Re: WristWatch Selection
It's gone - sold it
I have kept the EMS, the GPS, the alt hold and the autopilot

"For those who have one (or similar) there is a marker on the inner and outer dial at 36. This isn't explained in the instructions, nor could anyone help in the shop where it was bought. Does anyone know what this is for? I would guess that 36 maps to 3600 seconds in an hour so might have something to do with converting rates between per second and per hour or minute?"
I bought my Navitimer in HKG in '71 and have used it ever since. Still got the original handbook. You're right, the '36' is the second index and is used for calculating seconds to cover a given distance.
Quote from the handbook:
Known: Miles per hour and distance.
Required: The number of seconds to cover the distance.
A pilot is approaching the airport at a ground speed of 120 mph. The fan marker is 1 1/2 miles from the runway. How many secs from the marker to the runway?
Solution: Set 120 on the white dial opposite 36 on the outer black dial. Opposite 1.5 on the white dial read 45 secs on the outer black dial.
Where the white dial is the one that rotates, the outer black dial is its fixed circular slide rule partner.

Re: WristWatch Selection
Thanks HambleOldBoy. It took me nearly 45 seconds to work that one out so I guess the runway would be almost upon me ;-)

Sorry to drag up an old, old thread - but I thought I'd let you all know what I got. Thanks a lot for all the advice - I was on the brink of buying a $300 (CDN) Casio with altimiter and barometer and a bunch of other widgets including a digital compass..
But at the last second I chickened out.
I pined after this Breitling watch:
But in the end I ended up getting a cheap Timex that didn't do much else than have Dual Timezone modes; one which is on "Wife Time" and one that is on Zulu time.

citizen eco drive skyhawk in titanium - use it all the time to look up speed/fuel/distance calcs. only hassle is it doesn't have backlighting, but it has excellent luminecence. doubles as a nice dress watch. about US$350 on ebay.
have a g-shock with fabric strap for sport etc, but often use it flying as it is analogue/digital with excellent features. $US100

My last Citizen ran out of calender so bought a new one off www.21jewels.com and very impressed by both low prices and prompt service. A little skeptical however one of my work colleagues had previously recomended the site.The watch I purchased Citizen Promaster World Time Quartz JQ8010-50E is now priced $108 USD and has all I could ask.Multiple time zones, independant chronograph,alarm,backlight,countdown timer,stopwatch.
Check out the site as there is heaps to choose from

Thanks for that, my Swatch always had a slightly offset hand, which although it had no affect on functionality, it bugged. Now it looks neat and tidy (at 12 o'clock anyway).
Supprisingly this has been the most useful thread ever on PPRuNe!
My top-notch Breitling Navitimer copy, has Seiko internals and my 'second' marker pointer jumped a digit too.
To rectify it, you pull out the crown from its stop, and manipulate the 'lower' reset button (the one that resets your stop watch - assuming the movement is the same) and this will make the pointer move to the next marker, keep pressing the button until it gets to the desired point.

Voeni - I DO use mine when flying.... I looked for some time at several websites and many comics and shops. Eventually I decided to write my own specification and then see if I could find something to match it.
1. It needed to be easy to read in low light levels.
2. A rotating bezel, to make timing legs much easier. (Providing they are < 1 hour) which mine usually are.
Experimenting eventually proved that a dark face with light hands is easier to see in low light conditions.
I eventually found one in the Swiss Army series that met all my requirements. Cost about £80 from Watch Heaven.com. It stays within 30 seconds over 6 months and the battery last about 3 years which I replace it myself....
I was initially tempted by the ones with lots of dials, but came to the conclusion that they're almost impossible to read...especially in poor light!
My trusty old Casio Data Bank is very useful for multiple time zones, but I don't go to 'foreign' that often. And I absolutely agree that analogue is much easier to read than digital. In the race car I shared for many years, all the dials were deliberately positioned so that the pointer was at 12 'o' clock when at the correct temperature/pressure/engine speed was achieved. All could be taken in at a glance. And they were usually black faces with white pointers...

When i got my PPL in 98 i bought a £200 Casio with a flight computer on it's bezel, 24 different time zones including UTC and a 24 hour stop watch!
Now i fly 737's round Europe i use the clock in the aircraft and an Wallace and Gromit egg timer for fuel balancing. How things change when at the coal face. Yes it's great if it looks nice and why not but 1. It has to be accurate and 2. You have yo understand how the thing works

Casio G-Shock (Wave Ceptor/Solar powered)
Cannot speak highly enough of it. Very accurate, light and tough as nails, countless time zones, swish lighting system, numerous alarms etc and all for £80! Great for serious scuba diving depths or alternatively, poling along at FL430!
I've got a Tag, Tissot and a couple of Seikos but the G-Shock is my favourite.
