4.0 out of 5 stars Can wear everyday and tracks everything I need.
By Jared on September 9, 2016
If you're not into long reviews, the title of this review pretty much sums it up.

I've only had this watch for a week, but researched for months and knew exactly what features I was looking for.

First, my main use cases:
Running, swimming, cycling; but majority running. I used to do Triathlon's but just run and swim now mainly for health (and honestly stress relief). I wanted an activity tracker also and liked the idea of an optical heart rate sensor. Some limited smart watch functionality would be nice also. But definitely waterproof, built in GPS for running, and basic stop-watch functionality and something I could wear 24/7 as a daily watch also.

Watches I was considering:
Apple Watch, Forerunner 235, 735x, Fenix 3 HR, TomTom Mult-Sport Cardio, TomTom Spark, TomTom Spark+Music, Suunto Sparten, Ambit 3, etc. pretty much any of the GPS sport watches, ideally with the optical heart rate. I don't train hard or by heart rate really, and have had the chest straps in the past; just liked the idea of checking my resting heart rate at times and the activity tracker that comes on most of these sport watches.

Also, the Apple Watch was out, unless I went with the Waterfi version (waterproof version of it at @ $600). Of course, as I'm writing this, the new Series 2 Apple Watch was announced which is waterproof and has built in GPS. Which, may have altered my decision. I am an iPhone user, but in the end, regardless, I don't really care for the Apple Watch look and am glad I chose the 735xt.

I was able to visit a local REI and try on all the Garmin devices. I REALLY love the Fenix 3 HR and the style, but I have small wrists (6.5") and in the end, it was just too large. It wouldn't even fit under the cuff of my basic dress shirt, and didn't see myself wearing it to bed to take advantage of the sleep functionality. The TomTom's didn't really look like I could wear them every day as a watch. I did consider the TomTom Spark Cardio + Music as I liked the idea of not having to carry my phone. But then I really decided that I carry my phone not only for the music, but also in case of emergency.

The Garmin VivoActive HR had everything I wanted and cheaper, and even would have liked the idea of having golf (even though I haven't golfed in 10 years), but it's just darn ugly (IMO).

In the end, it really came down to the Garmin 235 vs 735xt. And whether the multi-sport and swimming functionality of the 735 was worth an extra $120. And so obviously I decided on the 735xt. Which I'm glad I did because it works awesome in the pool. For me it just came down to whether or not I wanted to track distance in the pool instead of just time and if that was worth $120.

Here's been my experience with it, using it for 7 days now.

- Looks OK to wear as an everyday watch
- Light (very light, which may also be somewhat of a con for some, see below)
- Pool Swim function counts distance and time (love how you just enter the pool size and it automatically keeps track of the distance, knowing when you make a turn)
- Connect IQ, this is where you can download watch faces, apps, widgets, data fields, etc. I've added a different watch face and use a stopwatch, timer app that I got from the IQ store. I use the stopwatch and timer a lot plus I've added a nice data field for running that shows HR (and color for zone), Pace, Cadence, Time, Distance all on the same screen
- Has some basic smart watch features. Email, calendar notifications, music controls for phone, etc. I really wanted these features in a watch, but have realized since wearing that I just turned them all off. Honestly, I get bugged enough with text and emails and don't need my watch distracting me also. So I just leave it on do-not disturb, as I do with my phone also when I'm running. Although the watch does have a user profile setting where you can set your sleep hours, so it sets the watch to do-not-disturb automatically during these times
- Garmin Connect Mobile App. Pretty good app, full of data and makes it easy to install and customize watch faces. Many watch faces allow you to customize them (how and what data is displayed, basic colors, etc.). It's pretty awesome

- Only con I can really think of is that the Garmin weather widget on the watch is not working for me. I did download a 3rd party weather widget, but it's not as dynamic as the Garmin version and only shows temp (hi/low) for the day. This is apparently common and happening with other users, so I'm pretty sure Garmin will have a firmware or software fix for this sometime soon. And I've tried about all the troubleshooting fixes I could find (e.g. location services, etc.) on the internet and Garmin forums.

Now about the form factor and weight. It is plastic. And this may be a be negative for some. I remember trying on the display model at REI and it felt like a toy. Of course I know these display versions are basically shells and not the real thing, but even the real thing feels a bit like a toy. So if you want a heavy, steel, metal or oversize watch, this probably isn't for you.

The last 2 watches I've worn were a G-Shock GW2310FB-1CR and for about 5 years a Lunimox Colormark Chrono (BO) every day. I like light watches. And for me, this Garmin 735xt is light, comfortable, and even though a bit "plastic" feeling... because I guess it is, it fits my use case perfectly. And if it ever breaks, I'm lucky enough to live about 30 minutes from Garmin's world headquarters and have heard good stories from friends who've taken their Garmin devices out there for service.

Battery Life
The specs say a bunch of different things, 14 hours in activity mode with GPS, 11 days in watch mode (activity tracking, smart notification, etc.) But here's what I've gotten from the first week. From a full charge and daily activity I went about 4 days and it was at 25%. But that's been with me fiddling with the watch a lot.

I did a full charge of the watch on a Sunday. Did 8 mile run on Monday, 1000 Meter Swim on Tuesday, 5 Mile Run on Wednesday, 1000 meter swim on Thursday and by Thursday evening it was about at 25% and in the evening it beeped and said "save power mode", which I wasn't quite sure what that was at the time so I went ahead and put it on the charger. Looking like it's about 10-12% per day with at least a 30-45 minute activity with GPS each day. Keep in mind I have activity tracking, continuous heart rate monitoring, and use the stopwatch and countdown timer a few times during the day also.

I hope this review helps. I researched (and obsessed) for months on which one of these to buy; weighing features style and price. Of course I'm biased now as I purchased the 735xt, but as of yet have no buyers remorse.

So why not 5 stars? I really never give anything 5 stars, but if the weather widget would have worked out of the box I probably would have.

1.0 out of 5 stars Heart Rate Sensor Completely Stopped Working on first one and screen stopped on second.
By S. arsenault on January 23, 2018
I received a refurbished model to replace the one with the broken heart rate monitor. That one has lasted FIVE months before the screen stopped functioning.

I have been using for 9 months. Interface is a bit klunky and takes some time to get used to. Intensity minutes measure is pure nonsense. Seems to randomly assign minutes between high and low intensity. But, the worst part is that after nine months the optical heart rate sensor has completely stopped working. I have not seen a flashing green light in quite some time. According the watch my pulse never goes above 101, ever. Even when other devices are coming back with numbers in the 150 range. On the other hand if I take the watch off it continues to register a heart rate. My bedroom dresser seems to have a higher average pulse rate than my kitchen island.

Getting through to customer service seems impossible. My message from yesterday has not gotten a response and the promised call back today has not happened.

I used to love Garmin products, this is my second forerunner 735 in a year where the glass has cracked. This will be the last watch I buy from garmin. The watch band loop broke and it fell off my arm to the ground and cracked. I thought garmin was a quality brand, very disappointed
