I have owned the Forerunner 405 for a year now and use it as my daily watch. The unit may be a bit big for the average user, however, my last watch was a Suunto Core so I am more than used to wearing a big watch.

This 405 has a lot of features and learning them all can seem overwhelming at first; But they are pretty intuitive and easy to understand if you spend some time with the watch.

The touch sensitive bezel allows you to scroll through the menus quickly, and adjust settings and specs on the fly.  The gps is fast and realiable and usually has an accuracy of 25 ft within 2 minutes. I've only hit a few spots in heavily wooded areas where gps aquisition took forever.

Battery life is on this watch is ok, but if you're using the gps you'll only get 6.5 - 7.5 hrs use with a full charge.

After owning the watch for 7 months the band holder broke where it connects to face under normal use. I had to send it in to Garmin. I called their 800 number and got the repair # and sent it in to them. A mere 5 days later I recieved what seemed to be a brand new 405 which has worked flawlessly ever since.

I am happy with the quality of the product, and of the timely turnaround from Garmin when something did go wrong with this watch.


I received mine for my 50th birthday 3 weeks ago.

I received mine for my 50th birthday 3 weeks ago. I run several miles 4+ days a week. I cannot clear prior runs from the totals, so each new run is cummulative of all my runs. I also can not get into the GPS functions of the unit any longer.

I emailed Garmin at the address in the Website more than a week ago and have not received a response.

I have spoken to other users, and they are not having the problem I am having.
