Youtuber Casey Neistat spotted wearing a Doxa

Casey Neistat's April 2023 YouTube vlog 'AI made this VLOG' delivered an unexpected horological treat: the New York filmmaker and content pioneer is seen wearing a vintage Doxa Sub 300T Searambler on an orange NATO strap — and a closer look at the dial reveals the coveted Aqua-Lung / US Divers Co. co-branding, making this a genuinely significant piece of dive watch history.

The Doxa Sub 300T was introduced in 1969 as a purpose-built professional dive instrument, developed in close collaboration with the Cousteau diving team and distributed in the United States through Aqua-Lung's US Divers Company. The 'Searambler' designation identifies Doxa's silver-dialed version within the original Sub 300T lineup, which also included the iconic orange 'Professional,' the black 'Sharkhunter,' and the yellow 'Divingstar.' The Sub 300T measures 42mm in steel, houses an ETA 2783 automatic movement, and features a unidirectional elapsed-time bezel with the distinctive anti-decompression nitrogen saturation scale marked in feet and meters — a functional innovation that set the watch apart from contemporaries in 1969.

The Aqua-Lung dial variant is among the most sought-after configurations in vintage Doxa collecting. These were distributed exclusively through US Divers Co. retail channels, meaning production numbers were limited compared to standard export references. The presence of the Aqua-Lung helmet logo at the six o'clock position and 'US Divers Co.' text confirms this is an early 1970s example, likely predating Doxa's temporary market exit in the mid-1970s. The orange seconds hand with lollipop tip and date aperture at three o'clock are consistent with reference 641.10 production.

Neistat has long cultivated an identity around functional, purposeful gear rather than status symbols, and the Doxa fits that narrative precisely. The watch is worn rather than displayed — the case shows honest patina, and the orange NATO strap keeps things utilitarian. It is the kind of choice that signals genuine horological knowledge rather than stylist-driven accessorizing.

On the current vintage market, Aqua-Lung-dialed Sub 300T Searamblers in honest, unpolished condition regularly command between $3,500 and $6,500 depending on completeness and dial integrity. Doxa's modern reissues of the Sub 300T have kept the brand in the conversation, but original Aqua-Lung examples remain the grail for collectors who understand the lineage.
