Does anyone know if the upcoming Marq 3 athlete or adventurer series will have an LED flashlight?

There is no such thing as a MARQ Gen3...

I actually hope they dont. Id preffer the "luxury" style of the watch and its clean lines with silicone bands aligned to the watch. 

I think the flashlight being absent is a bad reason to not invest in the product. I have the tactix 7 pro and have used to flash light once in the two years i've owned it, just to show it off. The light is simply not strong enough to be realistically useful. A small flashlight should always be a part of your EDC anyways. That being said the price point of the MARQ gen 2 is extremely high considering it doesn't offer too much more than the fenix and tactix models. Smart watches do not last forever and if you spend close to 3000 usd on a piece of tech, you want it to last at least 20 years before upgrading.

I don’t have an issue to spend 3K on a mark, as long as it build quality and finish are top notch and incorporate the features of a  luxury watch ( domed Safire glass, full titanium body, ceramic bezel, etc….) with attention to detail. Idd guess it’s for those that (still) feel a watch is also a piece of juwelery, something you simple lik to look at or feel complements you as a person.

The fact that is has a shorter lifespan then for e.g. a high end luxury watch does not bother me. That said my brother has a 10 year old Garmin watch and it’s still working perfect.

They could relocate the barometer and place it between the two buttons on the right side. I honestly think that would be a better location with the light pointing forward, but that would require a setting to rotate the display 180 degrees (like Apple Watch) for people wearing it on the right hand.

It doesn't sound like you're a Marq owner.  We pay for the superior materials and aesthetics. And to be fair to Garmin, they've never sold them as having more features. If you don't like the look or it's not your thing, Garmin offers plenty of other models with, as you say, the same or even more functionality. 

BTW there is a still flashlight functionality on the Marq, just using the display rather than a dedicated LED. Even on its minimum setting (with a red light), I've found it good enough for situations where I've been stuck in pitch black. I use it quite often. 

My brother owns the MARQ Captain Gen 2, the materials used in the collection like titanium and carbon fiber, cost around $50 to $100 USD per kilogram. Even if you double that and take the higher end of $200 per kg, you'd still only be looking at about $20 for the case materials per watch. Add another 30 dollars for the titanium strap and $100 for manufacturing and labor (which is mostly automated), and I’d expect the total cost to be around $150 to $200 USD (around $250 CAD), which is an overestimate. Titanium and carbon fiber aren’t expensive enough to justify such a steep price increase.

I bought my Tactix 7 Pro for $1,575 CAD when it launched, while the MARQ Gen 2 Captain is priced at $3,200 CAD. Considering the difference in materials, the addition of the irregular heartbeat monitor, and the better display, I’d expect a price bump of around $700 CAD.  But the gross increase of $1,500 CAD for minimal upgrades feels more like something Apple would do.

If they included a two-year outdoor map subscription in the price, which is valued at $60 USD per year, it might be more justifiable since it's a premium collection, something more to stand out between standard users. Or even if they added LTE the price would be understandable. But what they tried to do was make it a luxury watch when it is a smart watch and loses value significantly when the next gen comes around(as seen on eBay)

My brother likes his MARQ, but agrees as well that it is way too overpriced for what it offers. Several Garmin power users on YouTube agree with this too in their reviews of it, and say they wouldn't purchase it.

I didn't get it for its functions.  My Epix does as much.  I got it because its as premium of a smartwatch as I can get as close to the swiss watches I  (although less these days) wear.
