The Breitling Watch Source Forums

Hello, can anyone please tell me what all of the extra numbers on a watch are for? And how to use the bezel ect.?

If you look at the cosmonaute for example, it is covered in numbers. what do i need all of these for?



Thanks for the help

On the Navitimer series you'll see a pretty busy dial. What you see on the outer most edges a slide rule. A slide rule is a precurser to the calculator. http://en.wikipedia.org/wiki/Slide_rule On this type of watch, the slide rule was used to perdorm in-flight calculations. A history of the original slide rule bezel is here:http://forums.watchuseek.com/showthread.php?t=9103

The next set of numbers in are the typical hours/minutes. The cosmonaut has a 24 hour dial, meaning 12 noon is the in the usual 6 o'clock position.

The sub-dials you see will be related to the chronograph. Small seconds, and elapsed minutes and hours are the usual.

This may be of some benefit to you as well in understanding the slide rule aspect of the watch.

ok thank you, and there is just 1 more set of numbers that i can't figure out what are for.

i think it might correspond with the slide rule. but instead of being numbers it is times, so the first to the right is 1:10 then 1:20, 1:30,... up to 2:00 then 2:30, 3:00, 3:30...5:00, 6:00, 7:00, 8:00, 9:00. how do these work, is it for multiplying time?


and a question about the 24 hour watch face, does the second hand and the minute hand go around once or 1/2 every minute/hour?

The times do relate to the slide rule - it's explained in the link that br549 provided.

Second hand goes around once per minute, minute hand goes around once per hour, it's just the hour hand that is geared differently.
