SPECS Stock # ZZHJA758 Brand Zodiac Style Hermetic Jet-Aeronaut Model 758 Serial 13XXXXX Size Men's Material Stainless Steel Dial Black Millimeters 34 Bracelet Single Pass NATO Strap CASE & BRACELET The Zodiac Hermetic features a 34-millimeter stainless steel case with fantastic bold lugs that amp up the watch's presence on the wrist. The Hermetic showcases a special snap-down case back that features an unusual water-resistant system, not unlike that found on its sibling model the Sea-Wolf. The watch comes accompanied by a colorful, matching single-pass NATO strap. DIAL & HANDS And now to the main event. The dial is a deep, ink-black, with a fantastic mix of typography and design. This Zodiac is a rare offering from the brand due to its utilization of a 24-hour dial. Jumping off the dial and marking the odd hours are bold and bright red markers tipped in aged radium plots. The thin index hands show their age but retain their radium, while the ever-thinning second's hand reaches out and sweeps the dial edge. No matter how often this watch is worn it is sure to bring out a smile. ACCESSORIES None. The watch is in perfect working condition, extended service history is unknown.

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.
