Case and Dial

The watch is housed in a 42.5mm stainless steel case defined by the source as a 'No-T' thin-cased version, a configuration reportedly produced for only one year. The front is protected by a domed acrylic crystal. The unidirectional steel timing bezel is engraved with the U.S. Navy's no-decompression dive timing scale, featuring red numerals. The matte black dial includes printed indices displaying light, even patination. The watch utilizes an all-white handset for timekeeping, a pairing that contributes to the 'Whiteshark' nickname cited in the source. A date aperture is positioned at the 3 o'clock marker. The case is completed by an unsigned locking crown and a caseback engraved with a sailing ship, which the source uses to confirm the first-generation origin of the piece.

History and Production

Introduced in 1967, the DOXA Sub 300 series represented a development in the design of diving instrumentation. This particular watch belongs to the initial production year of the model line. As a 'No-T' variant, this watch is identified as part of a limited production window within the first year of the series.

Condition and Maintenance

The auction description reports that the object has undergone a recent professional case refinishing and a mechanical service. The case exhibits the results of this work, and the watch is currently paired with a blue textured rubber strap. The printed indices on the dial are described as having developed a light, even patination. The watch is presented as an example of a first-generation production unit. The crown is identified as an unsigned locking type, consistent with the original design specifications reported by the source. All technical details, such as the bezel scale and dial configuration, are consistent with the features outlined for the initial Sub 300 output.
