The watch has a wonderful presence on the wrist, especially with its domed acrylic crystal without the familiar Cyclops magnifier. This Tropic 38-style crystal gives the GMT-Master a cleaner, more open appearance and adds to its unmistakable tool-watch character. The matte black Mk1 'Long E' dial is another highlight, with its distinctive early Rolex typography and beautifully aged cream-coloured tritium hour markers. The hands have developed a complementary warm tone, creating a pleasing and harmonious appearance. Together with the bright red and blue Pepsi bezel, the watch has that wonderful contrast between vintage warmth and colourful sporting character. The blue-backed bezel insert is a later service replacement, something we are happy to mention as part of the watch's history. But what really sets this GMT-Master apart is the accompanying collection of original documentation. Alongside the original inner and outer Rolex boxes are both punched chronometer and guarantee papers, the seldom-seen original GMT-Master booklet, its large green document holder, a 1971 calendar, the original cigarette card and additional period literature. And perhaps our favourite detail of all: the original purchase invoice from Uhren Sonntag in Germany, documenting the sale in 1971 for just 632 Deutsche Mark. Finding a vintage GMT-Master with this much of its original history still intact is a real pleasure. Every piece adds another chapter to the story, making this much more than simply a beautiful watch. The watch is fitted with a folded-link Rolex Jubilee bracelet, reference 6251H, with 55 end links and an S3-stamped clasp. Its automatic movement has been fully serviced by an experienced professional watchmaker. We love this kind of vintage Rolex collecting. A great Long E dial, a beautifully preserved case and an almost complete collection of original paperwork and packaging. A wonderful GMT-Master to wear, enjoy and appreciate, with a story that makes ownership that little bit more special. Specifications: Rolex GMT-Master reference 1675, Mk1 'Long E' 40mm stainless steel case with full lugs and well-defined facets Serial 201xxxx, dating to 1969 Matte black Long E dial with warm cream-coloured tritium patina Tropic 38-style domed acrylic crystal without Cyclops magnifier Later service-replacement Pepsi bezel insert with blue back Folded Rolex Jubilee bracelet ref. 6251H, 55 end links, S3 clasp; original boxes, double-punched papers, GMT-Master booklet, calendar, cigarette card and 1971 German invoice Fully serviced by an experienced professional watchmaker Historical Context The Rolex GMT-Master was developed during the 1950s in collaboration with Pan American World Airways, providing international pilots with a practical way to track a second time zone. Introduced in 1959, the reference 1675 became one of the most important and longest-running models in GMT-Master history. During the late 1960s, Rolex transitioned from glossy gilt dials to matte black dials with white printing. Among the early matte variations, the Mk1 'Long E' is particularly appreciated by collectors for its distinctive typography, most notably the elongated middle stroke of the letter E in ROLEX. These small dial variations have become an important part of understanding and collecting vintage GMT-Master references. The reference 1675 retained the classic 40mm Oyster case, rotating 24-hour bezel and automatic GMT movement, establishing the design language that would influence generations of Rolex travel watches. Today, early matte-dial examples remain particularly appealing for their vintage character, historical significance and the subtle details that distinguish one generation from another.

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Atlas type guide

Military, pilot and travel watches

The wristwatch owes much of its adoption by men to warfare and aviation. Wristlets — small pocket watches soldered with lugs and worn on a strap — were used in colonial campaigns and became standard equipment in the First World War, with protective grilles over the crystal ('shrapnel guards'). Louis Cartier's Santos (1904), designed for the aviator Alberto Santos-Dumont, is often cited as an early purpose-made pilot's watch.

In the Second World War governments specified watches in detail: the German B-Uhr observation watches, the American A-11, and the British 'W.W.W.' (the 'Dirty Dozen' set of 1945). After the war, jet travel brought GMT and world-time watches, which show two or more time zones at once — Louis Cottier's world-time mechanism and the Rolex GMT-Master (1955) are examples.

What to look for

  • Military markings on the case back: broad arrow, issue numbers, 'W.W.W.', 'A.T.P.'
  • High-legibility black dials with luminous Arabic numerals; oversized crowns for gloved hands.
  • 24-hour hands and rotating 24-hour bezels or city rings on GMT/world-time watches.
  • Wire lugs on early wristlets converted from pocket watches.

Dating clues

  • Wire-lug wristlets: c. 1900–1925.
  • Military specifications of the Second World War: 1939–1945.
  • GMT and world-time wristwatches: mainly after 1950.
