Is a G with a steel case and screw down case back more water/ shock resistant than a regular G with a resin case and a case back with 4 screws?

Watches with steel case would last longer, at least you don't need to worry about broken lugs.

Other than the obvious fact that steel is a more durable materiel than plastic /resin.
Is there any other advantages to a steel case( shock resistance wise) and a screw down case back (water resistance wise)?
I would assume it is a little bit more water resistant because the same case back is used on most dive watches.
I also wonder if the same gaskets / seals are used in resin and steel cases.
I read here somewhere that the GW-5000 is more water resistant than a regular resin squares, but not sure why, the most logical thing is that the screw down case back is responsible for that.
Regarding the steel being more Shock resistant, i have no idea.

In my experience, the main difference is the reduced risk of damaging the threads on the case when changing battery and bezels. I have a 1996 resin cased G-Shock where one of the holes for the bezel has a damaged thread, luckily it's not on of the holes that hold down the back plate or it might compromise water resistant.

As far as water resistance they both say 200M on them. I guess it's possible one could have an advantage but it probably doesn't matter for your uses.
I assume they go through the same shock tests and both meet their minimum standards. The screwback is better rgd cracked lugs and/or damaged springbar holes, etc.

I personally prefer a steel case.
Only because I like the 'heft' of a steel case, and I (rightly or wrongly) associate a steel case, with quality.
I don't worry about water resistance because I don't swim in my watches.
Saying that though, I'd prefer a 300m water resistance case to a 50m water resistance case.
Why?!, I hear you cry, 'you have just stated you don't swim in you're watches'?! :roll:
Well, again, I associate a higher water resistance, (again rightly or wrongly), with a higher standard of construction and better constructional materials used to gain that higher water resistance. :-!

Just get the gw5000 already watchw... or any steel cased square...

then buy a $40 dw-5600e for those days that you wanna go swimming (or showering) :) if by any chance (and i mean a 0.0000000000001% chance) that water gets in and kill the dw5600e, youre only out $40.

total spend:

gw-5000 $300
dw-5600e $40
————————-
=====> $340 (or less if you can source a cheaper gw-5000)

Well as we know all Gs have 200m WR. But I suspect that steel-cased Gs would be able to go far deeper than that without any problem, probably farther than the resin-cased models. There are youtube videos where the GWF-1000 Frog was taken much deeper than 200m, and survived. A steel case will resist deep water pressure better than resin, I'm sure. That said, you won't need that.

I'd guess that resin cases have better shock resistance, but that's only a guess, I'm not an engineer. But I've seen a video where the GW-5000 took a lot of abuse without any trouble, so no worries either way I'd say.

Now, please let us know what your specific concerns are re. water resistance and shock resistance... How are you going to use the watch where you might be concerned about both of those things? Why are you asking this question?

For this to be an issue, there would have to be a difference in distortion of the watch case under that given pressure and I doubt there will be any such difference.

Other than (possibly) differences in shape between screw-back gasket and flat-back gasket, I doubt there would be much if any difference in the gaskets employed at the buttons either.

Indeed I doubt gaskets for 100m and 200m, but even for 50m watches are different. A good example is the water resistance specs difference between PRW3500 series and PRW3000 series.

There is no reason for me to ask other than pure curiosity, I'm sure they both will survive a shower (;
Just thought that It's interesting and there isn't enough info on how steel G's are different than resin G's, obviously they are the same for everyday use, but I'm sure there are differences beyond that.

lol ok...
I guess that steel just feels better than resin,the weight, the touch of it(especially if it's DLC coated...) and it's more durable ,but nothing more beyond that...
I would still always prefer a steel case, it just feels more like a "real " watch, the Rangeman i had was just too light! it was weird because it was pretty big.
There's also the psychological side of it... you're just less affraid it will break, or melt or something because steel just feels stronger...:)
