Will this hurt my watch?

[snyde]

I have a 14000 Air King that runs +8 sec / day. I find myself pulling the crown when I wake up and then starting it again 8 seconds later.

Is this bad for the movement in anyway?

I am dealing with the financial markets all day at work and keeping accurate time is extremely important to me.
Used to wear a quartz watch for this reason but I fell in love with automatic movement. Can't go back now!

No, but screwing and unscrewing the crown daily will invite the risk of cross-threading. 8 seconds a day for a non COSC movement isn't awful at all. The cal 3000 movement can be regulated to COSC spec so why not get it serviced?

It is not bad for your movement, it is bad for your stem and threads on your stem and crown.

If 8 seconds a day is an issue for you, you need to buy a quartz watch.

A watch that is consistently 8 seconds per day fast is very reliable and consistent. No mechanical watch is going to be entirely accurate to the split second day after day. Rolex tolerence is -4 to +6 seconds per day for an Air King. That represents a daily accuracy of 99.999%. If you need more accurate buy something electronic.

Alternatively, you may find you can regulate the watch by placing it crown up or crown down, or in a different position overnight, so that the few seconds it gains during the day can be countered overnight by leaving it in a different position that will slow down the movement a few seconds. Many do this to make a watch a true +/- zero seconds per day.

Or as suggested get it serviced/adjusted by a watchmaker.

I actually didn't know that about the cal 3000 movement!
I'll have to do some research and think about getting it regulated.
What year is your AirKing? Mine is a 1991 blue dial.

I didn't think about the stem and threads because the process of pulling the crown is seamless. I understand its moving parts on the watch which is added stress, but is it really frowned upon?

Mine is a 1985 5500 cal 1520 movement. At 8 seconds a day, you're right where you should be, but you're going to spend good money to find those 2 seconds. Only 2 seconds out of COSC on a non COSC movement, some folks would love to have accuracy like that

[snyde]

That does put things into perspective for me, and never mind those 2 seconds ;-)
Thanks guys!

8 seconds....so less than 1 minute per week. I cant imagine you are doing transactions in fractions of a minute, and if you are Im sure you watch the countdown for the closing bells.
Just reset once per week, no need to do it daily.

[brandrea]

Try regulating it yourself first .

My 5513 with 1520 movement runs consistently at + 3 seconds a daY.

[AK797]

I would leave it but if it bothers you then self-regulate or have it regulated.

Indeed all valid points ! Many thanks :-)

[HiloBeMagical]

Your watch runs 8 seconds fast per day? Set it on the first of each month.
The farther into the month you get, the more on time you'll be. Ta-DAH!

Thanks for that!

[crowncollection]

The watch is out of COSC.

Have it regulated, but I agree with others. If your watch has to be correct to the second for your work, you'd be better served wearing a quartz watch, which is not as demeaning as some would suggest.

Alternatively, you could use http://time.is/ on your phone for work.

U need a Casio. Lol

[azguy]

Just re-set it once a week, is a few seconds going to make you late for an appt

I honestly don't know WHY everyone makes a fuss about unscrewing/screwing in the crown, setting every day, etc. Geez - I've been diving since I was SEVEN years old (I'll be 60 in 19 days), and have owned dive watches since then. I still HAVE my very first dive watch - I'll bet that crown has been unscrewed/screwed in 10K+ times! It's been serviced TWICE since 1964...

I've owned a dozen Rolex Subs, including two 6538 Big Crowns, a 5508, a 5512, and a 5513 that I bought new in 1978 and sold to a friend of mine 3 years ago - original tube, crown, and tube gasket - I bet that crown's been unscrewed/screwed in over a thousand times - been on at least a hundred dives with NO water intrusion...

Sorry for the rant - it's a well-built TOOL watch - USE the damned thing! Now pardon me while I unscrew the crown on my '07 14060 COSC ND and "regulate it" to be spot on today, then I'll worry about something ELSE!
