Our take on the Casio G-Shock Full Metal Analog Digital Smartphone Link Grey Dial Tough Solar GM-B2100SD-1A 200M Men's Watch

The GM-B2100SD is the full-metal version of the G-Shock 2100 series, the octagonal "CasiOak" case shape. It combines analog hands with a small digital display, Bluetooth smartphone link for automatic time sync and phone finding, and Tough Solar charging from any light source. The stainless steel case and bracelet give it a dressier look than the resin 2100 models, at the cost of more weight and a higher price. It suits people who want a rugged 200M watch that reads well with a jacket, and it competes with steel sports watches rather than plastic G-Shocks.

Questions and answers

How is this different from the resin G-Shock 2100?
This is the full-metal version: stainless steel case and bracelet instead of resin, with the same octagonal shape and 200M rating. It is heavier and feels more like a steel sports watch.
Do I need the phone app to use it?
No. The watch runs on its own with solar power and analog hands. The Bluetooth link adds automatic time sync, phone finding and settings changes from the app.
How does Tough Solar work here?
A solar cell under the dial charges from daylight and most indoor light. It keeps the watch running without routine battery replacement, though deep storage in the dark drains it.
Is it safe for swimming?
Yes. It is rated to 200 meters, so swimming and snorkeling are fine. Avoid pressing the buttons underwater and skip saturation diving.
What is in the box?
The watch on its steel bracelet, a presentation box and paperwork. Check the listing for the exact included items before ordering.
Will it fit a large wrist?
The bracelet has removable links for adjustment, and the case is on the larger side. Try it on or check the case diameter if you have a small wrist.
Where is the Casio G-Shock Full Metal Analog Digital Smartphone Link Grey Dial Tough Solar GM-B2100SD-1A 200M Men's Watch cheapest?
