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, 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 chronograph seconds hand starts, stops and resets via the pushers. The chronograph starts, stops, and resets with crisp mechanical pushers, giving you that satisfying tactile feedback without battery-draining complications. No winding required.
