Jowissa Aqua-Chief Automatic Diver, 1973

Jowissa Aqua-Chief Automatic Diver from 1973 combines a black dial, red-accented rotating bezel and cushion-style case in a strong tool-watch design. The men's Swiss watch has large luminous markers, broad hands and date at 3 o'clock, with a 21-jewel full-rotor movement, domed acrylic crystal and black strap carrying red stitching and lining.

Large markers, Arabic numerals and Aqua-Chief text

The black dial combines large luminous hour markers with oversized Arabic numerals at 12, 6 and 9. Broad luminous hands and central seconds provide the time indications, with a date window at 3 o'clock. Jowissa 21 Jewels is signed below 12, while Aqua-Chief and Shockprotected 5 ATM Tested appear above 6. The inscriptions and luminous elements are retained as actual design details, without a present lume-output guarantee or current pressure-test claim.

Rotating bezel and aged insert

The rotating bezel has a black minute scale and a red countdown-style section. Its serrated edge adds grip and texture, framing the dial with the same black-and-red combination carried by the strap. Aging remains visible on the bezel insert.

Cushion-style case and scuba-engraved steel back

The broad cushion-style case of this diving watch has angular lugs and a prominent crown, with visible vintage wear on both case and crown. A domed acrylic crystal completes the substantial profile. The stainless steel back carries a scuba diver engraving and the markings Waterproof, Shockresistant, Automatic, Vacuum Tested, Stainless Steel Back and Swiss Made. Steel is established for the back, without a confirmed main-case substrate. The 5 ATM dial text and back markings do not establish present water resistance.

Full-rotor Swiss automatic movement

The Swiss movement has a full rotor and is marked Twenty One 21 Jewels, giving this watch the self-winding mechanical operation of automatic watches. Hours, minutes, central seconds and date form the useful indications. Its 21-jewel construction is confirmed, without an individual caliber number or additional movement statistics. This used Aqua-Chief is fully serviced, with the existing case, crown and bezel wear remaining part of its vintage condition.

Black and red strap with warranty

The black strap has red stitching and red lining that complement the red bezel section. It brings the broad case and black dial into a cohesive sporting presentation suitable for casual wear. The cushion form, rotating scale and prominent dial indications express the early-1970s skin-diver character described for this example. It comes with a 12-month warranty, without a claim that the strap or every watch component is original.
