Other features include a scratch-resistant mineral crystal and water resistance to 100 meters (330 feet)--offering protection from accidental splashes as well suitable for swimming, snorkeling, and light recreational diving. It comes with a detailed instruction booklet on operating the flight computer features.
![]() Using this watch's flight computer/slide rule feature, you can easily make a variety of calculations including currency conversion. |
This Torgoen watch can be used as a regular circular slide rule or a flight computer. It uses the calculation abilities of a slide rule to calculate time, speed and distance, and fuel consumption, as well as useful conversions such as statute miles to nautical miles, metric units to English units, or US Dollars to British Pounds. Easy to use after just a little practice, you'll be able to perform some calculations more quickly than with a hand-held calculator.
As an example, suppose the conversion rate for the Swiss Franc is SFR 1.60 to $1.00. Rotate the outer scale to match 16 over 10, the outer scale becomes Swiss Francs and the middle scale becomes US dollars. You can leave the scales like that until the exchange rate changes. If you want to convert SFR 4.00 to dollars you look at the number in the middle scale opposite the 40 on the outer scale. The number is 25. You can therefore deduce that SFR4.00 are $2.50 (see example image at right).
Using This Zulu Time Watch
For easy reference in communications, each of the world's 24 time zones has been assigned a letter of the alphabet (less the letter "I" and "O"). The "clock" at Greenwich, England is used as the standard clock for international reference of time in communications, military, maritime and other activities that cross time zones. The letter designation for this clock is Z, pronounced ZULU in the phonetic alphabet.
To set the time, pull out the crown 2 steps and turn. To set a different time zone, pull out the crown out only one step and then turn to one direction to change the date and the other to set the 24-hour hand to indicate a different time zone of your choice. For example, if you are in New York City, at noon, and wish to track the time in Rock Springs, Wyoming (2 hours behind New York), turn the crown until the red 24-hour hand points to 10:00 on the 24-hour scale (5:00 on the 12-hour scale).
