Catalogue description

Dealer description — Craft & Tailored

Hamilton was founded in Lancaster, Pennsylvania in 1882 and initially specialized in producing pocket watches. The brand boasts a long and impressive history of breakthroughs in design and technology, and while probably best known for their military associations and fantastic field watches, they've put out some really remarkable outliers as well. Case in point, this incredible Dateline UFO. So named because of its disc-like, lug-free case shape, this is an otherwise incredibly classic piece with an aged silver dial, oversized silver hands and hour markers, and that classic Hamilton understated style. SPECS Stock # HAMDL640463 Brand Hamilton Style Dateline Automatic Model 64046-3 Serial N/A Size Men's Material Stainless Steel Dial Silver "Aged" Millimeters 38 Strap 2pc Black Leather Rally Strap CASE & BRACELET The wonderful ultra-round "UFO" case has been gently polished in the past and show light wear.

The large, rectangular hour markers are in beautiful condition and match the handset well, under UV light inspection the lume does exhibit degradation throughout the markers, however this has no affect on the aesthetic of the watch. The lume in the hands has aged to a light cream color and is in otherwise great condition. ACCESSORIES None. The watch is keeping time, but the service history is unknown. A movement service can be provided upon request.

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.
