Casio MTD-1079D 'black sub' style -- oversized 44 mm dial, luminous dive indices, LED backlight, stainless steel bracelet, mineral crystal.
Casio's MTD-1079D earns its 'black sub' nickname with a dark rotating-style bezel, bold 44 mm dial, and a clean diver-inspired layout that looks far more expensive than its price suggests. The large case size keeps everything legible -- hour markers and hands are generously lumed so night reading is effortless, and the LED backlight fills in any gaps in low ambient light. The stainless steel bracelet is a business-ready complement to what is otherwise a sport-oriented case, giving the MTD-1079D the flexibility to move from active use to office wear without looking out of place. The mineral glass crystal handles everyday wear and the 14.8 mm case thickness gives the piece substantial presence on the wrist without becoming clunky.
The bezel rotates uni-directionally with audible clicks -- fully functional for elapsed time tracking, just like a proper dive bezel should.
44 mm is classic dive watch sizing -- large enough to read underwater (conceptually) and substantial on the wrist without being overwhelming.
We recommend treating it as daily splash resistant rather than for active water sports, to be on the safe side with the rep-grade gaskets.
