Which second Garmin watch?

I also think that it is designed to be used exhaustively (or should be), but as every thing, it isn't 100% and long time "wear proof". So, this is why i think it need some "rest".

I had a similar idea, while waiting for an affordable used Fenix 5X to show up one day, and planning to sell the FR935 then. I tried to keep the Forerunner looking really good, used an Epix for wearing on weekends and for any activities that I didn't really 'need' the FR935 functionality for. Just to minimize the risk of scratches and signs of wear. Of course there was/is a screen protector on the FR935. But despite all that, the bezel of the FR935 doesn't look all that great anymore (shiny patches), the buttons feel odd and squishy, all the dark colored quickfit bands have shiny and 'bald' spots. I gave up and wear the Forerunner all day, every day, for everything.

We ( my wife and I) have only ever had one Garmin at a time each. Granted we only use them for sport, but we get around 700 hrs a year of active use. No complaints about how these 935s are going. We swim, bike, and run (pool and sea, off road and road, mtb and trail) and still they go on. I know there have been comments about the buttons going 'soft', but if ours changed from initial use, we've not noticed it. Perhaps we don't care? They still work. Like anything, you might be able to extend it's life by reducing the amount of time you use it. However, there's usually something newer come along that's advancing the technology long before ours have worn out.

That is exactly why I want to keep my watch to looking as new, so it'll get a good price by the time it gets sold, in order to upgrade to that new advancement.

So I'm not quite sure why your 935 needs a "rest".

I agree with you. I wear my 935 24/7, 365 days a year. It basically only comes off for charging and once while attending a wedding this summer. Anyway, I beat the hell out of mine. I've gone through 5 screen protectors, took a nice spill when a jackass ran me off the road cycling, use it for both OW and pool swimming and shower with it daily. I'm not having the issues with the barometer or OW GPS tracks others are seeing. Some say to prevent problems, keep the watch "vanilla". I don't have issues with that either. I currently have 4 data fields, 6 apps and 11 widgets from the IQ store on my watch. The only wear I have is a small smooth patch worn on the bottom of the strap. I used my 235 the same way and it's still going strong. I don't see any reason for my 935 to be any different and it definitely doesn't need, or will be getting a rest. All that said, watch the damn thing die tomorrow.

watch the damn thing die tomorrow.

LOL! Many a word like these, have been spoken in jest only for them too...

..and especially in the case of sudden device death, having a second watch is a really good thing! ;-)

The question really is: shouldn't na expensive watch that is designed for triathlon, withstand intensive training?
Yes it should!
But it seems, in some cases, that it is not guaranteed.

My watch came with a 1 year guarantee with the option to purchase an additional year through the seller. I've read some (maybe all) in Europe come with 2 year guarantees. If they fail for one reason or another during that time, get it replaced or repaired. It's your right. Should I only use my 935 for 10 months and "rest" it 2 months in the hope that it will last longer than my 12 guarantee? Do you "rest" your television, refrigerator, or washing machine by buying a second appliance in the hope the original will last longer? It's clear from your post in this thread that you've read the Garmin forums and have internet access. You've stated what features you want in a second device and what features aren't that important. You've done your homework. Many have reported issues with their 935. Many have stated they don't have these issues. You've decided there's a chance that your 935 will fail, so it needs a rest. You've come to this conclusion by yourself, but you need assistance on what 2nd device you should get from a bunch of strangers on this forum? Buy whatever you want. Buy a second 935. You won't be giving up anything and you can rotate them how ever you wish. Problem solved.

But it seems, in some cases, that it is not guaranteed.

There is a warranty on the purchase for a reason. There are no guarantees in life. There is a failure rate with all purchases. Even with a 1 yr warranty, I would still expect to get more than that. In fact, I would expect any definition of reasonable and fair use to extend well beyond the warranty period.

Buy whatever you want. Buy a second 935. You won't be giving up anything and you can rotate them how ever you wish. Problem solved.
