Yes. Oris lists two 41.5 mm two-tone Aquis Date Calibre 400 variants: a blue-dial model for the US market and a green-dial model for the UK market. Both pair stainless steel with an 18K gold bezel detail; neither is a full-gold watch. Their references and listed regional prices differ, so check the exact version before buying.

What “bi-color” means on these Aquis watches

For these references, “bi-color” describes a stainless-steel watch with gold bezel detailing. The blue version has an 18K yellow-gold turning top ring and a ceramic minutes-scale top ring. On the green version, Oris describes an 18-carat gold bezel edge around a green ceramic bezel insert. The phrase does not mean that the case or bracelet is solid gold.

The two 41.5 mm references

Oris lists the blue- and green-dial examples separately. Match the dial to its reference rather than assuming that every detail shown for one version applies to the other.

Variant Reference Region and listed price Configuration details
Blue dial 01 400 7769 6355-07 8 22 09PEB US; USD 5,150 listed on Oris’s US page on 2026-10-07 41.50 mm stainless-steel case; 18K yellow-gold turning top ring with ceramic minutes-scale top ring. Oris US product listing
Green dial 01 400 7769 6357-07 4 22 77FC UK; GBP 3,500 listed on Oris’s UK page on 2026-10-07 41.5 mm; stainless-steel bracelet; 18-carat gold bezel edge around a green ceramic bezel insert. Oris UK product listing

These are regional manufacturer-listed prices recorded on 2026-10-07, not a like-for-like price comparison or a resale valuation. They do not establish current stock; check the relevant Oris page or an authorized retailer for current price and availability.

Movement and listed specifications

Oris identifies the movement in both variants as automatic Calibre 400 and gives a 120-hour power reserve, which is five days. The UK listing also describes the movement as having high anti-magnetism, but does not state a numerical magnetic-resistance rating.

Specification Blue-dial US reference Green-dial UK reference
Case size 41.50 mm 41.5 mm
Water resistance 30 bar 30 bar
Power reserve 120 hours 120 hours
Interhorn width 22 mm Not stated on the cited Oris UK listing
Functions Central hours, minutes and seconds; date window; instantaneous date; date corrector; stop-second Not stated in the cited product details
Crystal and caseback Domed sapphire crystal with internal anti-reflective coating; screwed see-through sapphire caseback Not stated in the cited product details

These are manufacturer-listed specifications, not independent measurements or test results. In particular, a 30 bar rating is the stated specification; it should not be read as evidence of a pressure test performed for this article.

  • Bezel material type: Ceramic bezel ring with 5 minute scale.

Bracelet, straps and fit

The green reference is listed with a stainless-steel bracelet. For the blue reference, Oris lists a 22 mm interhorn width and shows fitting strap options, including rubber, as well as a stainless-steel bracelet for Aquis Date Calibre 400 variants. That width is useful when looking at straps, but it does not establish that a third-party strap, end link or attachment will fit. Confirm compatibility with the exact reference before ordering.

Warranty and where to check availability

Oris lists a basic two-year warranty for these watches. The brand says a free extension to 10 years is available upon MyOris sign-up for this movement; the 10-year period is therefore conditional, not the unqualified basic warranty duration. Oris directs customers to its boutiques or retailers. Verify that a seller has the exact reference and confirm the warranty terms for your purchase region.

To look for the exact model on a marketplace, use the full reference alongside the search phrase “Oris Aquis Date Calibre 400 41.5mm two-tone watch.” An official Oris product listing does not by itself confirm an Amazon listing, seller quality, stock or third-party strap compatibility.
