Oris ProPilot Calibre 111 makes ten days legible

A 240-hour hand-wound reserve is only as useful as the gauge that explains it. Oris puts that question on the ProPilot dial.

• The ProPilot Calibre 111 pairs a hand-wound 240-hour reserve with a non-linear gauge intended to show when winding becomes urgent.
• This black-dial reference uses a 43mm steel case, fluted bezel and leather strap, with the power-reserve display occupying three o'clock.
• Oris lists the leather-strap reference at A$10,400 in its Australian store, where the product page offers an add-to-cart option.

A 10-day power reserve sounds like a simple luxury until it appears on a hand-wound watch. The owner gains long intervals between winding, but also needs to know when the remaining energy matters. Oris places that problem on the dial of its ProPilot Calibre 111, using a non-linear power-reserve display alongside a date and small seconds. The question is whether this is a practical cockpit-style instrument or a complication that asks for too much attention each time the watch is worn.

Ten days need a useful gauge

Oris rates its Calibre 111 at 240 hours, and the watch is wound by hand. The difference from a conventional automatic is immediate: there is no rotor restoring energy while it is worn, so the reserve is entirely in the owner's control. Ten days makes regular winding less urgent, but it also makes a clear reserve display more useful. The dial places that display at three o'clock, with small seconds at nine and the date below the centre. The hours and minutes remain on central hands.

The indicator is non-linear. Oris says its scale shows the remaining reserve with increasing accuracy as the moment to wind approaches, rather than treating each segment of the gauge as an equal slice of time. The watch's broad numerical promise is therefore paired with a more careful account of its final portion. That feels like the right priority: the owner is unlikely to need a minute-by-minute account of day nine, but does need to know when the movement is close to stopping. Whether the gauge is intuitive at a glance is a matter for a wearer to test.

The rest of the dial is textured and vertically brushed, according to Oris. This black leather-strap reference carries a dark dial, large Arabic numerals and a fluted bezel that the brand likens to a jet engine. In the official photographs, the reserve display occupies a sizeable area at three, yet the central hands still have clear space through the middle of the dial. A small orange segment helps identify the low end of the reserve. That is a useful signal on a watch built around its winding interval, although a photograph cannot establish how clearly it reads in every light.

A pilot case around a large movement

The case is multi-piece stainless steel and measures 43mm across. Oris gives no case thickness on this product page, so the stated width is only part of the fit story. The domed sapphire front crystal has an anti-reflective coating on its inner side; a screwed steel back has a sapphire window. Water resistance is 10 bar, equivalent to 100m, and the lug spacing is 20mm. Those dimensions put the ProPilot in a substantial watch category, while the relatively narrow lug width leaves the strap from looking overwide beside the case.

Look through the back and the Calibre 111 is visible rather than hidden by a solid plate. Oris specifies a 34mm movement diameter, hand winding and a frequency of 21,600 vibrations per hour, or 3Hz. The movement has a stop-seconds function and a date corrector as well as its reserve indication. These are not extra decorations placed on a stock time-only watch; they explain why the dial has its particular three-part arrangement. The ten-day reserve is its headline capability, but the useful detail is how the movement makes that capability visible and manageable.

The black leather strap is the option attached to reference 01 111 7808 4164-07 6 20 19LC. Oris also shows a steel bracelet as a separate fitting strap, but this article's price and photographs refer to the leather-strap watch. That distinction matters because the range includes several ProPilot Calibre 111 variants with different dial colours and straps. The exact reference keeps the discussion anchored to one watch rather than making an untidy blend of features from the wider family.

Convenience, with a small ritual

For an owner who rotates watches, 240 hours can mean returning to the ProPilot after several days and finding it still running. For somebody who wears it every day, the benefit is different: winding can become an occasional deliberate act rather than a daily requirement. The non-linear indicator gives that act a visible prompt. I find that a more interesting use of a long reserve than merely putting a larger number in a specification table, because it acknowledges that energy has to be managed by a person.

There are limits to what the official page can show. It establishes the layout, the movement's published figures and the available leather-strap reference, but not the feel of winding the crown or the real-world clarity of the reserve gauge. Nor does it provide a dated announcement for this configuration. The strongest case for the watch is therefore an argument about design rather than recency: Oris has paired a long hand-wound interval with a display intended to make that interval legible. If the gauge feels natural in use, the complication has a job beyond spectacle.

Oris ProPilot Calibre 111 pricing and availability

Oris lists this black-dial leather-strap reference at A$10,400 on its Australian product page, with an add-to-cart option. The page also lists a bracelet variant in the range at A$10,700; that is a different reference and not the price of the watch discussed here. The brand does not state a production limit or an announcement date for this exact watch on the product page.
