The Breitling Watch Source Forums

Is that true? Isn't the rest of a quartz watch mechanical? I'd imagine there would still be some interference in the date change mechanism.

Ok as far as I know. There's not a warning against it in my quartz watch manuals as there is in those of my mechanical autos.

The mechanics of changing the date is essentially the same, but quartz watches do not require the same length of time to move the date change mechanism into the running train (which is done to try to minimise the impact on the running train and it's timekeeping).

I was wondering about changing the date at the end of this month. Can I use the quick set for the date or do I adjust the time around until the new date and time is correct?

You can do either, just don't use the quickset date between an indicated time of 8pm and 3am.

Hi everyone, I'm new to the forum. I purchased my first Breitling, a Seawolf SS, in December. Since then I've been reading references to this mysterious 8pm to 3am rule in various forums, but nowhere in the literature that actually came with my watch. Can I safely assume that if my owner's manual makes no such warnings about my Seawolf, I don't need to concern myself with it? From this thread, it sounds like this rule is mainly an issue for chronograph complications, or where the owner's manual specifically warns about it? Thanks for your feedback.

If you bought your watch from an official AD, he should have explained it to you. Shame of him if he didn't

The 8-3 rule is valid for all Breitlings that do not have the 01 in-house caliber, hence for your SS as well.

I did buy from an AD, but no mention of this rule. So, on Tuesday I woke up and advanced the date from the 29th to the 1st. Should I not have done that? Also, I don't know what a quickset is, assuming this is only on a chronograph? One last question, apologies if this sounds silly, if this "rule" is serious, why is not mentioned in the owner's manual? Thanks again.

As we have long ago established, it's not just the B01 movement that it doesn't apply to.

No idea why it's not in the manual, it's in every manual that I have ever had where it applied. Quick set date is the ability to advance the date on its own (first crown pull out) and is on your 2824-2 based caliber 17 Seawolf.

As long as you didn't wake up until after 3am on the 29th you will be fine.

The quick set feature is adjusting the date while the watch continues to keep time; you do it with the crown pulled out to the first stop after unscrewing it. In contrast, you can advance the time on your watch past midnight and change the date that way. That's the safe way to do it if you're in the danger zone. The quick set applies to any watch with a date feature that can be set independently of the time, regardless of whether or not the watch is a chronograph.

The danger zone is only between 8pm and 3am as it shows on your watch. If you adjust the date at any time outside of this zone, you're fine. Thus, adjusting your date yesterday was fine, assuming it was after 3am, and that's the time that showed on your watch. Remember, your watch doesn't know what the real time is; it only knows what time it's showing. So that's the time you have to go by when taking this rule into account. (Also note: if your watch stops between 8 and 3, you won't know if that's between 8pm and 3am, or 8am and 3pm. Move the hands forward until after 12:00; if the date doesn't change, then you know that's noon, and not midnight. Do not adjust the date just assuming you're not in the danger zone. You could be without knowing it.)

The rule is quite serious. You can damage the gears that move the date wheel and actually cause the date wheel to stop advancing. Repair can be costly, and technically isn't covered under your warranty, since it's a result of your misuse, rather than manufacture defect. BUSA won't typically deny coverage unless you admit to causing the damage. I don't know why it's not stated in your manual. It is in mine, quite explicitly.

Finally, be aware that the rule also applies to moving the hands counter-clockwise during the danger zone, as well.

Thanks for all the responses. A very quick education on my part, much appreciated. I'm going to have to double check my manual. I know I read it cover to cover, but don't recall this particular topic. In any event, what I've concluded is that the safest route for changing the date is to advance the hours until I reach the desired date. I'm going to forget about the quick set feature altogether, since by advancing the hours instead of the date, there shouldn't need to be any consideration of what time the watch is actually showing.

You'll still want to distinguish between midnight and noon, so the date changes at the right time.

I was telling my wife that I was needing to wait till tomorrow to change the date on my SA since it is after 8 pm, and her reply was what time zone does this rule apply to since it is a Swiss watch.

Even safer then forgetting the quick date adjust.........just stay up til 3 AM and take care of it then. Why take chances?
