YESLAM – AVIATOR I Black TITANIUM Dual Time

YESLAM – Aviator I Black TITANIUM Dual Time NEW

 TRUE AIRSPEED CALCULATOR
AUTOMATIC DUAL TIME, TITANIUM & STAINLESS STEEL - SWISS MADE

With its PVD turbine dial, the new model «Aviator Black » takes off in this series of watches designed specifically for pilots and aviation enthusiasts. This watch has a flight computer, useful for calculatingthe actual speed (TAS = True Airspeed) In-flight and flight preparation. For an unlimited combinations of flight levels and indicated speed, calculation is made by a simple rotation of the bezel. Because of its simplicity, it is a reliable and safe addition thatalso allows any theoretical projection. Based on the «International Standard Atmosphere model», this watch will determine with satisfactory accuracy the true airspeed for each combination of indicated airspeed and flight level. Any inaccuracies detected will be due to the reduction of the system to the size of the watch. This exclusive timepiece offers comfort, accuracy and fascination. The skeletondial, bezel and crown are covered with black PVD which makes it resistance to wear and scratches. This combination of High Quality of Watchmaking and aviation is protected in a case with a unique design in titanium and steel, suitable for “Aviator ”collection.

The ONE and ONLY !
A watch that calculates TAS

In history, man has always been fascinated with two virtually unreachable concepts, time and free
flight. The watch and an airplane are as close as we can get to either.
Many watch manufacturers have tried to combinethe two, with various results. Some have watchesthat look like airplane instruments, others have pictures of an airplane, but never has one been able to invent a watch for this useful function.
This watch has an integrated flight computer*¹) that can be used for in flight calculations as well as flight planning calculations of the True airspeed, TAS for a virtually unlimited*²) amount of combinations of flight levels and indicated airspeed. With just one turn of the bezel.
How did this come about?
The designer is an experienced pilot himself. He holds multiple type ratings on Learjet and Cessna business jets, among others. He has accumulated over 3500 hours of flight time experience, almost
all on jets.
Never stopping to invent and design beautiful things, this time he wanted to combine the beautiful with the useful.

After many months of experimenting and many trials, even a test flight wasn’t shunned, he invented something truly remarkable:

The AVIATOR a watch that will give True airspeed for any combination of flight level (altitude) and Indicated airspeed*²)

With the up rise and integration of electronic and satellite navigation, the calculation of True airspeed
became less and less necessary, but every pilot has and needs a watch.
One thing will never change, we will always be flying through air and there for we will always have an Indicated airspeed and a True airspeed. One equally important as and useless without the other!
It is this gap between practice and theory that made for this intriguing invention.

Based on the ICAO model of the International Standard Atmosphere (ISA), this watch will approximate the True airspeed for every combination of Indicated airspeed and flight level possible*²), within 5 knots. This margin is due to physical limitations of the size of the watch and human error.
Not only is its use made for the aviation industry, its appearance has everything to do with aviation as well. From the obvious, the beautifully engraved fan blades in the dial and the overall look simulating a jet engine, to the less obvious, the use of the materials.
 
*¹ ) The term “flight computer” is used solemnly to indicate the computing possibilities of this watch and shall in no means be interpreted as an actual flight computer.
*² ) possibilities limited by; flight levels between 18’000 and 46’000 feet and IAS between 180 and 370
