Yema has unveiled a collection of three versions of its Urban Sport: Flyfgraf for aviator, Yachtingraf for sailors and Rallygraf for motoring enthusiasts.
They all share the same hexagonal steel case and integrated jubilee-style bracelet (or the option of a leather straps in different shades).
Differences come in dial treatments and bezels.
The black and yellow Flygraph has an outer rotating bezel that combines with an internal bezel of to help make a multitude of in-flight calculations including average speed, average fuel consumption of an aircraft, or even converting nautical miles to miles, and miles to kilometers.
Yachtingraf comes in red, white and blue with a bi-directional 60 minute aluminium bezel that has a 15 minutes countdown marking for regatta race starts.
The monochrome Rallygraf also has a bi-directional bezel with aluminum insert with a tachymeter scale that enables car racing drivers to calculate average speed (in km/h) in combination with the elapsed time graduation of the internal bezel.
All three use the second-generation in-house Caliber YEMA2000 which has an accuracy raging of +/- 10 seconds per day and a power reserve of 42 hours.
They are priced at $829 on the strap or $890 on a steel bracelet.
There is also the option of a collector’s case of all three watches in a leatherette case that can be bought for $2,669.
