Combining the rugged aesthetics of a classic professional diver watch with modern office versatility, this model is built for the dynamic lifestyle of contemporary gentlemen. Brought to you in Sri Lanka by Ranasinghe Watch Works, this timepiece delivers dependable Japanese engineering, premium steel finishing, and functional day-to-day features. Whether navigating corporate boardrooms in Colombo or enjoying weekend coastal getaways, the Casio MTD-135D-1AVDF delivers timeless wrist presence.

Premium Design

Constructed with meticulous attention to detail, the Casio MTD-135D-1AVDF features a multi-finish metallic presence. The dual combination of brushed and polished stainless steel gives the watch a substantial, luxurious feel. Its outer diver-style bezel accented in aluminum creates a sport-chic profile that matches tailored suits, casual weekend attire, and active sportswear seamlessly.

Dial Features

The focal point of the MTD-135D-1AVDF is its high-contrast, deep black dial. Designed for quick legibility under any light, it features clear hour markers and silver-toned skeletal hands treated with luminescent accents. A practical date window is conveniently positioned at the 4 o’clock mark, preserving symmetry while delivering quick visual information.

Case Features

Engineered to protect internal mechanics, the case measures 50 mm in length, 43.6 mm in width, and a surprisingly slim 9.3 mm in depth. This balanced architecture provides a confident, masculine presence without adding bulk under shirt cuffs. Protecting the dial is a tough mineral glass crystal that guards against accidental scratches, scuffs, and daily wear.

Movement

At the heart of this timepiece is a high-precision Japanese Quartz movement. Renowned worldwide for unyielding reliability, the quartz movement maintains exceptional accuracy within ±20 seconds per month. Powered by an SR920SW battery, it offers approximately 3 years of worry-free operation before requiring a simple battery swap.

Strap/Bracelet

The watch comes fitted with a heavy-duty stainless steel bracelet designed for resilience and style. Equipped with a One-touch 3-fold clasp, it fastens securely while making putting on or taking off the watch effortless. The lug-to-clasp sizing accommodates wrist circumferences from 150 mm to 205 mm effortlessly.

Water Resistance

With a 50-meter (5 bar / 5 ATM) water resistance rating, the Casio MTD-135D-1AVDF is built to keep up with daily water exposure. It easily handles rain bursts, handwashing, accidental splashes, and short surface swimming, giving you complete peace of mind.

Comfort

Despite its robust steel build, the watch weighs approximately 126 grams, distributing weight evenly around your wrist. The sleek 9.3 mm slim profile ensures it rests comfortably against your skin for continuous all-day wear.

Ideal For

This versatile wristwatch is tailored for:

• Professionals seeking an everyday corporate watch with dynamic style.
