Daytona Question

[konn42]

I don't want to sound ingnorant, but what is the dial on a Daytona used for? And how does it work?

Thanks.

Scott

Nobody knows. Rolex trade secret or something.

When you say what is it used for, what exactly do you mean?
The large second hand is the second totaliser, the small dial at 3 o`clock is the minute totaliser, up to 30 mins, the small dial at 9 o`clock is the hour totaliser, up to 12 hrs and the small dial at 6 o`clock, is the ordinary seconds for the watch.
The chronograph hands remain stationary unless the chronograph is started and then begin counting, whatever you want to time, a race, the Sunday roast dinner or how long it actually takes for your pizza to be delivered!!

Hi Scott,

Welcome to TRF. I think I've understood your question. Here ya go....you will notice the continuous running second hand is at 6 o'clock, the minute totalliser at 3 o'clock and the hour totalliser at 9 o'clock.

The pusher on the top at 2 o'clock starts and stops the sweep of the large Chrono hand. The pusher at 4 o'clock resets the Chrono hand back to '12'.

Cheers - JJ

I'm referring to the bezel (ie wheel marked with "units per hour")... I dont understand how this works with the chronograph...

Thanks again.

[worktolivelife]

look at the section calculating average speed, in the manual

Okay, look once again at the above picture. Say you've got a car running between 2 points which are say ONE MILE apart.

As the car takes off, you start the Chrono hand. When it passes the second point, you stop the Chrono.

Say the Chrono stops at the '120' mark at the bottom.....so that means the car is doing 120 mph.

Thanks.

Scott

it looks nice

Good try JJ but no cigar.
The speed indication on the outside dial is only for travelling a mile (or kilometer) at a constant speed.
You cant just 'take off' and expect the watch to calculate things like acceleration. Even a Rolex isn't that clever.

This is a good question that was asked.

Does anybody actually use any of these functions regularly?...and I dont mean when you are bored waiting somewhere to see of they actually work.

Personally that dial is way too busy for me....but it is an icon of Rolex.

hey guys, excuse my intrusion on the thread since I am kind of new here and haven't posted much...(mostly just do reading)...but when JJ said it did 120mph, he would be correct if the 120mph is the average speed done between the two points...which accounts for any variances in speed such as acceleration...am i making sense? again, nice to finally put my 2 cents in and hope to make many more posts in the near future.

I've used it many times along with the mile markers on the turnpike to reset the speedometer on my car after a gear change. (one mile in one min = 60mph ect.)

That's right, Ivan. The 120 mph would be the average speed from point to point. There's no way any watch could calculate acceleration or deceleration for that matter!!

And I would have none other than JJ to confirm my fact

Havent used it yet I actually leave it running at all times, I just love everything about the watch it is so perfect in many many ways.

Most people never use all the features, they may know how, but I doubt they use them.
