Catalogue description

Dealer description — Craft & Tailored

Hamilton was founded in Lancaster, Pennsylvania in 1882 and boasts a long and impressive history of breakthroughs in design and technology. While probably best known for their military associations and fantastic field watches, they've put out some really remarkable—and sometimes incredibly unique—outliers as well. Case in point, this extremely '70s day-date. The chunky, shield-shaped case, red and black dial, and quirky day-date setup all come together perfectly to offer a very unique—and uniquely affordable—time capsule. SPECS Stock # HTNDD8280013-2 Brand Hamilton Style Automatic Day-Date Model 825001-3 Serial N/A Size Men's Material Stainless Steel Dial Matte Black / Red Millimeters 37 Strap 2pc Handmade Leather Strap CASE & BRACELET The crisp, cushion-shaped tonneau case was recently polished to exhibit factory-like sunburst finishing with crisp edges. The case exhibits almost no signs of previous use. It comes with its original Hamilton crown and the case back retains its orignal factory markings and finishing. The watch is supplied on a handmade 2pc leather strap. DIAL & HANDS The original matte black dial is perfect and features chunky silver hour markers separated by bright red rectangles for a pop of color, and complemented by the cigarette-style hour and minute hands. The lume on the dial and hands has aged to a matching cream color and exhibit no degradation under UV light inspection. ACCESSORIES None. The watch is running, 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

Calendar, moon-phase and perpetual calendar watches

Calendar complications range from a simple date to the perpetual calendar, which automatically allows for months of different lengths and leap years until 2100. Pocket watches with perpetual calendars were made in the eighteenth and nineteenth centuries; Patek Philippe made the first perpetual calendar wristwatch in 1925, and series production followed in 1941. The annual calendar (Patek Philippe, 1996) needs correction only once a year.

Moon-phase displays use a disc with two moons and 59 teeth advanced daily, approximating the 29.5-day lunation; more precise trains reduce the error to one day in over a century.

What to look for

  • Apertures or subsidiary dials for day, date, month and leap year.
  • Moon disc under a 'bosom' shaped aperture.
  • Recessed correctors on the case band for setting the calendar.

Dating clues

  • Triple-date wristwatches: popular c. 1940–1955.
  • Perpetual calendar wristwatches: from 1925 (unique) and 1941 (series).
