DOXA Sub 300T Sharkhunter

Partially verified

The Doxa Sub 300T Sharkhunter is a self-winding mechanical diver's watch, characterized by its black dial and distinctive stainless steel case design. This specific example features what is described as a thin case configuration, indicating it may be a transitional model dating to approximately 1968. The watch is equipped with an integrated unidirectional rotating bezel, which includes an orange-colored decompression scale. The dial displays luminous hour markers and matching hands, and a date window is positioned at the three o'clock index. The dial exhibits signs of tropical patination. The watch is presented on a multi-colored striped fabric strap. This piece is reported to be in original condition, including the dial, hands, and bezel assembly.

Object description

Case and Dial

The Doxa Sub 300T Sharkhunter features a stainless steel case constructed in an early thin profile. This architectural detail is interpreted as a marker of a transitional period for the model series. The dial is black, differentiating it from other models in the Sub 300 family, and displays a light tropical patination. The dial also carries the signature of the maker and the model name, along with the notation 'SWISS T' and '<25 mc' at the bottom.

A date window is located at the 3 o'clock position. The hands and hour markers retain their original luminous material. Encircling the dial is a metallic bezel which incorporates an orange-accented decompression scale. The bezel appears to be in an original state, consistent with the other components of the watch face.

Evidence for this section
  • “featuring an early "thin case" design that leads us to believe it is a transitional piece dating to approximately 1968”
  • “lovely original dial showing a light tropical patination”
  • “The hands, hour markers, and bezel are in excellent original condition as well”

Movement and Functionality

The watch is powered by a mechanical self-winding movement, a feature noted as consistent with the technical specifications of the wider Sub 300 range. The watch functions as a diver's instrument, supported by the rotating bezel which allows for the tracking of dive times.

The movement drives the timekeeping and the date function, which is adjusted through the crown located on the side of the case. No specific caliber number is provided, though the mechanical nature of the watch is explicitly documented.

Evidence for this section
  • “mechanical self-winding movement, and host of innovations that makes the Sub 300 a thing of legend”

Condition and Attribution

The auction description reports the watch to be in good condition, noting that the primary aesthetic components—specifically the dial, hands, and bezel—remain original. The dial exhibits a distinct tropical patina, which is characterized by a lightening or color shift due to age.

The watch is attributed to the 1968 period based on the specific thin case design. All reported details regarding the watch's originality and provenance are derived from the vendor's assessment.

Evidence for this section
  • “This example is of particular note, featuring an early "thin case" design that leads us to believe it is a transitional piece dating to approximately 1968.”
  • “it is also the same version that Jacques Cousteau, the pioneer of SCUBA himself, chose to wear.”

Open research questions

  • What is the specific movement caliber installed in this transitional case?
  • Does the case back contain serial numbers that correspond to the proposed 1968 production date?
