The best thing to do is contact where you bought it or contact the manufacturer. I had a problem with a similar watch and the manufacturer helped me. :)

You may have a small leak in one of the lines. You would need a Garage to find out where usually.

Have you tried the manufacturer or local wants ads?

sometimes a tiny bit of dust and fluff can get between the small tension discs. Use a fine piece of cloth and carefully insert it between the discs and gently manipulate it to clean or dislodge any dust. Hope this helps :)

Much more information is needed. Do you mean it's not stitching? There are many, reasons for this, wrong size needle for the material, incorrect thread, incorrect tension stretch material vs, nonstretch, satin, and silks. So please send more info. :)

Have you removed the bobbin case itself to see if it has any thread or compacted fluff there? Also sometimes we forget to return the thread lever back after filling a bobbin. this lever blocks the handwheel from turning. If it is a metal bobbin case it may need just one or two drops of oil. Failing these things, you can turn the machine upside down and remove the bottom plate to see if any of the screws that move the handwheel mechanism have tightened over the years. Otherwise, I guess it's a repair job. Hope this helps. :)

Please contact the manufacturer.

To be repaired would depend on the size of the holes. It would have to be repaired with the same material. Better contact Patagonia, or if you are a lady you could cover the holes with a flower patch or in fact any patches that please you and satifies how it looks.

You can do this yourself if careful by using an iron on patch from the inside. For a really professional of course send it back to Patagonia but it will be expensive.

It is possible to do this yourself if you sew. If not many dry cleaners will repair garments, or be able to tell you who does. :)
