Finding polar ft80 serial number

Not enough information. Is this a serial number and not a model number? All I was able to locate was a book via basic search. We elect how much time we spend on questions depending on the question. Sometimes it is not cost effective to the site of us to offer extensive research when minimum information provided.
good luck

Turn the watch over and look on the back of the watch near the wrist band. The serial number is the rather long set of numbers you will see there. You can't miss it. If you see what look like zeros or letter O's, they are zeros, not O's. I have the same watch, and that is your serial number.

probably there's a problem with the connection of the battery of your watch, that's why it turns off, second it might have a different size of battery that have been installed. or the battery is not properly installed. these are all the possible cause of your watch. i hope i had been helped you.

Serial numbers are generally on the back of the watch.

You may be able to find two or three numbers on the watch.

A case number, a movement number and a serial number.Alternatively you might find a style number (which in your case is 26B44) and a serial number.

Always look at the numbers on the old battery first and replace with the same. If you don't have the old battery then I would check with a local business that sells that watch. Sometimes you might find the battery number engraved on the case back. Hope this helps you,.good luck.

CE Marking (CE-Marking), is also called sometimes "CE Mark", as shown on the top of this page, is a mandatory mark for many (estimatively around 70%) of the products sold on the EFTA plus European Union (EU) market (total 28 countries) and it is often referred as the "Trade Passport to Europe" for non-EU products.

Polar's CE marking is CE0537. It is on all Polar products.

It is not the model number. The model number on monitors is printed on the back and is usually above and sometimes below the Polar stamp.

My model number was hard to read. It was nearly transparent. I did locate the manual for my model at:
