Navitimer fighter's movement problem?

[Ridler]

I have been wanting a nice Navitimer rep for quite some time now and when I became a member here the first thing I studied was Andreww's Guide to Breitling Navitimers.

I quite quickly decided that the Fighter's edition was the one for me, I didnt really care too much about the flaws I just loved the way it looked.

After a few mails back and forth with Hont the Fighter's edition was on it's way to Sweden. It took about 10 days before I could run to the nearest post office and fetch my shining new watch.

But (!!) as I unpacked it and got it out of it's bubble-wrap I hear a very odd sound coming from the watch. It was as if there was a ball rolling around inside the watch as I tilted it back and forth and from side to side to admire my new precious.
I do not know where this sound is coming from and I can only guess that it is the winding-mechanism that is emitting it.
I am naturally very disapointed but I know Hont is going to supply me with a new watch as soon as I can get a hold of him after the Chinese NY.

I was wondering though if anyone here has had any similar experience and might have an idea what the problem with my beauty is.

Like I said the watch makes a sound as if something is spinning around inside it, almost like a ball bearing when I tilt my wrist. The sound is very noticable and people are asking me why my watch is making such funny noises. You can literally hear the winding-mechanism (I'm guessing) spin around inside and grind away.

Thankful for any help, input and/or suggestions.

Oh and btw - maybe I am a complete moron but the 6 o'clock subdial does not move at all. I am not sure what it is supposed to do but no pushing of any buttons will make it move.

Is it a 21j or a 7750 chrono movement?

If it is a 21j the winding mechanism on them sometime can be loud. Especially if you are in a quiet place and move youw watch around you can hear the rotor spin.

i pmed you

I was told when I bought the watch that is has an Asian 7750 movement.

There is no way I could tell the difference without opening the watch I guess. Any suggestions on how to open it up?

And the noise is not just noticable when in a quiet room it's a real loud obnoxious sound that can be heard in more or less any environment. I noticed it earlier today in the subway. Though I am ofcourse, subcontuiously trying to hear the noise. Hoping it will have disapeared.

to open it make a ball of double-sided big like a tennis ball. and you will open it wihout scratch

So if I make a large ball out of double-sided tape and attach that to the crown and just pull it off? No need to unscrew it in any kind of way?

This sounds like a dangerous plan to me, a happy amateur trying to fiddle with a watch by using a ball of tape.

 

[MEYER8888]

I speak to open the case back!!!!!
for the crown you muss push a little puscher on the mvt

 

[COLDI]

Not to the crown!

Use the ball of tape to the case back. This is the piece under the watch that has contact with your wrist.

Do not do that to the crown!

 

[Ridler]

lol. I meant the case back, I'm sorry. Doing that to the crown would have been interesting to say the least

 

[COLDI]

So are you just trying to open the caseback to determine movement or to see if anything has come loose/unscrewed?

Bc if you arejust removing it to see the movement then you should be able to tell just the chrono hand and how the subdials move

 

[Ridler]

I am more or less certain that the movement is a Asia 7750. I payed some $200++ for it and I trust Hont as a dealer.

I would try and open it to see if something has come unscrewed inside. I am not sure I will be able to do anything about it even if I find the problem. I will probably be better off returning the watch and live with the noise until the CNY has passed. :/

First, the subdial at 6 is the hours for the chrono. Moves very slowly.

I have a Navi 7750 as well. The rotors can be quite noisy at times. If you get the back off, put a (very) tiny amount of axle grease in the bearings on the rotor. Makes it a lot quieter.

You might also find that the bezel assembly can be noisy as well. Common problem with Navi's as well (do a search & you'll see). You can tighten it up, but it involves taking the watch apart & removing the crystal. Not an easy fix.

Thanks for the input mate. The 6 subdial does not move at all, it sits pointing at 12 all the time.
I will open it up and grease it a little bit, but only to make it wearable until Hont comes back from his CNY leave. At that point I will be sending it back for him to replace.

I love the watch and I really don't want to wait for 14-20 days while my old and new watches are shipping, but what can you do. Except buy something else to wear from eurotimez while waiting

Btw, where would I be able to get axle grease? Is it some special kind that I need to buy from a web-based supplier, or could I find it at my local jeweler/watchmaker?

The noice from you watch comes from the rotor and the problem is, that the rotor needs some oil. Be very careful with the grease, if you have a watchmaker working on reps he could help you. I assume that you started the stop watch when you look at the counter at 6? :lol: :lol: :lol: :lol: Let it run for 24h!

I would not do so much with the watch, sometimes you can get in trouble when you send a watch back which has marks on the back from opening or you could easy over oil it.

Once the rotor is placed in position you can put a couple of very small drops of 9010 lubricant into the ball bearings on the rotor. Don't want to use too much so it won't splatter.

I have started the stop watch but I have not had it running for more than 5 minutes or so, does the 6 subdial count the hours of the stop watch? If so it is only natural that it has not moved since I have not used the stop wtsch very much at all.

I will try and find a watchmaker some day soon that is willing to put a drop of oil or two in my watch, if I cannot I'll try opening it up myself. All I need is the lube itself, I wonder where that could be found.

Thanks alot for the input.

Thanks alot mate, I will certainly try that out. The noise the watch is making atm is unbearable. I'll try and find a supplier of watch lube in Stockholm where I live, or I'll order some from http://www.tztoolshop.com

Ok, this is a wee bit embarrassing but the 6o'clock dial works just fine. I have now had the stopwatch running for over an hour and it has moved to show 1, it will most probably move to 2 in 30 mins or so.

Sorry about complaining over a watch that works without problem. I'm a total noob in this field and this is just another rookie mistake.

In other words, the watch works just fine. The only problem is the noise it is making and that is fairly easily fixed by lubricating the rotor.

Only 1 thing left to do - find and buy some 9010 lube, buy some double sided-tape and remove the bezel, apply a few very small drops of lubricant on the rotor. Everything will hopefully be just dandy after that.

Time to PM Rocketeer and get some double coated AR on the Navi. :lol:

There is no guarantee that the lube will take care of all the noise, but at least it's worth a shot and might help reduce it some. Good luck with it.
