The compact metal G-Shock case interests me more than the stars
G-Shock: 64/120 bezel clicks. GM-S2110NS Night Sky — black / gray

I like the metal bezel and the relatively slim case, but the stars on this dial are more decoration than I want. The Night Sky idea is clear as soon as I look at it. I just keep imagining the same watch with a quieter face, and that is probably a sign that I prefer another version of the 2100.
There are black- and gray-strap versions, GM-S2110NS-1A and GM-S2110NS-8A. The gray one has the darker bezel treatment and looks a little moodier in the official pictures. The lighter steel bezel on the black version makes the case shape easier to see. I would choose that one between the two, although neither is an immediate want for me.
Small stars on a compact G-Shock
Casio uses a combination of pressing, radial finishing and printing to put raised-looking star patterns across the dial. The metallic hour markers have a half-matte finish. It gives the surface a lot of small changes in texture, especially around the central hands. I can see why someone would enjoy looking at it under changing light; I think it makes the face a little too restless.
The listed case dimensions are 45.9mm long, 40.5mm wide and 11mm thick, with a weight of 56g. The construction combines resin with a stainless-steel bezel, and the supplied strap uses bio-based resin. This isn't a full-metal watch simply because the most visible upper part is steel.
The practical specifications include 200m water resistance, shock resistance, mineral glass and about three years of battery life. There are analog hands and a digital display, world time, stopwatch, countdown timer, five alarms and dual LED lighting. Solar power and Bluetooth time correction are not listed for these exact references. I wouldn't borrow those features from a different 2100 model.
The proportions interest me more than the theme
An 11mm thickness is appealing for a G-Shock with a metal bezel. I would want to try the case on because it could be a comfortable way to get this general look without a very large watch. I haven't handled it, checked the display angles or tested how easily the hands can be read against the stars.
The Japanese official listings give a November 2026 release and a ¥29,150 tax-inclusive retail price for each. That is Japanese pricing, with a confirmed USD price and US order date still unverified as of November 3. I am leaving the dollar chart field unknown.
I give the family 64 out of 120 bezel clicks. The size and steel bezel are things I like. The dial treatment is the part I would have to accept every time I looked down, and I would rather choose a plainer face in this shape.
