TONA MOD - METEORITE

The Tona Mod Meteorite is a handcrafted Seiko Mod chronograph built around a genuine meteorite-pattern dial — each piece carries a texture formed over billions of years, making it one of the most distinctive dials you can wear on your wrist. Assembled by hand at MedoMods in Germany, this is a sport chronograph designed for people who want something that looks like nothing else in the room.

Movement & Timing

At the heart of the Tona Mod sits the Seiko VK63 meca-quartz hybrid movement. Unlike a purely electronic chronograph, the VK63 drives the chronograph hands mechanically — you feel a real sweep when you push the pusher, not a digital jump. Accuracy stays within quartz tolerances, so you never have to worry about drift across a long timing session. The seconds hand sweeps continuously, giving the watch the visual character of a mechanical without the service complexity.

Case & Crystal

• 40 mm stainless steel case – compact enough to wear under a cuff, present enough to carry a dial like this

• Sapphire crystal with Super-LumiNova indices – scratch-resistant glass, readable in low light

• Screw-down crown & 5 ATM water resistance – built for everyday confidence, rain or splash included

• Tachymeter bezel – classic racing scale for speed or rate calculations

Bracelet

• 904L stainless steel bracelet – the same steel grade used in high-end Swiss production, adjustable from 14.5 to 22 cm with 20 mm lug width

Why the Meteorite Dial

Meteorite dials are cut from real Gibeon iron meteorite, which means the Widmanstatten pattern — that unmistakable crystalline cross-hatch — is unique to every single piece. No two are identical. Paired with a chronograph sub-dial layout and a tachymeter ring, the result is a watch that bridges deep-space material with a sport-watch silhouette. If you want a conversation-starting Seiko Mod that is as technically interesting as it looks, this is the one.
