General Features

Bezel: The Breitling Navitimer 1’s rotating slide rule bezel is what secured this watches notoriety in the aviation industry. It still remains a useful tool today, enabling quick calculations for tasks such as currency conversions and calculating a tip.

Dial: At first glance the Navitimer 1’s dial appears busy but, even with its iconic trio of sub-dials, it’s surprisingly easy to read. Those looking for something cleaner should look for the Navitimer 1 Automatic 38, controversially designed without subdials.

Case: Three subdials and a bezel of this complexity require a case bigger than most. The original was 42 mm versus the standard 35 mm case of the time. But in recent years, the Navitimer 1 has gone even larger - to 46 mm for the classic edition and 48 mm for the GMT.
