Product Details
G-Shock's GM-2100MG-1A is the product of a collaboration with the specialist space programme's popular outreach brand, Space Exploration. Using the acclaimed octagonal GM-2100 ('OB2100') case as the base, the design interprets the lunar surface in two tones: direct sunlight bathing the moon in warm gold contrasted with the absolute black of the far side. The resulting dial and case treatment balances industrial attitude with a surprisingly premium appearance, especially given the octagonal stainless steel insert that gives the bezel its signature premium weight. Shock-resistant construction meets a standard quartz timekeeping module for hassle-free daily accuracy. The black composite resin case and strap are lightweight and comfortable, retaining G-Shock's essential toughness. LED backlight, daily alarm, and stopwatch functions round out the utility package. A strong pick for G-Shock collectors who want something beyond the standard colourways.

Frequently Asked Questions
Do all the G-Shock functions work on this replica?
Yes, the module functions including world time, countdown timer, stopwatch, and alarm are all operational, matching the functional specifications of the GM-2100 module.
What is the case material and how durable is it?
The case uses a resin and metal-bezel construction replicating the GM-2100 hybrid design. It is impact-resistant for everyday wear, though it does not carry the official G-Shock shock rating.
Is the watch water resistant?
It has a basic water resistance suitable for hand washing and light rain. We do not recommend swimming or submersion as the gaskets in replica cases are not rated to the same standard as the original.
