The timekeeping is quartz — accurate to within seconds per month, no drift, no regulation required. The chronograph is mechanical — the snap-back reset is a physical mechanism that returns the hand to zero in a single decisive press. Press stop. Press reset. The hand snaps to zero instantly. No electronic delay. No waiting. The most satisfying chronograph reset available at any price. Sapphire Crystal — Why It Matters Every ZJani watch uses genuine sapphire crystal as standard. Rated Mohs 9 — the same hardness as a ruby. It does not scratch from keys, desk surfaces, belt buckles, gym equipment, or any material you encounter in daily wear. After a year of daily wear the crystal looks identical to day one. Mineral glass scratches from all of these contacts within weeks. At this price — sapphire crystal is non-negotiable and it is what you are getting. Yellow Silicon Strap — Built for Active Wear The yellow silicon strap matches the dial — creating a cohesive, bold aesthetic from dial to wrist. Silicon is sweat-resistant, water-resistant, and dries immediately after any water exposure. Comfortable through gym sessions, runs, and all-day active wear. Does not degrade in heat, humidity, or repeated water exposure. The correct strap for a bold active chronograph. How to Use the Chronograph Start: Press the top pusher — the central hand begins sweeping. Stop: Press the top pusher again — the hand stops. Reset: Press the bottom pusher — the hand snaps back to zero instantly. Use it to time gym intervals, cooking, meetings, lap times — anything that requires precise elapsed time without checking a phone.
