IWC 80110

Hello fellow IWC lovers.

I recently bought an IWC Vintage Ingenieur 323301 and I love it.
The finishing and quality on the watch is great.

I bought it second hand and the previous owner said it was serviced in April 2016. I have visited the jeweler where the was has been serviced and they confirmed it.

But last week I visited my watchmaker for a service of my Speedmaster and asked him to put my IWC on a timegrapher and see how the watch works.
The watch runs good and didn't lose any time but the amplitude was around 240 while fully wound.

Is it normal for IWC 80110 movement to have this low amplitude?
Or has the service been done not correctly.

Thank you for reading and please excuse my bad English.

Welcome Adam
Congrats on the VC Ingenieur - it's a fantastic watch and a real beauty too!!

The good news is that it's not loosing time, although 240 does seem to be a low amplitude. TBH, I don't know what the specified amplitude should be, or if it should be within the usual 270 to 315deg.

Having been serviced recently, I don't think the pivot is dry, probably lunricated with oil that was too thick. Wear it for some me time, see how it performs (it might run in) and then have it serviced by an IWC Authorised Dealer in a few years. This will certainly return it to specification.

Two Questions to Clarify
1. Was it consistently 240 degrees in all positions? Or was there a vast variance from one position to another??
2. How did you determine fully wound?
Should be at least 20 to 30 turns of the crown.

It's 240 in most of the positions but it varies between 230 and 250.
And I have wound the crown until I heard the clicking noise, which stops it from winding up I guess?

And I have also noticed the "ding" noise while changing the date manualy.
It sounds cool, but is it healthy ? I haven't heard this noise in any other watch :)
