Is your Big Crown ProPilot
the real deal?
The Oris Big Crown ProPilot is the brand's aviation watch line, named for its oversized crown designed to be operated with flight gloves. With a clean pilot watch dial, day-date complications, and sizes in 41mm and 45mm, it carries a heritage dating back to Oris's original 1938 Big Crown. Its growing popularity has made it a target for counterfeiters. Here's how to spot a fake.
How to authenticate a Big Crown ProPilot
Oversized Crown with Oris Logo
The defining feature of the Big Crown is its oversized crown, which should be noticeably larger than a standard watch crown. It must be properly proportioned relative to the case, with knurled edges for grip. The Oris bear logo should be sharply engraved on the crown face. The crown should operate smoothly with well-defined positions for winding, date-setting, and time-setting.
Dial Legibility and Numeral Font
The ProPilot dial is designed for maximum legibility with large Arabic numerals and a clean layout. The numerals should use the correct Oris typeface with consistent weight and spacing. The "Oris" logo, "Big Crown" text, and "Swiss Made" marking should all be sharply printed. The dial surface should be matte with a uniform finish.
Day-Date Window Alignment
On day-date models, the day and date windows should be perfectly aligned with the dial layout. The text within the windows should be centered, sharp, and easy to read. The day should change cleanly at midnight without hanging between two days. The date wheel color should match the dial color scheme of that specific reference.
Red Rotor Through Caseback
Through the exhibition caseback, the signature Oris red rotor should be clearly visible and spinning freely. The rotor should be a vibrant, consistent red with the Oris name engraved on it. The movement bridges should show proper finishing. Calibre 400 models feature a different rotor design and higher-quality finishing compared to Sellita-based models.
Textile or Leather Strap Quality
The Big Crown ProPilot is often paired with textile or leather straps. Genuine straps use high-quality materials with clean stitching, proper edge finishing, and a solid buckle or deployant clasp with the Oris logo. Textile straps should feel dense and durable, not thin or fraying. Leather straps should show quality hide with even coloring and a smooth lining.
Case Finishing
The ProPilot case should show clean, precise finishing with uniform brushing on the flat surfaces and smooth polished edges where applicable. The lugs should have consistent proportions and well-defined edges. The sapphire crystal should sit perfectly flush in its setting. Check for any unevenness, rough spots, or tool marks that would indicate a counterfeit.

Crown Not Oversized or Poorly Shaped
The Big Crown's most distinctive feature is its oversized crown. If the crown is a standard size, poorly proportioned relative to the case, or has rough knurling with a blurry or missing Oris bear logo, the watch is almost certainly a counterfeit. The crown should feel substantial and well-machined.
Wrong Date Window Position
On genuine Big Crown ProPilot day-date models, the day and date windows are precisely positioned according to the specific reference. If the windows are misaligned, too large, too small, or in a position that does not match known references for the model, the watch is a fake. The text within the windows should also be perfectly centered.
No Red Rotor
Every genuine Oris Big Crown ProPilot has the signature red rotor visible through the exhibition caseback. If the rotor is a standard silver or gold color, if there is no exhibition caseback at all, or if the red appears faded or painted on, the watch is not genuine. The Oris name should also be clearly engraved on the rotor.
Poor Strap Quality
Genuine Oris straps use premium materials with precise stitching and clean edge finishing. Counterfeit straps feel cheap, thin, and poorly constructed with loose or uneven stitching, rough edges, and a buckle that lacks the Oris logo or has a blurry engraving. The strap should feel dense and well-made, not flimsy.

Frequently asked questions
Why is the Big Crown ProPilot crown so large?
The oversized crown is a defining feature of the Oris Big Crown collection, dating back to the original 1938 Big Crown pilot's watch. The large crown was designed so that pilots could easily grip and operate it while wearing thick flight gloves. Modern Big Crown ProPilot models preserve this heritage with a crown that is noticeably larger than standard watch crowns, typically featuring knurled edges for grip and the Oris bear logo on the end. This functional design element is both a tribute to aviation history and a practical feature.
What movements does the Big Crown ProPilot use?
The Oris Big Crown ProPilot collection uses several different movements depending on the specific reference. Most models are powered by the Sellita SW200-1 based automatic movement with a 38-hour power reserve. Newer models in the collection are being upgraded to the Oris Calibre 400, which offers a 5-day (120-hour) power reserve, superior anti-magnetic properties, and a 10-year warranty. Some day-date models use the SW220-1 derivative. All movements feature the signature Oris red rotor visible through the exhibition caseback.
Is the Big Crown ProPilot a tool watch?
Yes, the Big Crown ProPilot is designed as a functional pilot's tool watch. It features high legibility with large Arabic numerals, strong lume for low-light readability, an oversized crown for operation with gloves, and a clean dial layout that prioritizes quick time-reading. Many models include day-date complications for practical daily use. While it is refined enough for everyday wear, its design DNA is rooted in aviation functionality, making it a genuine instrument watch rather than a purely dress piece.
