Its diameter is smaller, but that figure alone cannot tell you how either size will fit your wrist. For a current, specific example, Oris lists the blue-dial reference 01 733 7732 4135-07 4 21 64FC with a 39.50 mm stainless steel case, 300 m water resistance and a 41-hour power reserve.
What “39.5 mm” means for the Aquis Date
In January 2018, Monochrome described the 39.5 mm Aquis Date as a smaller companion to the 43.5 mm Aquis Date, connecting the model to the Aquis Date design introduced in 2017. The number refers to the case diameter; it is not a complete measure of how large a watch wears. The available source does not establish lug-to-lug length, thickness, or a verified wrist-fit comparison, so those details should not be inferred from diameter.
Choosing between 39.5 mm and 43.5 mm is therefore a case-size preference, not a guaranteed fit outcome. If wrist presence matters, compare the exact watch on your wrist or check the full dimensions for the particular reference before buying. The documented 39.5 mm specifications below apply to named references, not automatically to every Aquis Date variant.
Specifications for the current blue 39.5 mm reference
Oris’s regional product page identifies reference 01 733 7732 4135-07 4 21 64FC as a blue-dial Aquis Date with a rubber strap. Its listed specifications provide a concrete current reference point:
#1 Best Overall
- Case: 39.50 mm, multi-piece stainless steel.
- Top ring: ceramic with a minutes scale.
- Crystal and caseback: domed sapphire crystal with anti-reflective coating on the inside; screwed see-through mineral-glass caseback.
- Water resistance: 30 bar, or 300 m.
- Movement: automatic Oris Calibre 733-1, with date and stop-second functions.
- Power reserve: 41 hours.
- Frequency: 28,800 vibrations per hour (4 Hz).
- Interhorn width: 21 mm.
These are specifications for the cited blue reference, not a promise that every dial, strap, or market listing has identical details. Oris’s product listing for reference 01 733 7732 4135-07 4 21 64FC describes it as “a versatile companion.”
Movement: why the power-reserve figure depends on the version
The 2018 introduction article reports a 38-hour power reserve for the Oris 733, described there as based on the Sellita SW200. Oris currently lists Calibre 733-1 and a 41-hour reserve for the specific blue reference above. These figures refer to different source periods and movement descriptions; use the specification attached to the exact reference you are considering rather than treating either number as universal for all 39.5 mm Aquis Date watches.

Dial and strap combinations: launch options versus current listings
Monochrome’s January 2018 coverage described three dial choices—blue, matte black, and polished black—and configurations with a steel bracelet, dark brown leather strap, or black rubber strap. Those are launch-era options, not confirmation that every combination remains available today.
Oris currently lists the cited blue reference with a rubber strap and gives its interhorn width as 21 mm. The official green-variant listing is reference 01 733 7732 4157-07 8 21 05PEB. Oris shows 21 mm fitting strap and bracelet options, but nominal width alone does not establish compatibility with every aftermarket strap: check the exact reference and attachment interface before ordering.
