The Story

The Casio MTD-Series: Classic diver style made accessible

The Casio MTD-Series is a reminder that a great diver-style watch doesn’t have to be complicated. With their bold rotating bezels, highly readable dials, and versatile styling across the 125, 135, and 140 models, this series focuses on the features that matter most in an everyday sports watch.

At the heart of the design is the unmistakable diver aesthetic. The MTD-125 pairs a classic anti-reverse rotating timer bezel with a highly practical day and date display. The MTD-135 shifts its date window neatly to the 4 o’clock position to maintain a streamlined, professional-diver look. Meanwhile, the MTD-140 offers a clean marine-sports profile with a classic 3-hand date display, ensuring every model provides a balanced layout that is both functional and easy on the eye.

The sturdy cases deliver a timeless, sporty look that works equally well in the office or on the weekend. Combined with reliable quartz movements and substantial water resistance—an impressive 100 metres for the MTD-125 and MTD-140, and 50 metres for the MTD-135—these watches capture the adventurous spirit of diving while being built for years of dependable, low-maintenance use.

Our stock includes these three distinct variants, each offering its own take on the same proven formula. Whether you prefer the day-date practicality of the 125, the classic diver confidence of the 135, or the clean sporty profile of the 140, every version shares the qualities that make the MTD-Series such a popular choice: practicality, reliability and enduring style.

CASIO MTD-125D-2A2VDF

The Coastal Turquoise

Turquoise dial that sits somewhere between sea-green and sky-blue, framed by a sporty rotating bezel. A colour you don’t see often at this level — fresh, distinctive, and surprisingly easy to pair with almost anything.

CASIO MTD-125D-1A3VDF

The Night Diver

Black dial with luminescent hands and contrasting accents against a stainless steel frame. Dark, legible, and built around clarity. The kind of watch that works just as well under office light as it does under open water.

The Golden Signal

The Golden Signal

Yellow dial with bold Arabic numerals and a sporty rotating bezel. Unapologetically vibrant — it catches the eye from across the room. For the wearer who wants presence without pretension, and a marine edge to match.

CASIO MTD-135D-1AVDF

The Black Current

Black dial behind an aluminum diver-style bezel, with a date window tucked neatly at four o’clock. Clean, purposeful, and quietly confident. Diver aesthetics without the weight of a full dive watch.

CASIO MTD-135D-2AVDF

The Open Water

Blue dial with silver-tone markers and a colour-matched aluminum bezel. Reads deeper indoors, lighter in the sun — always moving between tones. A classic marine palette that earns its place on the wrist.

CASIO MTD-135D-3AVDF

The Green Depth

Green dial matched to a green aluminum bezel, with luminous hands that cut through low light. Rich and saturated without being loud. An increasingly popular colour choice that feels modern and grounded at the same time.

CASIO MTD-135D-7AVDF

The White Helm

White dial with silver markers and a clean diver-style bezel. Bright, open, and easy to read at a glance. Brings a lighter attitude to the sporty silhouette — a refreshing alternative to the usual dark-dial territory.

The Evergreen

Green dial set against a black resin strap and steel case. Earthy and functional, with a colour that sits comfortably between adventure gear and everyday wear. Light, unfussy, and ready for whatever comes next.

CASIO MTD-140D-3AVDF

The Evergreen Steel

Intense green dial in a full stainless steel build, at 138g on the wrist. Bold, modern, and increasingly hard to ignore as green cements itself as a go-to dial colour. Feels considered rather than trendy.

CASIO MTD-140D-1AVDF

The Dark Anchor

Black sunburst dial with a full stainless steel bracelet and silver-tone bezel. The sunburst finish shifts subtly under different lighting — flat black in the shade, alive with texture in the sun. A solid all-rounder that anchors any rotation.

CASIO MTD-140-2AVDF

The Deep Drift

Deep blue dial paired with a black resin strap and grey stainless steel bezel. A marine-inspired combination that leans casual and rugged. Lightweight on the wrist at 75g, built for days that go from dry land to open water.

CASIO MTD-140D-2AVDF

The Deep Steel

Blue dial housed in a full stainless steel package — case, bezel, and bracelet. A step up in weight and wrist presence from its resin-strap sibling. The kind of blue that can dress up or down, depending on the day.
