TONA MOD | Black Meteorit RoseGold - 40mm

Few dial materials stop a room like meteorite. The Tona Mod Black Meteorit Rosegold pairs a genuine meteorite-pattern dial — with its unmistakable Widmanstätten crystalline structure — against a rose-gold toned case trim and a 40 mm black steel case. The result is a racing chronograph aesthetic that feels simultaneously ancient and razor-modern: a piece of material that fell from space, set in a sports watch built to read a lap time at a glance. MedoMods assembled this entirely by hand, pairing the striking dial with a movement choice that suits how you want to use it.

Movement Options

The Tona Mod is offered in two configurations. The primary version runs the Seiko VK63 mecha-quartz, which drives a fully functional chronograph: start, stop, and reset via the pushers at two and four o'clock. The VK63 blends quartz accuracy with the fluid hand motion of a mechanical gear train — the chronograph seconds hand sweeps, not ticks. An NH35 automatic option is also available for customers who prefer a self-winding movement; in that configuration the pushers and subdial registers are decorative and non-functional, serving the visual composition of the dial rather than a timing purpose.

Case & Crystal

The 40 mm case in 316L stainless steel measures approximately 12 mm thick, wearing slim enough for a shirt cuff. The sapphire crystal is scratch-resistant, protecting the meteorite dial that sits beneath it. Water resistance is rated to 5 ATM — suitable for hand-washing and rain exposure, not for diving. The 316L stainless steel bracelet adjusts from approximately 14.5 cm to 22 cm, and a free bracelet-sizing tool ships with every order so you can dial in the fit at home.

Dial & Design

The meteorite dial's crystalline pattern is unique on every watch — no two meteorite slices share the exact same structure, which means your Tona Mod Black Meteorit Rosegold is genuinely one of a kind at the dial level. Rose-gold toned accents on the hands, indices, and pushers create a warm contrast against the dark case, while the tachymeter bezel rim reinforces the racing chronograph character. The variant choice — with or without logo — lets you decide how much branding appears on the dial.

On the Wrist

At 40 mm this is a versatile size: substantial enough for the sporty-watch crowd, not so large that it overwhelms a dressed-up occasion. The 316L steel bracelet is solid-feeling without being heavy, and the overall package wears with a confidence that comes from knowing the dial material has literally been through space.
