TONA MOD - SKY STRIKER

The Tona Mod Sky Striker is a chronograph Seiko Mod built for those who want precise timing and a bold aviation-inspired aesthetic on the wrist. At 40 mm the case sits confidently without overpowering — a format that works equally well with a flight jacket or a crisp shirt. The Sky Striker sits within MedoMods' Tona lineup: sport-chronograph mods assembled by hand in Germany, drawing on decades of motorsport and pilot-watch design language. The tachymeter bezel and chronograph pushers are functional from day one, not decorative afterthoughts.

Movement & Accuracy

Inside runs the Seiko VK63 meca-quartz hybrid. The seconds hand sweeps with a smooth continuous motion — indistinguishable from a mechanical chronograph at a glance — while the quartz oscillator keeps the time accurate to within a few seconds per month. The chronograph starts, stops, and resets with crisp mechanical pushers, giving you that satisfying tactile feedback without battery-draining complications. No winding, no rate adjustment required.
