Status: Available
Condition: Excellent Pre-Owned
Scope: Box, Papers, and Cards

Case Notes

The ProPilot has always been Oris’ answer to the everyday aviation watch: clear, practical, and purpose-built without becoming visually busy.

This latest 41 mm version sharpens that formula considerably.

The green dial brings just enough color to separate it from the usual black pilot-watch palette, while the broad Arabic numerals, clean minute track, and straightforward date display preserve the legibility that defines the collection.

The stainless-steel case is paired with a steel bracelet, giving the watch a more substantial and versatile feel than the strap versions while keeping the overall design restrained.

Inside is Oris Calibre 733-1, an automatic movement running at 28,800 vibrations per hour with approximately 41 hours of power reserve.

This example dates from 2026 and presents in Excellent Pre-Owned condition. It includes its Box, Papers, and Cards and is currently sized to accommodate approximately an 8-inch wrist.

The watch also remains within its Oris factory warranty period.

Collector Provenance

The ProPilot occupies a useful place within the Oris catalog.

It is not a heritage reproduction and it is not trying to mimic a vintage military watch. Instead, Oris has built the line around contemporary aviation-watch principles: high legibility, durable construction, practical proportions, and a design language that remains recognizable without becoming decorative.

The current generation refines that idea into a cleaner 41 mm package.

Oris itself describes the new ProPilot Date as an aviation watch for everyday adventures, emphasizing a crisp, legible dial and a case designed to be both rugged and understated.

That balance is exactly what makes the reference work.

Design Provenance

The green dial is the distinguishing feature here.

Rather than overpowering the watch, the color sits beneath the functional pilot-watch layout, allowing the Arabic numerals and handset to remain dominant.

The steel bracelet adds another layer of versatility.

On leather, the ProPilot leans more heavily into traditional aviation-watch territory. On steel, it becomes a broader everyday sports watch that can move easily between casual use and a more polished setting.

At 41 mm, it also avoids the oversized proportions traditionally associated with many modern pilot watches.

Technical Provenance

Oris Calibre 733-1 is a straightforward automatic movement designed around reliability and ease of ownership.

It runs at 28,800 vibrations per hour and provides approximately 41 hours of power reserve.

The watch includes central hours, minutes and seconds, an instantaneous date display with corrector, and stop-seconds functionality for precise setting.

The surrounding case is equally practical: domed sapphire crystal with internal anti-reflective coating, screwed caseback with display window, and 100 meters of water resistance.

From the Case File

This is the kind of watch that earns wrist time by being easy.

The 41 mm case is substantial enough to feel like a modern sports watch without being oversized. The green dial adds personality without compromising legibility. The steel bracelet makes it appropriate across a wide range of settings.

And because this example dates from 2026, it is still a very fresh watch.

Case 661 presents in Excellent Pre-Owned condition, includes its Box, Papers, and Cards, retains active Oris warranty coverage, and is sized to accommodate approximately an 8-inch wrist.

BST Verdict

A modern pilot watch that does not need to shout about being one.

The 41 mm case, green dial, steel bracelet, sapphire crystal, and clean aviation-inspired layout make the ProPilot Date particularly easy to wear, while the 2026 date, Excellent condition, BPC, and active factory warranty make Case 661 an especially strong pre-owned example.

Every case deserves a closer look.
