Catalogue description

Dealer description — Craft & Tailored

In 1963 two great chronographs were introduced. The Rolex Cosmograph Daytona and the Carrera line from Heuer. Both named after famous races and both developed for the automotive marketplace. There are far more Heuer Carrara chronograph variants than the Rolex Cosmograph range of watches, but both chronograph ranges are iconic and set the standard for what was to come from the major Swiss brands in the many years to follow. Rolex's main focus would be on waterproofness of their Cosmograph Daytona line while Heuer would ultimately focus on practicality and legibility. This 3147N is the second version of the Heuer Carrera with Date. There are a couple of things make the Heuer Dato 45 unique and different that captivates the attention of the collector and minimalist alike. First, as you will notice the layout of the dial is very uncommon and quite specific to the Heuer 3147 chronographs. Instead of the date being displayed in the typical and commonly seen at the 3 o'clock position, it is displayed at 9 o'clock position instead. The minute totalizer is large and displayed at the 3 oclock positions on the dial and records 45 minutes instead of the typical 30 minutes, this is also where the name Dato 45 comes from. Furthermore, there is no running seconds hand or subdial which makes the Carera Dato 45 quite unique and in alignment with Heuer's goal of keeping things legible and purposefully simple. The Dato 45's are somewhat hard to find especially the matte black dials as it seems that more Heuer Dato 45's were produced with the silver dial. Additionally this specific variant bears a "Swiss" only signature above the 6 o'clock position instead of the more commonly seen "T Swiss" which makes this specific example even more unique and worthy of collection!

CASE & BRACELET The case remains sharp and intact, showing factory geometry and finishing. The crown is signed Heuer and is most likely a later service replacement.

DIAL & HANDS The original matte black dial is clean and remains in a flawless condition free from any marks or scratches. The outer minute track like the dial is also in impeccable condition and remains perfect. The tritium lume dots on the dial have taken on a lovely creamy custard-like patina and remain fully intact when viewed under U.V. light. The original tritium hands are free from lume degradation and like the rest of the watch remain in perfect condition. ACCESSORIES None. The watch was serviced before our acquisition and is keeping time perfectly

Historical context

Modern Mechanical Horology (1945 – 1969)

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.

The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

Atlas type guide

Wristwatches

Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.

After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.

What to look for

  • The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
  • The calibre: its maker and number are often stamped under the dial or on the bridge.
  • Originality of dial, hands and crown — refinished ('redial') dials are common.
  • Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.

Dating clues

  • Wire-lug cases: before c. 1925.
  • Water-resistant screw-down cases: from 1926.
  • Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
