I bought a Breitling Superocean Chrono (A13340) from "Sakal" duty free shop at Ben Gurion Airport in Tel Aviv Israel on 9-12-2010. The "attestation de chronometre" certificate number (2576586) is different from the serial number on the back of the watch (2424151). I discovered this after I purchased the watch. I brought it back for the right certificate to the strore after 2 months in February 2011, when I was revisiting Tel Aviv. I was told by the Sakal store manager that those numbers do not have to match, which I believe is wrong. My earlier Breitling (Cool Ocean, Quartz) had both numbers matching. How can I reach Breitling main office to have the real certificate sent to my address? Many thanks. Ozgur Kutay

You can take it to any jeweler and they would be able to do that replacement for you.

You really should send it to Breitling via an authorized dealer. Breitling will be able to ensure the repair meets their standards including waterproofness.

The number on the box is not the serial number.
The serial number is on the watch (if its genuine) and on the paperwork that came in the box.

The bezel rotates (manuall) so that you can set the time you have to dive, next to the minute hand. Then as the minute hand rotates, you can see how long you have left before your oxygen runs out.

Keep in mind that I dont have the watch in my hand... :-)

If this is an authentic Breitling...

You should have 2 buttons on the right with the crown between them. The crown screws down so you need to unscrew it before you attempt to set! Once unscrewed with gentle pressure pull the crown out. There should be 2 clicks, pull to 2nd click or furthest distance from case. That should be the time setting mode. Turn clockwise until the date changes then set your time. To change the date push back to the 1st click and that should be the date set mode. One direction will be for day and the opposite will be date. I believe that if you pull the crown back to 2nd click and push your buttons that should change the subdials for chrono. You might need to push both buttons at the same time.

Ive set Breitlings before but they arent a common watch we see. Most people dont use the Chrono so if the directions dont work for setting those then I wouldnt worry too much about it! Not many people are going to notice those. :-) Also be so very careful if its a real Breitling as they are a very expensive to fix! :-)

***DONT FORGET TO SCREW THE CROWN BACK DOWN OR YOU WILL GET WATER INSIDE THE WATCH!***

Unscrew the crown, (it's water resistant) pull the crown out, 1st click sets mins. All the way out sets seconds.
Push back in when done & screw crown down to keep it watertight.
Do NOT overtighten.

The watch should last 36 hours from fully wound. If your wearing the watch and using a watch winder and its still stopping, you have a problem with the mechanism. Get it serviced. (its probably just a clean and oil req'd)
