Catalogue description

Dealer description — Analog/Shift

We love vintage watches for all sorts of reasons, chief among them being the stories they tell. Well, this one has a hell of a story. You’ve no doubt heard of the Reverso, Jaeger-LeCoultre’s famous reversible wristwatch, patented in the early 1930s. And if we were to show you a version of said wristwatch made by Hamilton — an American-founded company based halfway across the world — from the same decade you’d no doubt cry ‘foul.’ An unmarked Otis in good condition would be a special enough find — these watches had a relatively short production run. However, this one is even better: Dating to the 1930s, it’s beautifully inscribed on the back “To my dear husband on our twentieth anniversary with love Julia.” And if that sentiment weren’t enough, the reverse of the caseback features a gorgeous Masonic crest, executed in fine detail by someone who was clearly a master craftsperson. Housed in a 28mm 14K yellow gold-filled case, it features a beautiful, brushed silver-tone dial with applied stylized Arabic indices, an outer railroad minute track, a matching gold lance handset, and a sub-seconds register at 6:00. Powered by the manually wound Hamilton Caliber 980, it comes paired to a taupe suede leather strap with a gold plated pin buckle. Honestly, what can we say — this time capsule of a timepiece is the reason so many of us are so deeply fascinated by vintage watches. It’s the type of watch that deserves to live its second life with someone who will appreciate its charm and its story. If that’s you, then you know what to do!

Historical context

Golden Age of Mechanical Watchmaking (1900 – 1945)

The wristwatch displaces the pocket watch; waterproof cases, self-winding and grand complications.

The wristwatch overtook the pocket watch. Military use in the First World War, aviation, water-resistant cases (1926), automatic winding (1923–31), rectangular Art Deco designs and early chronographs and calendars defined the period.

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.
