The Oris Big Crown series is the origin of Oris aviation watches.

The Big Crown was highly praised and loved by US military pilots during World War II in the 1940s.

The collection features a large crown that is easy to operate even while wearing gloves, which is the inspiration for the name, as well as a pointer date developed by Oris.

This collection still has many fans due to its practicality, visibility, and design.

Oris has been producing only mechanical watches, a tradition that has been used since ancient times, for over 100 years. Among Swiss watch brands, Oris is one of the few brands that specializes in mechanical watches, and has a history and tradition that allowed it to withstand the quartz crisis that caused the downfall of many Swiss watch brands.

Yes, even when the watch industry was facing a crisis, they never doubted the future of mechanical watches, and they are a brand that has stuck to their mechanical mindset by continuing to produce only mechanical watches, not quartz watches.
