I have this watch for a while now and to be honest its the the best smart watch ive used so far. Especially when in the air. I had the d2 delta as well but this one takes it to the next level. This review covers them but a surprise notice is that the d2 delta could not connect to a gps for full time tracking in the cockpit at high altitudes. However, the mach 1 detected the satellites with extreme accuracy from the A350 cockpit which showed the same ground speed, v/s, xtrk error and much more as the aircraft. Alongside the aviation part, it has all the features of the fenix 7 including sleep tracking etc... I highly recommend this watch to our aviatiors. Youll really enjoy it

Worth mentioning that you must pay a subscription, annually, to get the full use of this watch. All of the non-aviation / non-subscription features of this watch can be found in Garmin products for around the £200 mark, so it's not exactly value for money, and as TFR mentions - would you actually use it as your primary source of NAV . . . ? Unlikely!

i have the d2 delta px if you are in the garmin eco system it's very good load flight plans to it when you take of it automaticaly starts loging you track also loads of other things like heart rate ( very intresting) as a stand alone tool its not practical far to fiddly. good watch for posing though 😎

Feels rather gimmicky!

Nifty, but… The thought crossed my mind, “Its good to have a backup for the iPad, but wouldn’t all the aviation functions be better as a phone app on a bigger screen?” Pulse oximeter, message notifications, etc all are available on less expensive “ordinary” smart watches. Though I’m sure it’s fun if money is no object.

It is a designer watch not a thing that needed. I think I will stick to my smart phone, as the screen is bigger, with most of the same functions available and cost a lot less and can be paired to other much cheaper smart watches if you really what to be notified of social media or hart rate type stuff. But if you have the cash and want to flash it then why not.

I can sure imagine a situation where emergency mode would pay for the watch many times over. Multiple failures in the air, gotta get down NOW.

While I was looking at that little screen I would not be looking out of the windscreen !!

Something else to charge up…!

£1295 for a watch and then you have to spend many hours to learn how to use it, then keep on top of it because if you don't always use it, you'll end up forgetting how it works. It's a lovely looking watch but I don't understand why anybody would want one when you can do most things on your phone, table, or the aircraft's installed panels.

looks a bit gimmicky to me. i've got an onboard GNSS, plus my ipad, plus conventional nav equipment... managing those alone is enough to keep me busy

Anyone else concerned about his bpm at 104 and oxymeter reading 95?

Get a Garmin for fitness tracking. Anything else is a gimmick.

Your channel seems to be on a rapid descent into teleshopping. Commercial relationships could be getting in the way of independent reporting. Product reviews of this and that, innocuous airfield profiles; I have to say your content is not what it used to be.

Utterly useless. Not that’s necessarily a bad thing. Rolexes keep time far worse than any McDonalds happy meal watch would, but they’re not purchased for telling the time. Issue with a smart watch is that in 5 years this will be a laggy, unsupported piece of junk. It’ll be absolutely worthless. Rolexes don’t have that issue.
