The Breitling Watch Source Forums

Under Preparing The Watch For Use in the manual, it says wind watch by 40 clockwise turns of the crown.

How often does this have to be done - only when it unwinds itself (eg from not wearing for awhile)? I thought it is self-winding?

How long does it take to unwind if it is not worn?

What does the "mechanism" do between 8pm and 3am?

Caliber 19 is selfwinding and if you wear your wach daily, you don't need to wind it manually after initial 40 turns. It has 42 hours of power reserve.It's between 10pm and 2am (8pm and 3am was taken just in case), mechanisam starts to change the date (till midnight). After changing the date, wheels teeth are still in interaction (till 2am), so it's not recomanded to change time and use quick date set function than. I'm sure that somebody more fluent in English will explain it much better.

No need at all, bnewbie - I couldn't explain it any better than you did!

Thank you but I doubt that somehow.

Just a thought -

If a movement has a 40 hr reserve and it is left off overnight (say 8 hrs a night) will the reserve run down after 5 days?

When I'm wearing my Monty I wind it every couple of days - I always thought that was right.

This is a complicated subject - one which is brought up time and time again.

Anyone know what the big B say?

No, because you pump that reserve during daily 16 hours.

Thanks for your response bnewbie:

To clarify the question asked above, there is no need to wind the watch if you wear it every day. The only time you need to wind the 40 times is when the spring power dissipates, i.e. when you don't wear the watch for 42 hours as you state. This is why some people with many mechanical watches buy watch-winders. Since my watch worked when I bought it I assume the store would it for me.

I am slightly unclear on the following: Why wind it 40 times? If I am wearing it, won't it wind itself automatically? Also, am I to wind it 40 times every time the power reserve runs out?

By the way, your English is fine!

OK bnewbie

I'm not being deliberately stupid but maybe someone can solve the following:

When you wind for the recommended amount of turn (dependent on motor) it will offer some resistance when you reach the fully wound/charged capacity.

Why then, if you wear your watch then for say 16 hrs, or so, a day is there no (or less) resistance to winding again after 2 or 3 days?

I have not worn my Monty for more than a couple of days at a time so don't have experience of living with an automatic - day in day out - week after week.

Do they just keep going if worn enough - if you just used the same watch all the time?

If you wear an automatic all the time you never need to think about winding it. Sometimes I can go a whole day without a watch on (OK, it is a rare thing, but it happens), and when I put my B on some 24-30 hours later I dont need to wind it. It gets powered up gradually from being on my wrist...
So in conclusion; this is really not an issue if you wear the watch every day, or even a bit less.

My wife only wears her automatic for around 48 hours a week and she never needs to wind hers - although she's usually fairly active with it on which will wind it quicker.

Of course the flip side is that there is no danger of overwinding an automatic so no real downside to winding.

I've noticed real resistance only with manually wind watches, autos become a little tight after 40+ turns but not resistant. As Roff stated, you don't have to worry because it can't be overwound.

Because main spring is not so tight like when you gave it 40 turns. It all depends on how active you are during a day.

You are welcome. 40 times is initial to gave the main spring full tension and only after that your watch has a full power reserve. Some days when you are less active power reserve lessens a bit (if that's a few days in a row, you can notice that you watch loses a sec or two more than usual).
On the days when you're the most active your power reserve is on maximum.

Right - got it.

Makes sense, just never had a full explanation although the subject has come up a few times.

Thanks guys.

I going to start wearing the Monty a bit more now. No point in having it and keeping it for rare special occasions.

I'm actually wearing my Monty everyday and finding it is actually more versatile than I thought it would be. Goes well with a suit and dressing down...although not with t-shirt and gym shorts!

But, if you get the right t-shirt and the right type of jeans, it will go well with that too!
