Noisy A7750 rotor: what to do?

[prdubis]

Hi there,

My A7750 rotor is very noisy, I hear it rolling every time I move the wrist...

Anyone know how to solve that?

Thank you!

Even the gen is noisy...but not as noisy as the Asian version. The solution is proper servicing.

Look at the link on the noisy rotor in the Noob Guide linked in my signature.

It happen on ASIA ,

the main bearing is too low quality.

Even after having an A7750 properly serviced by "the man - Zigmeister" it was still naturally loud.

From Gisbert L. Brunner's fantastic article "The Fall and Rise of the Valjoux 7750" from the June-2008 issue of Watch Time:

"In addition, some wearers

are conscious of the sound the rotor

makes. It occurs because the large oscillating

weight with its heavy metal segment

can reach very high speeds when rotating

in its non-winding direction. The

sound is unavoidable, however, and

Thank you for your knowledge!

I've just sent my black theme for servicing, reluming and waterproofing! Hope service will help...

Will post pics as soon as I get it back!

Like Rosnik said...there is the issue of poor Asian quality. I've had some serviced where they came back silent, and others come back definitely quieter and smoother but not silent. This could be because of different factories making the movement and different levels of quality.

I was considering getting a Breitling Skyland... not a fan of loud watches though.

I've taken a little lube oil that I got from Ofrei and applied a little the ball bearings in the rotor with very good results..i just used a toothpick to the ball bearings in the rotor..gear lube .. I cannot remember the exact name of it.. comes in a small white bottle and is thick in it's consistency..

I had re same issue with the three FM kings I got. used the silicone lube that came with O/S's toolkit. The rotor became absolutely silent after that.

Funny thing is...my Skyland is one of the few watches I haven't had serviced, and it's one one of the quietest...funny that. Gotta love reps...
