A follow up on this, so i took it to my reseller here and i received a new clasp that works flawless now 🙂 It took about 2 weeks from me handing it over to getting the watch back. I got to keep the old clasp too!

Also, I took the old clasp apart today and found that there was some kind of rubber/glue residue on the 2 metal prods that normally should catch the ratched teeth, i cleaned that off and voila.. i now have a spare working clasp!

Ah, i need to get it to Sweden again then, i will call the reseller later today and see what they recommend.

I wonder if the spring inside the ratchet might be to weak or something but it is really annoying when it changes size with bare minimum pressure on it. But its nice to see there is a fix for it, otherwise i would probably have sold it soon :)

Hi! Did you get this solved? My Certina also has this exact same issue (same watch as you have) And is about 1 month old, been doing it since day one.

I have a suspicion that the teeth inside the clasp isnt sharp or big enough or something..

I noticed that our watches seems to have teeth on both sides also, whilst @AussieWatchGuy only has teeth on one side, maybe an updated clasp?

Edit: nevermind, i saw the teeth now.. need to get glasses :D
