Omega Mark 40 3520.50 Service Advice

[Mechmovt]

Hello all,

 

I'm happy to be posting my first post here after reading some fantastic posts, and watching pretty much all of Mark's videos! 

 

I recently bought my self an Omega Mark 40 as a gift to myself for my upcoming 25th birthday (30th of Jan), and it is in desperate need of a service! 

 

I've noticed the chronograph hand is not lined up with the others, and I'm assuming this is just improper hand placement. I'm also planning to change the mainspring and possibly crown; should I look at replacing anything else? 

 

Can anyone advise me of anything that I should keep an eye out for to replace? Is there anything in particular that I should be cautious of when working on this movement, or any notorieties that require particular servicing attention? 

 

Than you all in advance!

You didn't say if you needed any technical information? So I found this service manual and a couple other updates. Then as a reminder getting Omega parts can be sometimes challenging to impossible.

Hi JohnR725,

 

Thank you very much for those resources; I had actually looked around with no luck so I really appreciate this!

Hi,

      You do not mention your skill level.  The Omega shown must be amongst the top 10 of watches.  It is very easy to cause very expensive damage if unsure of the correct methods to use,  I would only entrust such a watch to Mark Lovic.  Maybe you have been servicing chronographs for most of your life, in which case go ahead.

Thanks for the advice autowind. I haven't really worked on a chronometer before, but I have worked on many automatic watches. Although not something I'd take as a test subject, it's definitely a learning curve for me.

Cheers
