This Universal Geneve Polerouter ref. 20357-2 is a beautifully well-maintained piece of history, remaining 100% original.

If you don't know the name Gerald Genta, This is the same man responsible for designing some of the most iconic timepieces in existence including the Patek Philippe Nautilus and the Audemars Piguet Royal Oak On The C+T Blog What Is On My Wrist: The Universal Geneve Polerouter One of the most notable Universal Geneve watches of the post-war era was the Polerouter. Designed by Gerald Genta. Genta was recruited by Universal Genève SA, which was at the time one of the most recognized watch companies in both Europe and the U.S. mostly recognized for the company's chronograph models. After Universal Genève settled a patent dispute regarding the micro-rotor caliber of movement, the Polerouter was originally manufactured as the Polarouter in 1954, containing the Cal. 138SS bumper movement which was then quickly replaced with the Cal. 215 micro rotator movements which also resulted in a subtle name change from Polarouter to Polerouter. The Polerouter had taken on many variations within its first 15 years of production including Polerouter de luxe, Polerouter Genève, Polerouter Compact, Polerouter Super, Polerouter "NS", Polerouter III, Polerouter Jet, and the Polerouter Sub.

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.
