The Oris Aquis Date 43.5mm is a 300-metre-rated automatic diver with a blue dial and rubber strap in the specific US reference reviewed here, 01 733 7730 4135-07 4 24 64EB. Oris lists its Calibre 733-1 power reserve at 41 hours. Its 43.5mm case makes wrist fit worth checking in person, and the Aquis name covers other sizes and configurations that do not share every specification.

Specifications are from Oris’s listing for the cited reference. The brand describes the Aquis Date as an “everyday toolwatch”; that is Oris’s positioning, not an independent wear assessment.
How does the 43.5mm case fit?
A 43.5mm diameter gives this Aquis a substantial footprint on paper, but diameter alone cannot establish how it will sit on a particular wrist. Lug shape, case proportions and personal preference all affect the impression. Hodinkee’s 2024 overview says the next-generation Aquis Date has shorter, more ergonomic lugs, but that design description does not guarantee a comfortable fit for every wearer.

#1 Best Overall
Oris and the sources cited here do not establish a wrist-size cutoff at which the 43.5mm model will or will not fit well. If possible, try it on and assess how the case and lugs sit across your wrist. The 2024 generation also includes 41.5mm and 36.5mm Aquis Date sizes, which are useful alternatives to try if you prefer a smaller watch.
Calibre 733-1 power reserve and Calibre 400 comparison
For the exact reference in this review, Oris specifies a 41-hour power reserve and automatic winding. That is the most relevant figure when assessing this blue-dial, rubber-strap 733-1 model.

The 43.5mm Aquis Date has also been offered with Oris Calibre 400. Hodinkee’s April 9, 2024 overview reports a 120-hour reserve for Calibre 400 and 38 hours for the 733 family. The family-level 733 figure differs from Oris’s current 41-hour specification for this particular 733-1 reference; use the manufacturer’s figure for this model rather than treating all 733 variants as identical.
| Movement option | Power reserve | What the figure applies to |
|---|---|---|
| Calibre 733-1 | 41 hours | Oris’s specification for reference 01 733 7730 4135-07 4 24 64EB |
| Calibre 733 family | 38 hours | Hodinkee’s family-level figure in its April 9, 2024 generation overview |
| Calibre 400 | 120 hours | Hodinkee’s figure for the Calibre 400 option in its April 9, 2024 overview |
The longer reserve is the clearest practical distinction in the reported figures. Confirm the movement on the exact model listing: a 43.5mm case does not by itself identify which calibre is inside.

What does 300-metre water resistance mean?
Oris rates the cited reference at 30 bar, equivalent to 300 metres. This is a manufacturer’s water-resistance specification, not a claim that the watch was independently tested in a 300-metre dive. The rating establishes a substantial water-resistance specification, but it does not replace following Oris’s operating and maintenance guidance for the specific watch.
Can you change the strap or bracelet?
The cited product page lists a 24mm interhorn width and fitting options that include 24mm steel and titanium bracelets, as well as rubber and leather straps. That page’s accessory list does not establish universal compatibility across all Aquis references. Check compatibility for the exact watch and part, and verify availability before ordering.

Price and availability
When crawled, Oris’s US page listed the cited reference at USD 2,400 and marked it unavailable online. That is a time- and region-specific listing, not a guaranteed current price or availability status. Check the exact reference on the local Oris site or with a retailer before purchase.
For historical context, Hodinkee reported Swiss launch prices for the 2024 generation of CHF 2,200 for a Calibre 733 model on rubber, CHF 2,400 on bracelet and CHF 3,600 for a Calibre 400 model on rubber. These are dated Swiss launch prices, not current retail quotes for every market or configuration.

What changed in the 2024 Aquis Date generation?
Hodinkee’s April 9, 2024 overview describes 43.5mm, 41.5mm and 36.5mm versions, with the 733 offered across sizes and Calibre 400 also available in 43.5mm. It notes shorter lugs, a re-proportioned bezel, redesigned crown guards, dial-matched date wheels and updated bracelet and strap options. These are generation-level details; the exact configuration still depends on the reference.
Verdict
The cited Aquis Date is a clearly specified option if you want a blue-dial, rubber-strap Oris diver with 30-bar water resistance and a 41-hour automatic movement. Its main decision points are whether the 43.5mm case suits your wrist and whether the 733-1’s reserve and exact configuration meet your needs. Compare the full reference—not just the Aquis Date name—when evaluating Calibre 400 alternatives, smaller sizes or replacement straps.
