I use mine at work!

Very useful, especially the dynamic time function. I set the elapsed time in the stop watch and start it at lift off. I then multiply the stop watch (countdown timer now) with the hourly fuel burn. The active countdown display converts to the fuel remaining display for the actual burn and you can watch it count down to zero.

Of course the display is a linear function and the actual burn decreases as the weight of the aircraft lessons as the aircraft burns fuel. But it is correct at the start and the finish and close in the middle!

On arrival it is easy to change time zones by adding or subtracting the hour difference which automatically changes the DOW and date indication.

Of course exchange rates go into the memory for ease of conversion.

There is a number of the day of the year function, which is the same as the TMI (track message indicator), a code to designate current day tracks across the Atlantic.

Sooooo, very useful, and I think a fantastic tasteful design.

A picture of a restoration done for a friend in London. This watch showed up on the antiques roadshow when he displayed his LED watch collection as part of the show.

And let's not forget the first calculator wristwatch ever made!
