I feel predicting service intervals for watches, solely on the life of "watch oil", is too absolute. There are many watch oils used in watch repair all with varied properties. On top of the extensive list of oils are contributing factors to service life. ...

thanks for the amazing work, this is a very helpful and informative post. Welcome here ! Jeff

Indeed, when we speak about a perfect finish, we should avoid your macro pics..LOL Seriously a big thank for your post, as the question of servicing a watch is a recurrent question, and now, we know and understand why and when the service is to be made. B...

All that being said, I have a Maual wind Patek Philippe 5004 Sealed In Plastic Sealed In Box in the Safe Depost box going on 2 years obviously untouched, unwound etc. I would assume temperature is ideal as we are in Coastal California. Does a watch like t...  

If you are keeping watches for investment, are they remaining in the sealed never opened plastic? If so, I do not think they need to be serviced. If they are being used this is another issue. If you get your watches out of the safety deposit box and wind ...

Very kind of you to share your knowledge with us - Thank you!

Fantastic article!! Great pictures! somon

Thank You and I had a good laugh when I read: " because watchmakers are over paid grease monkeys. The truth in this can be found by the luxurious lifestyle bench watchmakers enjoy. Only champagne and caviar at morning tea for me!" S
