Catalogue description

Dealer description — Grey & Patina

The 6240 can be said to have birthed the screw down pusher Daytona lineup. Introduced in the early 60’s this is one of the least understood 4 digit Daytona references and one of the fewest ones produced with production numbers hovering around 2000. These early models are unique with individual characteristics that stick out to the seasoned Daytona collectors. The MK1 bezel is married to the earliest pushers, the MK0, and the first appearance of the nickel plated brass pushers found only on the 6240. The dial also sees a small change with a small floating “Daytona” name due to the separation between the first 2 lines of text. This specific 6240 has full lume plots with the exception of the 9 O’clock marker. The dial is a beautiful matte black with contrasting clean silver subdials. We feel this is an often overlooked Daytona reference while the big red models get a lot of the attention. Perhaps not everyone has caught on just yet… Dial: Black Small Floating Dial Insert: Mk1 Black bezel / Mk0 Pushers. Case: Excellent thick case Bracelet: Rolex Steel Oyster bracelet

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.
