GS, a dedicated Patek Philippe collector, shares a concerning experience regarding a scratch on the case back of his unpolished Patek Philippe Ref. 5738 Ellipse during a service. His detailed account, supported by photographic evidence from different stages of the service process, raises important questions about quality control and accountability within luxury watch service centers. This thread explores the community's advice on how to address such issues while preserving the watch's original condition.


The Patek Philippe Golden Ellipse reference 5738 represents the white gold iteration of the model with a blue dial configuration. This reference distinguishes itself within the Golden Ellipse range through its precious metal case construction and contrasting dial treatment, positioning it among Patek Philippe's dress watch offerings.
The 5738 features an 18k white gold case measuring 34.5 x 39.5 mm with polished bezel treatment and sapphire crystal protection. The automatic caliber 240 movement provides 48 hours of power reserve, housed within a case offering 30 meters of water resistance. The blue dial is paired with a leather strap configuration.
This reference appeals to collectors seeking a precious metal Golden Ellipse with distinctive dial color. In production since 2018, the 5738 offers an alternative to traditional dress watch proportions while maintaining the model's characteristic case shape. The white gold construction and blue dial combination provides collectors with a specific material and aesthetic variant within the Golden Ellipse lineup.
I would suggest you write to the Patek distributor in your region with a cc to your AD. Patek is responsible to this type of matters based on my own experience. Let us know what you decide to do and best of luck !
Originally, the back was handpolished to become "new." The worker could've finished it a micron thinner or thicker, as is done with each. In this particular case - ya got lucky - its a flat surface, and the scratch doesn't look too deep. I think I'd let them brush it out for you, using the same machine and setup as was done to make it "new" - and simply chalk it up to being within the variances of a handfinished product, even if there's a touch more to the story than you'd prefer. Good luck!
will result in any of the negatives of having a polished watch. If it bothers you, I'd just have Patek remove the scratch and move on.
resurfacing done by the manufacturer. I would let them correct it.
...replace the back...
I wouldn't accept a polish even though it is superficial. Read "Service" under PP Values; they will have to change the case back as this is clearly their fault.
