There are 2 versions of the 5610:
GW-M5610 (first pic)
GW-M5610U (second pic)

The U version uses a LED backlight and has in my eyes more contrast.

 

 

No problems with my 5610.

 

I would stay away from the negative displays unless you find something that really appeals to you.

 

From what I've read, the GW-B5600MG-1 is one of the best solar G-Shocks for display contrast. I believe the solar panel on the GW-B5600 series is not mounted on a glass sheet as it is with most solar G-Shocks (like the GW-M5610 series), so internal reflections are reduced, which increases the display contrast. Also, these models have an LED backlight rather than EL, which also increases the display contrast. The MG colorway is one of the few GW-B5600 models with an untinted, positive display. Unfortunately, this model seems to be discontinued.

Indeed:

 

It's not an issue on any watch. It's a problem.

 

The question is open enough for me to say any analog solar gshock can easily beat most digital solar gshocks. Having said that most of my watches are full digital. I have only a few analog.

 

Not every analog, not easily for sure....

 

MIPS one... then STN one and then rest

 

Blame your eyesight, not the watch

 

STN displays are, of course, very good:

 

G-Shock analog dials and hands tend to be a hot mess. The best legible digital display is STN but it doesn't seem as bright as the old standard display. EL backlit actually makes the clarity worse so the new LED implementation maybe the way to go imo.

If not a G-Shock then obviously a traditional 3 hander with internal AR on the crystal is your best bet. Sapphire at least according to Seiko does not have the best acuity (their Hardlex performs better), traditional acrylic crystal like on the base model Speedy Pro actually gives a warm tone.

Also when outdoors under the sun, the glass lenses like on an old B&L Ray-Ban with a traditional 6 base curve will always be clearer with least distortions than let's say polycarbonate lenses on an Oakley wraparound or those hipster superflat lenses with some ridiculous base curve like 2 and worse yet reverse lenses (trying to prime the consumer with future display electronics)? Lmao!
