Catalogue description

Dealer description — Craft & Tailored

We present to you, the Tudor Date-Day. The less precious, equally functional, and absurdly funky counterpart to the Rolex Day-Date. The Tudor Date-Day was the economical offering of the iconic Rolex model, however, that didn't limit Tudor from being, well -- Tudor. Using the brand's spirited creativity, awesome concoctions of Tudor watches were created on this platform. The Date-Day was offered in a 36mm case size, similar to the Rolex Day-Date, as well as a 39mm known as the "Jumbo". The Tudor Date-Date was only produced in stainless steel and two-tone, unlike the Rolex Day-Date which is only produced in precious metals, and featured unique dial features and designs. The ref. 7020 Tudor Date-Day is a favorite reference amongst collectors for its enigma-like design. The ref. 7020 isn't really a dress watch and not exactly a sports watch either. This is mainly due in part to the combination of the sporty rotating bezel and enlarged case size with a more conservative dial design. This amalgamation of components makes for a fun all-rounder timepiece that is functional enough to daily wear and spark a conversation at your local watch get-together.

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

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.
