Oris Big Crown ProPilot 10-Day Movement/114 7746 4164-Set 1 22 72FC Watch

This latest model, the Oris Big Crown ProPilot Calibre 114, expresses Oris' deep connection with aviation, having produced the first pilot's watch in the 1910s.

The watch also marks the debut of Oris' in-house manufactured calibre 114, which offers a 10-day power reserve, a non-linear power reserve display and a 24-hour second time zone.

The Big Crown ProPilot, a pilot's watch that has long enjoyed a loyal following, is now equipped with the Calibre 114, the fifth in the series following the Calibre 110, which Oris developed in-house to commemorate its 110th anniversary.

This is truly the ultimate combination of watches.

The Calibre 114's greatest features are its patented power reserve indicator, which keeps it running for an astonishing 10 days, and its 24-hour second time zone, which can be set precisely in 30-minute increments.

Although it is hand-wound, it is also attractive for its high precision.

The crystal is a double-sided domed sapphire crystal with an anti-reflective coating on the inside.

The case size is a slightly larger 44mm in diameter, giving it high visibility and presence on the wrist.

At 3 o'clock is a patented non-linear power reserve indicator that shows the remaining amount of winding in the mainspring.

The small second and date display are neatly placed at 9 o'clock.

Equipped with a GMT function that allows you to simultaneously see the main time and second time, the inner bezel features a 24-hour scale and a red GMT hand at the tip that indicates the second time.

It supports not only one-hour time zone differences but also 30-minute time zones, allowing for more accurate time difference display.

The indexes and hour and minute hands are treated with Super-LumiNova (BG C3), which luminesces in bright places and glows in the dark, ensuring excellent visibility, which is essential for a pilot's watch.

The high-quality dark brown crocodile leather strap comes with a holding buckle for easy attachment and removal.

The strap stays connected even when you remove it, so you don't have to worry about dropping the watch when putting it on or taking it off. It's also less likely to wrinkle when you put it on or take it off, so it's a buckle that's especially recommended for leather straps.

The back cover is a see-through case back , allowing you to enjoy the beating of the mechanical movement, which is the heart of the watch.
