As a flying instructor and watch designer, René Attias has two passions: flying and watches. In the mid-seventies he designed watches for pilots and created his brand, “Navitec”, which is well known to pilots. Lots of planes are indeed fitted with the on-board Navitec 1 chronograph, making its easier to read the time and timings.

In the continuity of instruments used to improve flying conditions, René Attias’ patented graduated bezels, as used on his designs, have contributed, to a certain extent, to simplifying navigation when flying for pleasure.

In 1980, he decided to create the “Tango Charlie” watch range for the general public, fitted with the functions that ensured the success of Navitec amongst pilots but in a more fashion spirit, with outsize models using bright colours or combining materials such as gold, steel, diamonds or even rubber.

The latest in a long series of models, the “Tango Charlie Automatique” chronograph is fitted with a mechanical Swiss movement – 37 jewels, 28,800 alternations/hour – with personalised Navitec rotor. It has a working span of around 42 hours, high precision adjustment in 4 positions (0/+10 seconds tolerance per day), date with rapid corrector and time adjustment with stoppage of seconds. It shows hours, minutes, seconds and has 3 counters (totalising 60 seconds, 30 minutes and 12 hours).

The case (48mm, thickness 12 mm) in polished and brushed 316L stainless steel, is water-resistant to 20 bars, and is made in 2 pieces. It has a patented system of interchangeable “60 minute” bezels decorated with 4 steel horsemen, screwed buttons and crown, an anti-reflection glass and sapphire back.

The white dial with luminous indices and hands (Super luminova) is equipped with red markers for standard Level 1 and Level 2 turns on the minutes dial zone and surrounded by graduated flange with the calculation rule.

Tango Charlie Automatique comes with a white leather or alligator strap.

The BC4 collection is taking the Oris World of Aviation to new heights.  But it is style, not altitude that makes the BC4 Chronograph and Pointer Day real high flyers.

The black dials and elegant white numerals are chic; the red markers for the date, days and minutes are bold. The intriguing three date display at 3 o’clock calls to mind the scrolling numbers of flight instruments.  The repeated presence of the striking small second display at 9 o’clock shows consistency and reliability. This also appears on the BC4 Flight Timer – the third member of the collection.

The Chronograph is a watch made for action.  As the seconds, minutes and hours are counted you’ll see how time really flies.  The Pointer Day is a 21^st century take on the traditional and beloved Oris original.  Both models are protected by the Oris Quick Lock Crown system – a parachute to help avoid accidental adjustment.

The case design of both models is based on the shape of a flight instrument, and the soft, stitched, gaucho leather strap and clasp look exactly like an aircraft seatbelt. Keep your eyes on the dial and don’t look down! One glance at either of these new models and you’ll feel like you’re flying.  That’s why Oris is the intelligent choice.
