The YASHDUN YSD5071 Quartz Watch (Live Edition) delivers a commanding motorsport presence paired with reliable daily calendar functionality. Housed in an aggressive 41mm * 45mm square alloy case with a 13mm depth profile and a solid 106g build, this timepiece is driven by an authentic precision quartz caliber movement. Beneath the square flat mineral glass lens, the hydraulic finished dial face showcases an intricate, multi-layered automotive engine skeleton illusion architecture with a discrete quick-set calendar window positioned between 4 and 5 o'clock, framed by a rugged gear-edged bezel with structural corner rivet accents. Completed with an ordinary winding crown shielded by heavy side guards, an advanced vacuum furnace ion-plated finish, an integrated 27mm wide high-performance sculpted silicone sport strap, and a heavy-duty black stainless steel D-buckle closure, it offers an assertive and cutting-edge masculine statement.
