Full Metal 2100 Chronograph Watch GMC-B2100D-1AER

The Watch

Casio is a Japanese brand celebrated for its durable and charming timepieces. Built to stand the test of time, deliver effortless timekeeping, and ensure everyday comfort, they'll quickly become essentials you never want to take off. From the Full Metal 2100 Chronograph series, meet the watch bearing reference GMC-B2100D-1AER. Designed for men's wrists, it features an octagonal case in grey, refined through a high-density assembly crafted from stainless steel and highlighted by both polished and brushed finishes. Fitted with curved lugs, the case measures 46.30 mm in diameter, 51.30 mm in length, 12.40 mm in thickness, and weighs 171 g. Commanding in presence, it features a bezel marked with various functions as well as the "G-Shock" and "Protection" inscriptions, and is protected by a mineral crystal. To its right sits a screwed octagonal crown, flanked on either side of the case by 4 pushers for adjusting the central displays. Water resistance reaches 20 ATM, secured by a screw-locked caseback.

The Dial

This watch features a sophisticated, meticulously crafted dial that delivers precise timekeeping at a glance. Set against a black background with a Super Illuminator backlight, it showcases a sunray finish and a minute track around the rehaut, flanked by baton indices. Coated with a Neobrite treatment - as are the hands sweeping across them - they take on a grey tone for enhanced hour reading precision. For added functionality, between 4 and 5 o'clock you'll find a black aperture displaying the date, a sub-dial showing AM/PM, and three additional sub-dials. Positioned at 6, 9, and 12 o'clock, they display respectively the chronograph function and a second time zone when not activated, retrograde days and battery level, and the watch's current mode. Finally, Casio adds its signature at 3 o'clock.

The Bracelet

This Casio watch comes with a bracelet crafted in stainless steel. Its combination of polished and brushed finishes gives it a refined, elegant look. Interchangeable and featuring a silver tone that pairs effortlessly with any outfit, this bracelet is accented with screws at its ends for added visual interest and is fitted with a deployment clasp to keep it securely on your wrist.

Water Resistance

This model offers water resistance of 20 atmospheres, or 200 meters. This watch is ready to follow you into the deep - it's built for freediving! With its fearless attitude toward water, you can even use high-pressure washers with this timepiece on your wrist without worry. Showering, bathing, lap swimming, and freediving are all fair game. However, for scuba diving with tanks, we recommend a timepiece with a higher water resistance rating. Also, avoid operating the crown or pushers while submerged to preserve the integrity of the mechanism.
