Type

Jewelry (Wristwatch Accessory)

Maker

Casio, organized in Tokyo, Japan (est. 1946). The G-Shock brand was launched in 1983 by Kikuo Ibe and is world-renowned for setting the standard in shock-resistant timepieces.

Material

Stainless steel outer bezel and case with resin inner bumper and resin strap. This is not solid silver; it is industrial brushed and polished stainless steel designed for durability and corrosion resistance.

Dimensions

Standard G-Steel dimensions: approx. 59.1mm length x 52.4mm width x 16.1mm thickness. Weight is approximately 108 grams, which is significant compared to standard resin models.

Description

This Casio G-Shock G-Steel GST-S110 is a robust and masculine timepiece that blends the legendary toughness of the original G-Shock with the professional aesthetics of a steel watch. The multi-dimensional dial features analog hands over three digital LCD sub-dials, providing a depth of field that is both highly legible and visually complex. Its stainless steel bezel provides a protective shroud over the inner resin core, ensuring the watch can survive a 10-meter drop while looking suitable for a business-casual environment.

Key Features

Tough Solar charging system, Layer Guard Structure for dual-material impact absorption, and 'Shock Resist' certification. Distinctive for its oversized industrial screws on the bezel.

Material & Composition

Stainless steel outer bezel and case with resin inner bumper and resin strap. This is not solid silver; it is industrial brushed and polished stainless steel designed for durability and corrosion resistance.

Finish & Decoration

Combination of brushed (satin) and polished stainless steel surfaces. The bezel features industrial-style exposed screws and a multi-layered dial with 3D hour markers and neobrite luminous hands.

Hallmarks & Stamps

Engraved 'CASIO', 'G-SHOCK', and 'SHOCK RESIST' on the bezel. The case back (not visible) typically includes the module number (5445), model number (GST-S110), 'Tough Solar' branding, and the stainless steel mark.

Construction Details

Machine-manufactured with a 'Layer Guard Structure' where stainless steel is layered over shock-absorbing resin. Features a mineral glass lens and a carbon-threaded screw-back or 4-screw plate case construction.

Functional Features

Tough Solar power (charges via light), 20-bar water resistance (200m), double LED light, world time (48 cities), 1/100-second stopwatch, countdown timer, and 5 daily alarms.

Handle & Grip Details

Standard black resin strap with a stainless steel tang buckle. The strap is integrated into the case with heavy-duty metal lugs and pins to maintain structural integrity under impact.

Craftsmanship Details

High-precision automated assembly. The brushwork on the steel lugs is consistent and the transitions between polished and matte surfaces are sharp, indicating quality mass-production standards.

Authentication Indicators

Alignment of the sub-dials is consistent with the Casio 5445 module. Font weight and spacing of 'G-SHOCK' on the bezel are correct. Fakes often have poor LCD contrast and misaligned hour markers.

Origin & Manufacturing

Designed in Japan by Casio. Manufacturing typically occurs in Casio's high-automation facilities in Thailand or China, following strict ISO standards for shock resistance.

Era & Period

Contemporary Digital/Analog Era (21st Century). It reflects the 'rugged luxury' design trend where utilitarian tactical gear is upgraded with high-end metallic materials.

Age Estimate

Circa 2015-2022. The visible 'Tough Solar' and 'WR 20BAR' indicators on the dial are consistent with mid-to-late 2010s production cycles for the G-Steel line.

Cultural Significance

G-Shock has transitioned from a niche tool for construction workers and military personnel to a global fashion icon, frequently seen in streetwear culture and worn by professional divers and pilots.

Condition Notes

Good Pre-owned Condition. Visible scratching on the stainless steel bezel near the 'G-SHOCK' and 'SHOCK RESIST' lettering. Light surface dust on the resin strap. The glass appears clear without major chips.

Value Estimate

$150 - $250 USD depending on the market. Used examples in this condition typically trade between $100 and $160 on secondary markets like eBay or Chrono24.

Care & Maintenance

Wash with mild soap and lukewarm water to remove sweat and salt. Avoid exposing the resin strap to harsh chemicals or sunscreen, which can cause 'resin rot' or brittleness over time.

Similar Pieces

G-Shock MT-G (higher end, made in Japan), Casio Edifice (more formal, lower shock resistance), or Seiko Prospex 'Arnie' (competitor solar diver).

Interesting Facts

The G-Shock brand was born from a 'Project Team Tough' which tested over 200 prototypes by throwing them out of third-story windows before the first model was finalized.
