Zenith Super Sub Sea Ref. A3736

Partially verified

This 1970 Zenith Super Sub Sea, reference A3736, is a diver chronograph featuring a 41mm stainless steel case. It is powered by the 17-jewel 146-HP manual-wind movement, noted as the final manual-wind caliber developed by Zenith-Movado before the introduction of the automatic El Primero. The watch presents a matte black "reverse-panda" dial with silver sub-dials, paired with a distinct orange internal rotating bezel. The case is equipped with original signed crowns and pushers, accompanied by a Zenith "Gay-Freres" ladder flip-lock bracelet featuring original ZG end links. The auction description reports the case has undergone light polishing while retaining its original angles, and the internal bezel functions correctly with an intact tritium arrow at the 12 o'clock position.

Object description

Case and Bracelet

The watch is housed in a 41mm stainless steel case that has been lightly polished while maintaining its primary angles. The assembly includes two pushers and a Zenith-signed winding crown, all described as original to the timepiece. An internal rotating bezel, featuring an orange background and a tritium arrow marker at the 12 o'clock position, remains functional.

The watch is fitted with a Zenith "Gay-Freres" ladder-link bracelet, a component identified as original to the watch. This bracelet includes the specific ZG-stamped end links and is reported to be in excellent condition, exhibiting minimal stretch in the links.

Evidence for this section
  • “The lightly polished case retains strong angles with light signs of use.”
  • “The inner rotating bezel retains its tritium arrow at the 12 o'clock position, remaining in perfect condition and functions flawlessly.”
  • “The original and elusive Zenith "Gay-Freres" ladder flip-lock bracelet remains in excellent condition with almost no stretch and retains its original ZG end links.”

Dial and Hands

The timepiece features a matte black dial in a "reverse-panda" configuration, characterized by contrasting silver-toned sub-dials. The dial is printed with "Zenith" and a star logo below the 12 o'clock position. The hour and minute hands are paired with a bright orange "lollipop" chronograph seconds hand.

The dial indices and hands have developed a uniform yellow patina consistent with aging. According to the auction description, the dial and hands show no signs of degradation or loss of luminous material upon inspection under U.V. light.

Evidence for this section
  • “The matte black reverse panda dial is in exceptional condition with the silver sub-dials remaining clean and bright.”
  • “The original hands are striking, with large arrow minute hand and orange "lollipop" chronograph hand.”
  • “Both the dial and the hands have aged to a warm yellow coloration, showing no degradation or lume loss under U.V. light inspection.”

Movement

The watch is equipped with the manual-wind Zenith caliber 146-HP, a 17-jewel movement. This caliber is documented as a shared development between Zenith and Movado and represents the last manual-winding chronograph movement utilized by the companies before the transition to the automatic El Primero series.

The caliber 146-HP was utilized across various chronographs from the same era, including specific models from Movado. The auction description reports that the movement has been recently serviced and is currently maintaining accurate timekeeping.

Evidence for this section
  • “This specific Zenith features the impressive 17 jewel Zenith 146-HP movement”
  • “This was the last manual wind movement caliber by Zenith-Movado before being superseded by the automatic El Primero movement.”
  • “The watch was just serviced and is keeping time perfectly.”
