Help me choose between GW-M5610U and GW-B5000

Hi

I am happy owner of Casio Lineage LCW-M100TSE-1AJF.
In the past weeks, I have started to looking closer and closer to gshocks for a small sturdy/beater watch.
I want compact and light watch with positive display (and without colored tints), solar power, that can be synced (in anyway).
I have narrowed down my choice to two models GW-M5610U-1 and GW-B5000MG GW-B5600MG (or any other that will come with positive display)
The GW-5000U also fits the bill but at $280 is too expensive.

Pros of the GW-M5610U-1
  • It's more compact (Height: 46.7 vs 48.9 mm. Depth: 12.7 mm vs 13.4 mm)
  • It's around $100

Pros of the GW-B5000MG GW-B5600MG
  • It has Bluetooth (which I am not sure I need, but it's nice to have)
  • Maybe a better display?
On ebay it sells for $200 which is above MSRP. Maybe it's supply issue due to covid. I would be willing to pay $150 for this.

The GW-B56000MG uses a separate foil solar panel whereas the GW-M5610U has the solar panel integrated in the glass.
It is not clear to me is how much more legible the display of the GW-B5600MG if at all.

In my view, the 5610 is an essential square. It's got the core set of desirable features, gives you pretty much everything you want in a square at a great price. Out of all my squares, this is the one I reach for when I want the core G-Shock experience. And it's very readable, self-setting, and is incredibly comfortable. Even more so if you swap in the 5000 rubbery strap.

My experience is that for G-Shocks that have a minimalist function set, I prefer MB6 because BT provides no additional value in setting or using. However, for G-Shocks that have multiple, complex, or memory-based functions (like Mudmaster GG-B100) I prefer using the iOS app and BT because it's easier to program and recall.

If I were to own one square out of all squares, the optimal point would be the GWM-5610U.

I understand your feelings and I am also kind like the idea of being untethered to the phone. However, as engineer I see big problems with MB6. Aside from the fact that it might be shutdown at some point, the main issue is that MB6 is not a secure protocol. Specifically there are is no authentication. Anybody with the right equipment can create a fake emitter and you wouldn't be able to tell if the signal is coming from WWVB or an impostor. The pro is that you can hack an emitter and the watch will pick it up (there are mobile apps on the phone that can do that with a low power output).
The flip side is if some bad actor wants to create a big mess, they could just set up a high power antenna next to major city and turn it on at 11:59pm broadcasting the wrong time. All the radio controlled devices would be wrong the next day.

BT is fairly popular standard, nobody knows how long it will be around and nobody knows how long Casio will support their mobile app, however BT is secure (or at least more secure). This is an additional value of BT over MB6.

Granted. But this stuff in the second quote is smack dab in the middle of tinfoil hat territory.

In my opinion, as an engineer, there can be a huge valley between the technically feasible in principle and that which is likely to occur given plausible motivating factors. If we didn't recognize that, there's no way anyone could live a life substantially free from unfounded anxiety and paranoia.

But hey, you do you. In the mean time, I'm enjoying my MB6, BT, and "dumb" G-Shocks.

The GW-B5600MG-1C has a slight green tint but it doesn't affect legibility. Is less pronounced than the gold tone on the GW-B5600BC-1. Both have good contrast and viewing angles. And yes, the GW-M5610U-1C has a slight blue tint as well.

If you travel you might appreciate having Bluetooth as well for time and date calibration. A lot of the world doesn’t have MB6 coverage.

The GW-B5600MG is out of production now after just a short production run which might explain the higher pricing. I snapped one up for the same reason I think many others did: at last there was a positive display BT square without garish colours. It’s a shame it was discontinued.

The aesthetics are quite different between the two, with the MG being a lot cleaner and minimalistic. It has a subtle camo pattern around the display which only presents under certain light.

The MG doesn’t have the battery indicator on screen (in my experience my watches stay pretty much fully charged during normal use anyway).

If you’re concerned about device security, some security conscious workplace settings such as the military don’t allow Bluetooth capable watches.

I got confirmation of this. I am sure Gshock will crack out another GW-B5600 with positive display at some point.


adg31: Thanks for the photos. It is reassuring to see that clarity is about the same.

I am happy I opened an account on the forum. I got some great comparison shots. Maybe I'll end like you guys owning multiple gshocks.

I find that aesthetically I tend to prefer the face of the GW-M5610U with its classic red band and acres of text.
It’s also slightly thinner than the GW-5600MG - but only very slightly so in terms of comfort there’s very little in it.
In terms of clarity of display I really can’t see any difference between them!
I’d say the GW-5600MG is handy if you travel extensively as you can use the BT connectivity to synch with your mobile rather than trying to figure out the nearest city in the time zone you are travelling to.
Then again I like the ‘self-contained’ nature of the GW-M5610U that doesn’t require linkage to an external device to see things like the battery level.
All now give you the facility to show the home time in the date box which is again useful when you’re travelling.
Staying with the date box all of them now give you the option to configure DD/MM or MM/DD. This is something which had previously put me off the GW-M5610 model with its fixed MM/DD display.
I like that the light can be programmed for 2-4 seconds on the GW-5600MG rather than 1-3 seconds on the GW-M5610U as I find getting older my eyes take longer to read the time in the dark!
The lack of an on-screen battery indicator isn’t something that really bothers me but falls into the category of ‘nice-to-have’.
Is there an outright winner?
When it comes to jobs like gardening, pressure washing the car or patio or DIY I tend to reach for the GW-M5610U as it is the cheapest and easiest to replace if I did manage to kill it (unlikely) so I suppose that would make it the winner if the question was which is the classic G-Shock.
However, for me, the winner would be the GW-5000U as it has the original solid steel core and ‘heritage’ but is it worth the extra?
Only you can answer that one - so good luck and wear it in good health!

Either would be a great choice! I think the risk of someone hacking the atomic signal is pretty low... it would take quite a bit of effort for likely little impact (if they set it to be more than ten minutes off, everyone would notice the second they picked up their phone or looked at any non-atomic clock... and the overall number of people who rely on atomic time is low compared with the general population).

With Bluetooth is also possible your phone could be hacked... historically, I'm guessing more individual phones have been hacked than atomic time signals emulated.

(@ adg31 and @ D. A. (Tony) Vader )

Ok, so I put my hands on a 5610U. It fits me well (I think).

The issue I see that there is a clear reflection when I look at it straight on. I was wondering if this is happening with GW-B5600 (and the other models with separate solar foil)?

Sorry for bothering everyone!!

(you can see the phone reflection here)

Yes, I think you'll notice some reflection on most g-shocks with mineral glass. Slightly less on watches with Sapphire crystal + AR coating. Personally, ir doesn't bother me, though.
