Triathlon Watch Buying Guide

How We Chose Our Selection Of Triathlon Watches

The products we’ve listed in our comprehensive review were narrowed down from an extensive range of available Triathlon watches and devices. We haven’t just picked out the ten most expensive, cheapest or stylish. Instead, we’ve weighed up a whole range of criteria in order to make our final recommendations.

Brand - While brand isn’t everything, it certainly is important, especially when it comes to tech. Buying from a reputable and trusted brand with a good history and pedigree should mean that you are buying with confidence from a company who really understands about wearable tech. That’s why you will find a wide range of brands in our guides, including many names you will instantly know and recognize.

Reviews - What is it that they say? The customer is always right! No matter how amazing a product sounds on paper, the proof is in the performance, and you can’t beat customer feedback for lifting the lid on what the genuine experience of using a product in the field is. That’s why we always refer to extensive customer feedback and reviews to get a gauge for how our product recommendations tested in the real-life hands of other customers.

Price - While the price point may well be an important consideration for many of you, value of money and buying quality is something we prefer to focus on. Products should be priced appropriately versus their features and dependability. That’s why we include a broad cross-section of final price points to appeal to a range of customer budgets.

Features To Look For In Triathlon Watches

With so much choice and availability when it comes to the popular category of Triathlon watches, picking out your own personal favorite could be a challenge. You need a watch that’s rugged and durable enough to withstand exposure to water, dirt as well as sweat but which is also sensible and accurate enough to pick up those all-important timings and intervals. Tri watches can also feature additional physiological information relating to heart rate, calories expended, and not just steps traversed and laps completed. Below we’ve listed out some of the key features we recommend you consider.

Durability - Even the most careful triathlete is likely to have an accident at some point or other, either slipping and falling over getting out of the water or transitioning from the bike back onto foot! So it makes sense to go for a watch that is dependable, durable, and which can withstand the rigors of punishing environments and scenarios. Going for something that’s also Shock Proof might also be a sensible idea.

a runner wearing triathlon watch

Water resistance - Given that one of the legs of a Triathlon involves being submerged in water, clearly, water resistance is a pre-requisite! A triathlon watch is about as much use as a chocolate fireguard if you can’t take it into the water with you! However, there is a difference between waterproof to an acceptable ATM and just water resistant. It won’t necessarily be a given either that your chosen watch will track all the sophisticated swimming stats you need it to, including the number of strokes and type of stroke. So decide how detailed you need your underwater metrics to be and what depths you’re likely to be wearing your watch to swim or even dive in.

Battery life - You’re not going to get very far without a decent battery life, and there’s nothing more infuriating than your watch dying halfway around a circuit. So it’s an excellent idea to ensure you invest in a tri watch which has a suitably reliable battery life. That’s even more important if you intend competing as keeping on track of those vital stats will motivate you to push yourself that little bit harder.

Connectivity - Decide whether it’s important to be able to connect and sync your triathlon watch with any other fitness or tracking accessories and apps. Some of the more advanced watches have everything you require already built in while others you might need to separately sync to an external heart rate monitor, cadence, or speed sensor. Bluetooth connectivity is popular and allows the wearer to share and upload info to another smart device such as a tablet or phone.

Display - It makes complete sense to go for a clear, readable display that you can easily view at a glance. You don’t want the readability of the screen to be affected by glare or by dimly lit conditions given that you will be wearing it both in the water, potentially at night and out running and cycling in the mid-afternoon sun. Go for something that has clean, clear, bright, and bold numbers and pictures, but that isn’t too cluttered or distracting either.

Ease Of Use - The last thing you want when you’ve invested in a new Triathlon watch is to struggle with setting it up in the first place. While advanced functionality and enhanced features are all well and good, you need your watch to be user-friendly and functional. It should be your loyal companion and a timepiece you can rely upon to provide you with up to date and accurate statistics. Don’t over complicate things by going for a watch that you just can’t get to grips with. Go for something that is intuitive to operate and that you won’t spend your entire training session fiddling with!
