The Aquis and Divers Sixty-Five are not simply modern and vintage-looking versions of the same Oris. In these exact references, the Aquis is a green-dial steel watch with a ceramic timing ring and a thirty-bar rating. The smaller Divers Sixty-Five combines a black face with a bronze case and bracelet, creating a different material proposition.
The current 733-1 movement and forty-one-hour reserve are shared, so the decision belongs largely to the exterior. Choose the Aquis if its contemporary steel construction and bracelet are the attraction. Choose the bronze Sixty-Five if you want that material’s evolving appearance and its more historical design vocabulary.

Two histories behind the decision
Oris introduced its first dive watch in 1965 and returned to that design story with the Divers Sixty-Five in 2015. The modern family subsequently expanded through colours and materials, including the bronze watches from which this quieter black-dial Sepia configuration developed. The Aquis follows a separate contemporary path, with recent redesign work refining its case, dial and bracelet rather than reproducing the older diver. These histories explain different priorities without making the Sixty-Five an unchanged vintage watch. Both are current products with modern movements and sapphire, but one makes historical visual cues and bronze central, while the other concentrates on an integrated-looking steel sports-watch package.
The movement does not decide this pair
Both current product listings identify 733-1 with forty-one hours of reserve. It would be misleading to award one a longer duration by borrowing specifications from an Aquis Calibre 400 or an older, differently listed Divers reference. Those are separate comparisons.
That shared mechanism is helpful because it puts attention on the differences which actually exist. If you prefer the bronze watch, you are not giving up a reserve advantage offered by this particular Aquis. If you prefer the green Aquis, its appeal comes from its construction and design rather than a fundamentally different power system. The selected references make a much cleaner comparison than broad collection names.
Bronze is a material preference with visible consequences
The Sixty-Five’s bronze case and bracelet are intended to develop a changing surface. That is a central reason to choose the watch, rather than an inconvenience that can be ignored during the purchase. Its closed steel back also makes the construction more specific than a description of the whole object as bronze.
The Aquis offers a more conventional steel exterior and a ceramic timing ring. If a consistently steel-coloured bracelet is part of your ideal watch, the bronze Sixty-Five is not a close substitute merely because its diameter is smaller. If the prospect of changing patina is the attraction, the Aquis cannot recreate that particular relationship with the material.
Different pressure ratings support different briefs
The Aquis carries a thirty-bar specification, while the selected Sixty-Five is rated to ten bar. Both have timing bezels and dive-watch styling, but those shared features should not cause their ratings to be merged. The exact current product information is more useful than assumptions based on appearance.
The Aquis’s broader green-dial case and closely integrated-looking bracelet support its contemporary sports-watch identity. The bronze model’s black dial, domed sapphire and narrower case create a more historical impression. Their appearances are not proof of their relative robustness, but the manufacturer ratings give a concrete difference to consider alongside the styling.
The smaller model is not the whole small-watch answer
This Sixty-Five measures thirty-eight millimetres, compared with the selected Aquis’s forty-one and a half. That makes it the smaller diameter here, but other Aquis sizes exist. A buyer chiefly motivated by fit should not conclude that every Divers Sixty-Five is smaller than every Aquis.
Choose this Aquis when the green dial, steel bracelet, ceramic ring and higher pressure rating form the package you want. Choose this Divers Sixty-Five when black and bronze, a smaller case and the older-looking silhouette are the main attractions. Compare the complete bracelets and material expectations before deciding. The shared movement means the best answer can remain focused on the watch you actually want to look at and handle.
