Well I really hate to write this on the forum, BUT, the lack of support from Garmin have given me no choice. I purchased a Garmin D2 pilot watch for my son as a graduation present and within 2 years the watch enclosure is full of cracks and he is no longer able to wear the watch because the location where the strap mounts is broken off. The cracks are clearly a manufacturing defect as they are all over the place on the enclosure and Garmin will not help resolve this problem. Garmin support says we must pay $200 to get the watch refurbished. This is a $500 watch we are talking about here! I have had $20 watches that lasted me 10 years without problems it is sad to see that Garmin is not standing by their product better than this. As an Electronic Engineer who designs mobile products which are mounted in plastic enclosures, I can tell you that I have only seen this type of premature failure when a very poor grade of plastic is used or if the plastic is defective or contaminated. Yes "manufacturer's warranty" has expired, but I would not expect the enclosure to degrade within 2 years, and it's awful that Garmin thinks this is normal.
Technically the watch is good, but the enclosure sucks. So as much as I hate to say this, DO NOT BUY this watch unless you are willing to replace it within 2 years or pay an additional $200 for repairs within 2 years.
