The Breitling Watch Source Forums

I purchased a used Breitling with the following inscribed on the back (Chronographe 100m, D55046, 1 977). It is stainless with a gold bezel, a gold and stainless bracelet, a black face with three small gold faced dials. The only dealer in town "believes" it to be a Chrono Sextant. Can someone suggest how I might locate tech data, instructions on how to use the chrono features and other facts such as year produced, etc.

You've already found the right place.

D55046 is the reference number for a stainless steel Chrono Sextant with a gold bezel and the page about it is here - http://www.breitlingsource.com/watch_de ... er_80.html

In terms of the chrono functions - push the top buttin to start it, the top button again to stop it and then the bottom pusher to reset the chrono when stopped.

Thanks Roffensian---Any idea of the year of manufacture? And the three dials--The bottom, middle is a second continous sweep hand I suppose and is the upper right hours ( one revolution = 12 hrs?) and the upper left minutes (one revolution = 30 min?)

It's mid 90s - no way to date it to an exact year with watches of this age - they weren't date coded until later and the serial is not sequential.

In terms of the subdials - you've now confused me. Are you saying that the hand that always moves is at the 6 o'clock position? I think on the chrono sextants it was always at 3 o'clock. Chrono Jetstream had the running seconds at 6 o'clock but that's a different reference - 55048.

Can you post pictures?

Yes, the second sweep is at the 6:00 o'clock position. I will try to post some pics. Excuse the quality.

OK, let me attempt to clear up some of the confusion by adding more to it.
The OP's pic is of a Chrono Sextant. I believe that the pic here http://www.breitlingsource.com/watch_details/Windrider_80.html was determined in an earlier thread to be that of a Chrono Cockpit without a date and I don't think the pic has been changed since this thread http://breitlingsource.com/phpBB2/viewtopic.php?f=9&t=10238&hilit=sextant where the determination was made.

Thanks br549. So in your opinion my watch is a Sextant. Now, bear with me, I have a few more questions. The sub-dial at the 3:00 o'clock position is labeled from the 12;00 O"clock position clockwise o,3,6,9 -does this dial measure hrs.? The dial at the 9:00 o'clock position has nos. of 30,10,20 at 120 degree intervals - does this dial measure minutes and the 6:00 o'clock sub-dial is secs. Also there are small nos. on a scale around the mailndial on irregular spacing, kind of like a log scale. What is this scale?

The subdials are as you say running seconds at 6:00, chronometer minutes and hours at 9:00 and 3:00 respectively. The scale around the main dial is the tachymetre scale used for calculating speed over a known distance.

Thanks br549, you have been most helpful---"Hook'em Horns"

You're welcome, and it's "Go Hogs!"

I forgot about that whole sextant / cockpit thing a couple of months ago. I should have realised last night when I posted about the Jetstream as it's the same movement.

Nice catch br549!

Roffensian, Any idea on the original cost of the watch and bracelet or today's worth?

I don't have a price list from that period so no idea of price when new. eBay or www.chrono24.com.

Chrono 24 has these right now - not quite the same as yours but give you some idea (not sure why the gold one is so cheap) - http://www.chrono24.com/en/search/index ... TERIAL_ID=
