Catalogue description
Dealer description — Somlo Antiques
Produced between the years of 1961 and 1981, the reference 3445 was Patek Philippe’s first automatic wristwatch with a date function made in series, also featuring a water resistant style screw down case back. The calibre 27-460M (“M” for Monodate) was an evolution of Patek Philippe’s first automatic calibre, the 12-600AT, which was fitted to the legendary reference 2526. The calibre 27-460M had received several upgrades, including a Gyromax balance wheel, a ball bearing, and some additional jewels. Over the ensuing years, three series were made with the first fitted with an acrylic crystal, similar to the present watch, the 2nd series made during the late 1970s featuring a higher bezel to accommodate a sapphire crystal, and the 3rd series featuring a sapphire display back. The model was also made with integrated bracelets, and offered with dials in silver, champagne, blue, and later with grey dial with white Roman numerals.

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.
