The Aquis Date 36.5mm is Oris's answer to buyers who want a serious dive tool without wearing a hockey puck on their wrist. It carries the same 300-meter water resistance, rotating bezel, and sapphire crystal as the larger 41.5mm but scaled to a case that works on smaller wrists and under a shirt cuff. If you want legitimate dive capability in a proportionate package, this is the ref to buy.
Oris introduced the 36.5mm Aquis Date in 2018, positioning it alongside the 41.5mm rather than below it. The caliber is the Oris 733, a branded and decorated version of the Sellita SW200-1, offering 38 hours of power reserve and reliable daily accuracy. The case architecture mirrors the larger Aquis exactly: same lug shape, same unidirectional bezel, same crown protection.
There have been no significant generation changes since introduction; Oris has kept this reference stable while refreshing dial colorways periodically. Production continues as of 2025.
Inspect the bezel insert for chips or fading, particularly on older ceramic-inlay examples with colored markers. The crown seal is the most common service point on dive watches that actually see water, so ask whether the seller has used it for swimming and whether it has been pressure-tested recently. On pre-owned examples, check the case flanks for polishing: the brushed sides should retain their matte texture, and heavy polishing rounds the lugs noticeably.
The bracelet's folding clasp, while functional, can develop play over time, so open and close it to check for slop. Confirm the dial variant matches the papers if authenticity documentation is present, as Oris has offered this ref in blue, green, and black with differing indices across model years.
