dahar90's Patek Philippe Ref. 3445, a cherished family heirloom, presents a common dilemma for collectors of vintage timepieces: the decision to service a watch that appears to be running perfectly. This thread explores the community's insights on balancing preservation with necessary maintenance, particularly after an accidental drop. Readers will benefit from the collective wisdom on Patek Philippe's service protocols and the nuances of vintage watch care.

Hi All,

I’ve got a 3445 Calatrava in full 18k yellow gold (band and case) handed down from my grandfather. He bought it circa 1970 and was his daily.

He would have worn it till his passing in 1997 and was sitting in a drawer until 2018. 

I don’t think it’s ever been serviced according to my father. Since having it polished, it keeps time perfectly and there are no apparent issues.

A few days ago I was putting the watch on (horrible clip) and the watch fell 3 feet and landed on the crown. Unfortunately I cracked the plexi glass case. 

I called Patek and they said they can fix it (replace) for 300CHF which I think is actually pretty reasonable.

I was speaking to the watchmaker in Geneva and he mentioned I should also have it serviced. He said this would take 6-12 months due to the complexity and the fact it is an older model and not many can work on it.

My question is - should I have it serviced? My concern is that once they touch it, something will screw up. It’s been perfect to date never have been serviced. I’m curious for your thoughts. The quote was 2000CHF to service.

Thanks so much! 














About the Patek Philippe Calatrava Ref. 3445

The Patek Philippe reference 3445, introduced in 1961, marked a significant development as the brand's first serially produced self-winding, waterproof wristwatch featuring a date complication. This reference was a cornerstone in Patek Philippe's offerings, providing a robust and practical timepiece for daily wear while maintaining the brand's commitment to horological excellence. Its introduction represented an important step in integrating automatic movements and water resistance into their standard production models.

This reference typically features a 35mm case, often crafted from 18k yellow gold, though other precious metals were also used. It is powered by the Patek Philippe caliber 27-460 M, an automatic movement known for its reliability and precision. The watch is fitted with a sapphire crystal, contributing to its durability and legibility. The water resistance rating for this model is 30 meters, suitable for protection against splashes.

The reference 3445 appeals to collectors seeking a historically important Patek Philippe timepiece that combines technical innovation with classic design. Its role as the first serially produced automatic date watch with water resistance makes it a notable piece in the brand's heritage. Variants of this reference exist, primarily differing in dial finishes and case materials, offering collectors a range of options within this foundational model.

your best option. It should be cleaned and serviced. Do not let them polish it.

Thanks! So it should be serviced? This won’t just open up a can of worms? Why do you suggest to not let them polish it?

In general, collectors prefer to avoid polishing because it removes a small amount of the original metal layer and in order to maintain the original “integrity”/condition of a watch…unless it is in really bad shape and needs the polishing. In the case of your watch, the case looks great already, so no need for another polishing. Besides that, as long as the servicing is going to be done by the right people/person at the manufacturer, then there is little chance of ‘opening a can of worms’. Plus,

If you can't trust them to fix it, who else can. Don't worry too much. As for polishing, i'm still trying to get my head around the prevalent advice against doing so for myriad reasons. End of the day, if you do not intend to sell the watch and you feel having it polished makes you happier, just go ahead.

Serviced a40’s Calatrava by Patek. Putting costs aside. They will give you detailed quotation, and you can pick what you want (like polish or not). The will fix it with spec parts, like correct crown and glass, even gold spring bars. AND you will get a Patek document, like invoice, with all the details. Send it w/o the bracelet.

Thank you! This makes total sense and is like a gold ring…got it! I had the band slightly shortened (cut) a couple years ago and they polished it after they worked on it.
