The Christopher Ward C65 Dune Aeolian is a refresh of the brand’s field-watch line, with a textured, color-led dial and a more refined presentation. The collection includes Automatic, GMT and Bronze COSC configurations, but the published specifications below are specifically for the C65 Dune Automatic; check the exact reference for the others before comparing or buying.
What changed with the Aeolian collection?
Aeolian is a new surface and color treatment within the C65 Dune line, rather than a reason to assume every watch in the collection has the same movement or case. Christopher Ward’s brochure presents the Dune as a three-watch collection that combines field-watch utility with a more polished look. It names the collection after Dune du Pilat in Aquitaine and highlights a 38 mm Light-catcher case, domed crystal and applied twin-flags logo. The official C65 Dune Aeolian brochure describes the Aeolian dial surface and colors as central parts of the design.
WatchPro reported the collection’s launch in 2025, calling it Christopher Ward’s first launch of that year after a limited-edition Dune collaboration with Oracle Time. That is launch context, not confirmation that every model remains available now. WatchPro’s launch coverage identifies Automatic, GMT and Bronze COSC versions.
Christopher Ward CEO Mike France described the balance the brand intended: “Calling Dune a field watch explains it,” he says. “But it doesn’t do it justice. Yes, it’s all-purpose and fuss-free, but it’s sophisticated, too.” The official brochure attributes the quote to France.

Which C65 Dune Aeolian model should you choose?
Start with the feature you need, then compare the precise reference. The collection includes an Automatic, a GMT and a Bronze COSC configuration, but those names alone do not establish a complete specification or price comparison.
- Choose the Automatic if you want the three-hand automatic configuration described by the published Automatic sheet. The figures above apply to that model only.
- Consider the GMT if a second time-zone complication is the priority. Confirm its movement, dimensions, water resistance and case material on the listing for that reference.
- Consider the Bronze COSC if bronze and the stated COSC designation are central to your choice. Verify the particular model’s case details and certification information rather than inferring them from the Automatic sheet.
For a meaningful comparison, check movement and complication, case material, dial and color, dimensions, water resistance, certification, price and current stock for each reference. The launch coverage and brochure establish multiple configurations, but do not provide a complete current model-by-model specification and price matrix.

What to verify before buying
- Exact reference and specifications: Open the manufacturer’s live product page for the model you intend to buy. Confirm its dimensions, movement, water resistance, case material and any certification against that reference, not another C65 Dune variant.
- Price and availability: Check the live listing for your market. Current regional prices, stock and configuration availability are not established by the launch information.
- Strap fit: The Automatic specification sheet gives a 20 mm strap width. This makes other 20 mm straps a possible option, but width alone does not confirm that every third-party strap will attach properly; check compatibility with the exact reference.
- Purchase terms: Review the current warranty and return terms on the seller’s or manufacturer’s live page before ordering.
