Daytona Function Questions

[FXSTS]

Anyone know of a site where the owners manual for the Daytona is posted, or a good explanation of how the start/stop buttons work? When stopped, should both the large second hand and the smaller dial at 6 oclock stop? Which dials should the reset affect?

Thanks

On the Daytona the top pusher both starts and stops the main stopwatch hand. The lower pusher re-sets it. Upon reset, the main seconds zeros, the 30 min sub zeros (at 3 o'clock) and the 12 hr sub zeros (at the 9 o'clock)

The 6 o'clock sub dial is standard seconds and never stops (unless you let it run out of power).

All other Daytonas work the same except the standard seconds sub-dial is at the 9 o'clock position.

the top screw down button stops and starts the large sweep second hand, elapsed minutes and elapsed hours.
the bottom screw down re-sets the large sweep second hand, minute hand and hour hand.
the 6 o:clock small dial is continuous seconds( not affected by the chrono function)
the 3 o:clock dial is minutes of elapsed time
the 9 o:clock dial is elapsed hours

Appreciate the replies. So basically, if the large sweep second hand is going so are all three subdials?

Thanks!

Correct.

Does anyone know how to use the UNITS PER HOUR on the bezel with the timer?

[ratmotortom]

To make it simple. Time a vehicle moving at a known 1 mile distance. ( Point A to point B = 1 mile ) Start the stop watch and stop it when the vehicle has covered the set distance. The speed will be reflected on the bezel scale. There are more sophisticated ways to use it and a 1 mile distance isn't always the measure, but that is a good example and the simplest way for me to explain it. I'm sure someone can chime in with a better description. ( The key is to know the distance traveled to convert the scale to MPH.)

I am just waiting for someone to ask, "Why don't you just look at the speedometer?"

Because when you are at the track and you are timing your driver's laps............ you can't see the speedometer. The watch is not just for the driver.

Exactly. Plus, it "calculates" average speed over a distance, whereas a speedometer tells the driver the current speed.

But he asked for "Units Per Hour"....

For that, you watch your assembly line as each product is being produced, and time how long it takes to produce one item (or time how long it takes you to chug a beer). you then read off the bezel how many would be produced (chugged) in an hour at that rate.

We have a little primer on the different Chronograph bezels (Tachy, Deci, Tele, and Pulsi) over on our Omega board:

One use is to determine how accurate your speedometer is. If you have signs on the highway that are placed at one mile intervals, you can set your cruise control for, say 65 mph. Start the chronograph right at the first mile marker and stop it right at the second mile marker. See how the speed on the watch compares to 65 mph.

Thanks Tools,

Now I understand how 179 mph is calculated in the Omega Speedmaster example, but how do you work out the mph when the long arm rotates longer than 60 seconds?

It is called a SPEEDmaster, not a SLOWmaster!!!!!
