Patek Philippe

Well look I do watch and try and fly back chronograph. The shopkeeper tells me to look 'cause he was always afraid to do this operation. why watch can 'break! I remain stunned.

I try and once you know that the second hand does not return a perfect 12 hours. I try again and it works then I leave aside and look at the total clock. Shopkeeper tells me that he hopes that it is all  and that the maximum change with a new one with the difference money. I take clock go away. taxy load fine watch and try and fly back chrono functions.

Amazing! Disappointment! Angry! The seconds hand did not return for 12 hours. Both with Auto Start Stop function that chrono fly back!

I call immediately shopkeeper who says to me, but are you sure that there is fly back on 5980! wanted to be clever? tells me to go to him by his coach, but I can not be present?

arrival tells me that we go technician then takes me to his office I laugh money! 5 minutes later he calls me famous engineer who tells me that I'm not able shiacciare good chrono buttons and fly back!

let it be my anger and other sellers so why should not exist! I then sent the message telling me that he was sorry not to know who was present flyback function!

but its perfect watch as his coach says Patek very professional! another joke not to use other words. I'm not sure that this seller will see ever again but apart from this ugly story What do you think of this defect? I read that some models had recognized patek 5980 issue of regulation of the keys. could someone help me understand better level technique. 

thanks and sorry for my english

Schiacciare is push

early 5980 had problems and this is one example?

After reading your post, I was not able to comprehend it.  I am sure you made an effort to make your post as comprehensible as possible.  

I assume you bought the watch.  

The rule is when buying used to buy from a store or an individual you trust.  

Good luck Jaacob!  

The watch in question seem to have a issue with the correct return-to-zero/flyback function of the chronograph hands. It appears to me that it sometime returns perfectly but sometimes not, and the seller seems to agree to a refund if the problem persist. Which it does.

Jaacob returns the watch to the shop and was told the he did not press the buttons correctly. Jaacob is now upset because of the defect in the watch and the behaviour of the shop.

Provided my understanding is correct, these are two different issues, actually three:

First (this could be a language/translation issue), Jaacob seems to expect a Flyback function on the Patek 5980 which (as far as I know) is not there. IF the 5980 returns to zero without having to stop the chronograph first then I think the watch is indeed defective, most likely due to mishandling by the previous owner. 

Second, as Nico already mentioned the watch is used. This means that slight misalignments/defects/signs of use can be there, even if not immediately detectable. It could have well been that the watch worked perfectly when the shop acquired it, but then started to malfunction once in Jaacob's hands. If asked about advice on a used watch I always recommend to add the costs of a service to the final price as a measure of the real purchase costs.

Third, there are the promises of the seller and how he/she stands to them. This is something I we don't know for sure as this is a private agreement between you two, and I think this is barely a topic here.

Thanks,

Magnus

To check if the chrono is a flyback, all you have to do is - When the chrono is running, press the reset pusher ( the lower one closer to the 4 O clocl position) and if the seconds hand jumps back to zero (60) and restarts instantly again without the need to press the start-button ( the pusher at 10 O clock) , it is a flyback.

The Patek catalog ( refer Page 164/165 of Collection 2008/09 for 5980 ) and Page 70/71 which speak of 5960 donot have any reference to flyback feature. for caliber 28-520 .  However where the seconds hand is used as a continuous running seconds ( i.e. chrono is not engaged), then you can start the chrono ( change from timekeeping mode to chrono mode) without the zero reset step ( i.e. stop, start). So I would not actually call this a flyback in effect.
