Cracks on Forerunner 645 Music body

Hello garmin users,

I just wanted to highlight some issues I recently discovered on my black645M. I have it since March and had no issues till last week.

When I removed it after a run, the band detached itself and that's when I discovered that the body was cracked where the band pin inserts into the body of the watch
What's worse (if that's possible) is that after inspecting the entire body, I've found that the 3 other holes for the pin were also starting to crack.

I am very cautious with my watch that has never been shocked in any manner. I do switch bands sometimes (official garmin bands) and I'm always careful when doing so.
I don't understand how this piece can be so fragile after only 9 months of not so heavy use, I'm wearing it daily at work and I've been running with it only around 40 times (no swimming).

I've just returned it to the shop as it is still under warranty and I hope that Garmin won't make any trouble to replace it but I'm now afraid that such an expensive piece of gear may not last that long finally... My previous Vivoactive HR died after 9 months also but this time it was after a one sessions at a swimming pool so the water proofing was probably faulty that time.
I can't afford a Fenix Chronos that is full metal nor want to carry such a heavy watch, the F645M is the perfect size for me and has the functions I want in a watch...

I'm adding some pictures of the cracks so you can see what it looks like.

I've seen similar posts for other models but nothing so far for this watch. Has anyone faced that already? ciq.forums.garmin.com/.../1431516.png ciq.forums.garmin.com/.../1431517.jpg
  • After contacting Garmin Support they recognized the failure with the watch band body issues. They said they have extended warranty period for this particular issue and have redesigned  the body to prevent braking. My watch is on its way to Garmin now to be exchange with the new design with a prepaid RMA. They did say it could take a few weeks due to new design  product availability.  As long as they take care of the issue I'll be happy. 

  • BTW, this is USA garmin support.

  • When the replacement arrives, can you please post a couple of photos? I have already broken 2, the second I have not even replaced (just a small crack) but reinforced with a TPU cover from amazon for only 6 euros, now my wife uses it and it holds up very well.

  • Thanks for the update gcalhoun85. I’m really hoping that Garmin Australia are as forthcoming in acknowledging that there are issues with the design. I hope for a similar outcome where my broken watch can be replaced with a watch with the new redesigned watch body and not a refurbished unit that may see the same problem present again in the future.

    So far after speaking to Garmin Australia Support at 11:00am on Tuesday morning and replying their email with the requested details within five minutes of receipt, it’s now 6:00pm on Friday evening and I haven’t heard anything back.

  •  I received the replacement watch.  My wife sent me a picture of it since I am currently traveling.  Garmin told me this is a redesign, but I'm not seeing any physical changes by looking at it. I'm glad Garmin replaced it and really hopping there is an improvement.  Time will tell. Here’s a picture. 

  • No photos are seen

  • As an update, Garmin Australia offered a replacement of the damaged unit with a factory refurbished unit. I must acknowledge that once initial contact was made were very helpful and the warranty process is straight forward. At the time however there were no refurbished units in stock and replacement time was estimated to be two months. I contacted Garmin again because I felt that 2 months was a long time to wait for replacement and they offered to replace with a different watch from the Forerunner line or provide/facilitate a refund through the original seller. I decided for a refund and purchased a Fenix 6S which was on sale at a heavily discounted price. I’m happy with the outcome.

  • My watch did the same thing while changing the band. I see eBay has replacement backs for the watch.  Do you think this would work to fix it? Only $20-$30.

  • My watch just broke as above during a watch band change.  I see eBay has replacement backs for $20-30.  Do you think this would work?

I was able to repair my car handle from the door which broke into two pieces during the winter. Once the paste is dry it became one part with the body part.
