Catalogue description
Dealer description — S.Song Watches
The NYC based company Benrus produced the Sky Chief in the 1940’s and as the name suggests, it was made for the aviation industry. I must say, I do think that the Sky Chief presents great value in today's vintage market as it has many things going for it. The 35mm stainless steel case is muscular with a thick three-piece case. Featuring long bevels and lugs, the overall look on the wrist wears larger than its diameter suggests. Moving on to the dial, it has a beautiful black glossy gilt dial with enlarged Arabic numerals and thick syringe hands. Flip it over and you are greeted by the ever classic Valjoux 72 movement, a high-quality column wheel calibre that was used on the Rolex Daytona and Heuer Autavia. You might be wondering why a regular black dialled chronograph would be classified as a pilots watch and after researching online, it turns out it is all in the details. You will notice that in the minute register that there are hash marks at the 4/8/12 minute markers, which is highly unusual. Some have said that in the early days of aviation, a pilot would be required to take a measurement every four minutes as celestial navigation was used back then.
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.
