Casio G-Shock G-Steel analog stainless steel watch black 44 mm GMC-2500D-1AER
Casio G-Shock GMC-2500D-1AER brings the octagonal heritage of the 1983 DW-5000C into the contemporary fully analog 2500 series. Its purposeful case, clear analog layout and practical timing functions create a distinctive CasioNaut character for everyday wear.
The GMC-2500D-1AER pairs a black brass dial with a silver-tone stainless-steel bezel and a silver stainless-steel bracelet. It gives the 2500-series CasioNaut a more substantial metallic presence, while the one-touch three-fold clasp makes the bracelet practical to secure. CasioNaut is an unofficial enthusiast nickname, not an official Casio name; the design is inspired by the DW-5000C and has no Patek Philippe affiliation. The case is not all steel: its construction includes resin and bio-based resin, with the stainless steel concentrated in the bezel and bracelet.
The two-eye layout keeps the hour and minute hands easy to read while the small seconds register sits at 9 o'clock. At 3 o'clock, the three-cell Multi-Mission Date window shows the date, stopwatch elapsed minutes and useful setting or function information.
Once the year, month and date have been set, the full auto-calendar remains correct through 2099. This dependable analog convenience means you can read the date at a glance without giving up the traditional character of an analog watch.
The special analog movement was developed for this series and manufactured at Yamagata Casio. Its magnetic Shock Release Hand attaches the minute hand securely while absorbing and distributing the force of impacts, helping preserve reliable hand positioning.
A new CR1025 battery provides approximately 2 years of operation with Second Hand Sleep disabled, or approximately 5 years when Second Hand Sleep is enabled. In sleep mode, the small seconds hand stops to conserve energy; the five-year figure is conditional, not unconditional.
This is a genuine G-Shock built for shock resistance and 200 m / 20 bar water resistance. Mineral glass, Neobrite and an amber LED with afterglow add practical legibility, day or night, without compromising the watch's robust character.

Shock resistant
A so called shock resistant construction protects the watch against shocks and vibrations.
LED light
A light diode (light-emitting diode / LED) is used to light up the dial of the watch.
Neo-display
A luminous coating requires xposure to light, to provide a light effect in the dark.
Date display
The date is shown on the display.
Stopwatch 1 second - 30 minutes capacity
Running time, interval time and the final time are measured within the nearest second, and it can measure time up to 30 minutes.
Auto calendar
Corrects automatically for months/years with different lengths.
Long batterylife
The battery in this watch will last at least 2 years, because the watch use less energy.
Stainless steel bracelet
Tough, durable and elegant; a bracelet made of stainless steel gives the watch a classic quality look.
Mineral crystal
This, very durable, mineral crystal has improved protection.
Quartz Watch
A battery-powered quartz watch is controlled by fluctuations in a crystal of the mineral quartz. These oscillations change very little over time, which is why quartz is often used - because it retains its accuracy.
Water protection: 200 meter (20 bar)
This watch can be worn while swimming/snorkeling (near the surface). The value refers to the pressure in water, at that depth, while motionless... and should not be seen as the depth for wearing the watch..
Condensation - important!
Rapid changes in temperature can cause condensation inside the watch. If you notice moisture beneath the glass, you should immediately go to a watchmaker, who can open and dry the watch. Even if the signs of moisture disappears, by themselves... the moisture will not - and will eventually damage your watch - so, visit a professional and remove it permanently. Even waterproof watches are not protected against condensation, so keep that in mind if you plan to go from very hot to very cold temperatures - like from a hot sauna directly to the snow. If condensation occurs, it very rarely (if ever) depends on manufacturing, so if your watch is damaged by moisture, warranty will probably not cover it (it could be manufacturing issues, but... most likely it will be because of the rapid change of temperature = natural causes).
Case made of stainless steel.
Sizes
Does this watch fit your wrist? Wristwatches has gradually become larger in size, and a typical men's watch is usually between 40 and 45 mm wide. If you have a wrist that is noticeable larger/smaller, we recommend that you focus on the sizes in/outside the outer edges of the typical sizes. You are always welcome to contact our support, so we can share our experience with you.

How is the size of the watch measured?
The diameter
The common term is diameter, but since not all watches have circular watch cases, the diameter is actually the width measured from left to right. Note that some manufacturers include the crown (to set the clock) and the buttons when measuring the width, but we try to standardize all the watches by not including the crown as part of the measured width.
The thickness - or height of the watch in profile - is indicated by measuring the watch from top to bottom as illustrated below. By comparison, a 1-euro coin is 2.33 millimeters thick.
One usually defines the watches with these numbers:
Slim: 4-6 millimeter
Normal: 6-12 millimeter
Big: 12-14 millimeter
Oversize: 14-18 millimeter
