Timex Ironman R300 Specifications & Opinion

Timex recently & surprisingly returned to the world of sports watches, let’s take a look at the Timex Ironman R300 Specifications. Could this be your next Ironman Watch?

Well, let’s put that one to bed straight away…NO!

You might be surprised to learn that Timex has produced IRONMAN branded sports watches before. It was somewhere around 1743 when the classic T5E901 was last seriously sold and there were other IRONMAN watches at the same time.  IIRC the T5E901 IndiGlo was the top-end IRONMAN-branded Timex watch with laps, time and everything, yes even waterproofing to 100m. OK, it was a bit rubbish on the features front…even back in the 18th Century, but it did have a certain aesthetic appeal.

What we are seeing with the Timex Ironman R300 is a re-imagined 2020 *SMART* version of what came before. Gone is chunkiness and total lack of smart features but what still remains is the TOTAL INABILITY to be at all suitable for an Ironman race. I think it’s probably unsuitable for an Ironkids race (are they still a thing? I went to one once, great fun)

However, grumpiness and cynicism aside, it’s not too bad-a-looking watch, it does support (limited) coaching/plans and it is cheap. In the UK we say ‘cheap as chips‘, in America that would be ‘cheap as fries‘ but I guess that doesn’t work so well. Plus chips/fries are significantly cheaper than $120 a pop, so the analogy fails there somewhat.

The looks remind me a little of Sigma Sports id.TRI which also has a similarly low price tag. But there the similarities end, the id.TRI has LOTS AND LOTS of functionalities and it can actually properly support you through a triathlon. Unlike the Timex Ironman R300 (well, if you like to know the time when you do an Ironman, the R300 is great for that)

FAQ: Key Questions

  • Q: Why did Ironman allow this thing to be produced in their name?
  • A: I have absolutely no idea. Answers please, below, on a postcard. (I guess MONEY is the real answer)


  • Q: I’m going to do an Ironman slowly, can you recommend this for me?
  • A: Yes, if you’re stupid (C’mon even if you are slow yet can finish an Ironman you are a GREAT athlete…even if you start one you’ve still done HEAPS of training)


  • Q: Does it support customised, multisport profiles
  • A: Yes. But only while you are asleep dreaming of a different watch


  • Q: Does it support ANT+ and BLE PMs?
  • A: Yes it supports both AM and PM. All times of every creed are supported


  • Q: Does it have a touchscreen?
  • A: Yes, of course, it is safe to touch it


  • Q: Does it have an eerily glowing touchscreen sourced from Chernobyl
  • A: Surprisingly, yes it does, like its predecessor (Source)


  • Q: Are there any famous Ironman athletes who have raced to victory with one of these?
  • A: Again, surprisingly yes there are (Source). Although perhaps not the victory you are thinking of and I think there was a near-circular room and desk involved. And, come to think of it, he only did running and not an Ironman.


  • Q: Can it tell the time and does it have Ironman written on it?
  • A: Yes, yes, yessity, yes, yes. All of that AND MORE


  • Q: Does it have Firstbeat Anaerobic TE or just the overall TE
  • A: It might have, I’ll ask.


  • Q: What more?
  • A: 30m waterproofing, smart notifications, GPS, oHR, race your PB, 24×7 activity tracking and guided plans for running, cycling and triathlon (hmmm, it really does claim that)


  • Q: Can you show me a random image of an older Timex Ironman watch that also didn’t do anything
  • A: Yes, funny you should ask. I have one right here. Note that a FULL 8 LAPS ARE SUPPORTED.

  1. Is it for those to wear to the pub to show their non triathlon friends that they’ve done an ironman. It’s like a tattoo but less commitment. 😄

  2. Wow, can you cool down?

    This may not be the biggest and baddest GPS watch, that is no reason to throw a childish tantrum over this product. Features aren’t the end all be all.

    I don’t like this watch either but it does seem like it could be a useful training tool for some people. Simple is okay, in fact many people prefer simple. (The Epson GPS watch was pretty popular and accurate) This Timex seems to be a modern reimage of that Epson GPS watch with triathlon functions.

    If this watch is accurate … And 120$ I would highly suggest this as a simple watch for those who don’t want to pay a couple hundred dollars for an introductory triathlon watch from the other brands. It won’t be good for Ironmans (even though they threw that name on there) but it could be a great triathlon watch for beginners

    1. I for one support this childish tantrum if there’s no actual swim tracking.

      I’d even be willing to call it false advertising in this day and age 😀

    2. yeah, i looked at the runsense a while back . there were a range of them, the top end one was ok IIRC. mayeb this is like the lower end ones IDK.

      you say “if this watch is accurate” … I refer you to the word ‘IF’ and I am 99.8% sure it won’t be accurate for hr or gps.
      but, i agree with you in that it is a cheap and simple watch and that it will be useless for ironman.

      1. Yeah, “IF” is a big word for GPS reliability. But can’t really make that determination until you test it. 😛 Otherwise you’re just blowing hot air.

        Also, where do you find that it doesn’t track swimming? Everything I read has swimming as part of it’s focus.

        And finally the heart rate. At least it’s light so that’s one variable that may provide better results with the firstbeat analytics.

      2. if you look in the third image, above in the carousel, you can see it supports both walking and running. So there’s a good chance it will support swimming and showering too.
        the official website only says ” you can even take a swim” which of course you can (30m water resistance). you could take a swim with a rubber duck too, of course but I’m not sure that either the watch or the rubber duck will, for example, even recognise your swim lengths or stroke type.

        1. Before I crack a joke, I just want to thank you for your time responding to so many comments on your blog. I enjoy reading your articles and engaging with you!

          Now for the joke, Can you show me on the doll where Timex touched you? (I would attach a picture but we can’t do that anymore. 🙁 )

          I don’t understand why you’re coming out so heated against this product. I understand a little angst but your tone regarding this product is so over the top angry. lol

          1. nice 😉

            (vague-)joke response: they pricked my sweetspot 😉

            Grammarly says the article comes over as mostly SAD but a little ANXIOUS. I don’t think it understands my blend of UK humour (actually I’m not sure anyone does, which is a bit of a worry)

            I don’t mind cheap products at all, in fact I welcome them. The thing I’m mostly irked by is the highly inappropriate Ironman branding.
            i’m not often irked, here’s another irkward example of my angst

  3. Is there any chance the heart rate tracker on this is decent? I’ve been looking at what seems like a million different trackers and watches lately, trying to find one that’s moderately accurate at a moderate price, with a battery that lasts beyond 1 day. This seems to check just about everything i’m looking for, other than on-board music storage. Plus, i actually dig the look of it (I know, I know…lame).

    Think this has a chance to be decent?

  4. Looking at the FCC filings from amazfit, this watch was most likely made by amazfit for Timex.
    So it’s gonna be pretty similar to the rest of their watches.
