Garmin Forerunner 645 GPS with Wrist Band: The Smart Garmin Watch

The Garmin Forerunner 645 GPS Running Watch is one of the most innovative sports watches of today. This is because of the Garmin Pay feature that lets you buy the things that you will need outside.

Along with the Garmin Pay, it also features all the running and cycling metrics that you will need. These functions include the Ground Contact Time, Vertical Oscillation, Vertical Ratio, Cadence, and Stride Length.

In addition, it has a heart rate monitor, GPS mode, activity tracking mode, and a dedicated application.

Personally, I take this one as an all-inclusive type that can really help you with your training sessions. Although it is focused more on the running aspects, you can highly adjust the settings depending on the activity that you intend to do.

Timex Full Size Ironman Classic 30: A Fitness Watch for Men

The Timex Ironman Classic 30 is a watch that is designed mainly for fitness tracking. I included it here in my list because I find it as a great timepiece for simply tracking your training sessions.

The features of this one include a stopwatch with a 30-lap memory, a countdown timer, an alarm. Other than these, there are no further functions that you can use for your triathlon-training sessions and activities.

But even so, this is a great tool to utilize for your fitness training which is, by the way, an important-factor to consider as well when you really want to improve in your line of activity.

The features that I have mentioned above are all applicable to running, swimming, and cycling. Plus, it is water-resistant that is applicable up to 100 meters. And this is in some way and somehow what makes this a great additional tool for your triathlon activities.

And these largely include a built-in GPS-tracker (which I must say - it can really provide a strong GPS signal!), heart rate monitor, dedicated application, and step counter. Also, it is water-resistant. Accordingly, it can also support your swimming sessions.

In addition, the data that it can collect from your activities can be transferred easily to the online fitness community of Garmin which is called the Garmin Connect.

Aside from the features that you will get to experience on the Classic 30, the TomTom Classic 100 is also equipped with an automatic interval repetition counter mechanism. Hence, this can support your running, cycling, and swimming sessions.

Accordingly, its value is only fitting for its overall functionality.

Similar to the Suunto Spartan, it has a very simple style and appearance.

However, I am not really satisfied with the way it looks on me when I wear it. But even so, this could still be a great choice for you!

However, keep in mind that this Timex Ironman Sleek 50 is just similar to the Classic 30 and Classic 100 sports watches. The only difference is that the Sleek 50 features a 50-lap memory and an interval training timer.

Also, this one appears to be very vibrant and playful when it comes to its design and style. For some reason, many beginners in the field see this as their top triathlon watch (or at least as one of the best ones).

The Things That You Need to Consider When Choosing a Triathlon Timepiece

If you are looking for the best triathlon watch, then you will need to consider a lot of factors. Apparently, the features alone are too many to mention. And wanting for the best entails a lot of inspections and considerations.

In addition, you will see a lot of variations of these types of watches. From one brand to another and one market to another, you would already come across hundreds of these watches.

Hence, it is only fitting that you learn all the factors that may affect the overall quality of the product and your buying decisions. And just by simply regarding these things, it would already limit your choices!

Keep in mind that these factors are very essential since it could dramatically either make or break your personal preferences.

1. Swimming-Metrics

Swimming is an integral part of triathlon. And considering the swimming metrics alone would already allow you to choose the right triathlon watch for you.

swimming metrics

This is because GPS watches are already established in the market. But, incorporating these watches with the metrics that you would need for your swimming activities and training, it is quite tricky!

Generally, you would want a watch that features an ATM of 5 or more. It is because this feature would mean that it's suitable for your swimming activities. But digging deeper into the metrics, there are two main points that you need to consider:

Swimming Efficiency

Swimming Efficiency is also known as SWOLF. And this feature actually measures the efficiency of your swimming activities. The way it usually works is that it calculates your stroke count, the pool length, and the total time of your activity.

This is very essential if you want to improve your swim speed.

Open Water Mode

If you are competing, this metric is highly essential. And this is because triathlon competitions generally take place in an open water area and not swimming pools. Hence, your watch must have this feature if you are training for a competition.

2. Cycling Metrics

Today, there are quite a lot of sports watches that features a decent cycling mode. And this is because cycling is not a very limited activity. Apparently, even simple homeowners today are engaging in this sports and activity.

cycling metrics

But as a triathlete, you do not only need a decent cycling mode, but you must have a reliable cycling mode in your chosen triathlon watch.

Typically, the features that you must consider for this specific metric are the Cadence and GPS signal capacity. Using these features will help you measure your speed and distance. However, if you really want to invest in improving your cycling capacity, you must look for a power meter unit that you can connect with your chosen pick.

3. Running Metrics

Generally, any fitness tracker or sports watch already provides the basic running metric features that you will need. It is pretty standard actually.

running metrics

But, if you are aiming to obtain the best watch for your training, then you must consider the more serious features for maintaining and improving your running activities.

These features would largely revolve around Cadence, Vertical Oscillation, and Ground Contact Time.

Cadence is simply the steps you make per minute. As for the Vertical Oscillation, it is essentially the range of time that you bounce up and down as you make each of your steps. And the Ground Contact Time is mainly the one that tracks the overall time that your foot spends from hitting the ground all the way to lifting it up.

Typically, any basic watch for active people already features the metrics that you would need for your running and cycling activities.

4. Heart-Rate Sensor and Fitness-Tracker

A decent triathlon watch must have an efficient and effective heart rate monitor. This is because your chosen one will serve as your all-inclusive fitness tracker as well.

And monitoring your heart rate is just one of the basic metrics that you will need in order to increase your accuracy and precision in your triathlon activities.

In terms of being a fitness tracker, your best watch must also have a quality internal accelerometer that is largely responsible for tracking your fitness levels.

5. Waterproofing and Weatherproofing

It is no rocket science at all that your triathlon timepieces, just like tactical watches, must be water-resistant and weather-proof. Aside from the fact that you will do a lot of swimming activities, triathlon is a sport that is largely done outdoors.

Accordingly, you will need a watch that can really go with you, side by side, anytime and anywhere, and whatever the weather condition might be, especially if you are competing!

6. Connectivity and Compatibility

The connectivity and compatibility aspects of a sports timepiece are normally the most overlooked factors by many consumers and buyers. It is very important for you to take note that the best triathlon watches must have the most efficient GPS signal.

The GPS feature in your timepiece is the one that is mainly responsible for tracking your distance, location, and pace. There is actually a reason why a triathlon timepiece is, most of the time, called as a GPS watch.

connectivity and compatibility

Keep in mind that without this feature, the metrics for all of the events of your triathlon activities will be useless and pointless. Hence, you must ensure that the watch you are planning to buy has an efficient built-in GPS tracker.

Also, it is important that this GPS-tracker no longer needs to be connected to a smartphone because that would be really inconvenient, especially during your swim training.

As for the compatibility concerns, most triathletes today have their respective third-party fitness and training applications. And if you do have one, make sure that this application is compatible with the watch that you intend to purchase.

But even so, triathlon watches of today normally come with their own built-in training and fitness software.

7. Recovery Stats

Some sports watches feature a system that can provide your recovery stats. Personally, I find this very useful since knowing these data can largely help me improve my training sessions.

Although this feature is highly optional, I still suggest that you find the best triathlon watches that comes with a feature that can provide you with your real-time recovery stats.

8. Durability

The durability of your chosen timepiece is a very important-factor to consider as well. It is important for you to keep in mind that triathlon is comprised of three events. Certainly, you will need a watch that can keep up with you and your activities.

Also, it is only fitting that you choose a one that is very durable. Essentially, these types of watches are not really cheap. In fact, you will really need to set a budget before you buy a triathlon watch.

And surely, you don’t want to invest your money in a product that can only last for a few months, right? So, I suggest that you check and inspect the durability of the watch along with its features and parts. Most of the time, just by knowing the materials that are used in the construction, you will already have an idea how durable a certain product is.

9. Battery Life

Another important factor that you need to consider is the battery life. As I have mentioned earlier, you will need a GPS watch that can keep up with you and your activities.

Accordingly, you must choose a one that can sustain your training sessions and activities. Remember, triathlon is not a single event. You will surely need time. And the features of your chosen timepiece will be of no use if the watch is already dead.

10. Price and Inclusions

GPS watches, triathlon watches, and sports watches are not really cheap. This is why I always see them as investments. And surely, before making a purchase, you will need to set a budget.

On an average note, a pretty decent one that can provide you with all the features that you will need in your activities would require you to shell out a few hundred bucks. And this would normally range at a price below $500.

Although there are some watches of this type that has a price below $100, they do not usually feature the exact things that would help you in your training.

Accordingly, this is also one of the many reasons why you would need to consider the factors that would affect your buying decisions. And if you really want to have the best triathlon watch of today, you must prepare yoursself to invest.

As for the package inclusions, there are deals in the market today that would offer the watch along with chest strap bands, extra battery packs, repair kits, and other accessories. These inclusions are appealing to some buyers.

Others, however, would want to purchase them separately. But, that would cost more. Hence, I suggest that you choose a package that is all-inclusive already.

The Verdict

All of the watches I included here in this guide are all great and impressive. But, there is only one watch that stands out the most, even over the Garmin Fenix 5. And for me personally, the best one is the Garmin Fenix 3 GPS Watch.

Primarily, it has all the features and metrics that any beginner, intermediate, and professional triathlete would need in their respective training sessions and activities.

And secondly, the battery life of this watch is quite unbeatable. Moreover, it also comes with a power-saving feature that could lengthen further the lifespan of the battery.

Although it is one of the most expensive triathlon watches of today, it is a good watch to invest on. And I would really recommend you to invest in these kinds of watches, especially if you really want to improve your triathlon skills.
