Quality takes time.
The Tona Mod Meteorite Purple combines two things that rarely appear together on a watch at this price: a genuine meteorite-pattern dial and a violet-purple colour treatment that shifts tone under different light. Built by hand at MedoMods, this Seiko Mod chronograph is for the collector who wants a piece that is genuinely hard to find anywhere else — not a recolour of a standard option, but a deliberate statement dial.
The Seiko VK63 Meca-Quartz hybrid movement drives this build. The chronograph hand is actuated mechanically — the pusher engages a real lever system — while quartz regulation supports timekeeping. The result is a chronograph you can use daily. The chronograph seconds hand starts, stops and resets via the pushers.
40 mm stainless steel case – a restrained footprint that lets the dial do the talking without overwhelming a medium-sized wrist
Sapphire crystal with Super-LumiNova indices – high-hardness glass over a dial that deserves protection; lume indices readable in the dark
Screw-down crown & 5 ATM water resistance – everyday splash and rain resistance; the crown seats firmly under pressure
Tachymeter bezel – engraved scale for speed measurement; frames the dial composition and reinforces the sport-chronograph DNA
904L stainless steel bracelet – adjustable 14.5–22 cm, 20 mm lug width; corrosion-resistant high-grade steel that pairs well with the purple dial across steel and dark outfits alike
Meteorite dials carry a natural Widmanstatten crystal pattern formed over billions of years — no two pieces look exactly the same. Adding the purple tone to the surface creates a dial that catches the eye differently at every angle: sometimes gunmetal, sometimes violet, always interesting. This is not a colour for the shy, but paired with the steel bracelet and case it stays grounded. A Seiko Mod chronograph for someone who has seen the usual options and wants something more.
Hand-assembled by MedoMods. Worldwide shipping with tracking – within the EU, no customs fees. Each meteorite dial section is unique — reach out if you want photos of the specific piece in stock before ordering.
Secure payment
A Seiko mod is a modified watch that uses an authentic Seiko movement, combined with third-party high-quality parts. Most of our watches come in stainless steel with sapphire crystal.
It usually takes 10–12 days from order to delivery. The reason: we build every watch by hand only after you order it. It then goes through quality control, and only after that do we ship it. With Priority Build (an optional extra for €9.99, chosen on the product page) your watch moves to the front of the bench.
Absolutely. Send us an email with your order number and full name after ordering, stating your desired design or that you want to remove the logo. You can also leave a note at checkout, or contact us before ordering.
Yes. Every watch comes with a 2-year warranty from delivery. It covers manufacturing defects and functional problems under normal use. It doesn't cover scratches, damage from opening the watch, or water damage. If your watch is rated 5 ATM, hand-washing and rain are fine. Avoid diving, hot water and showering.
MedoMods is run by AM GbR, based in Leimen near Heidelberg, Germany. Our address and VAT ID are in the legal notice. You pay through Stripe, for example by card, PayPal or Klarna, and your card details never reach us. For deliveries to the UK, USA and Australia, we offer 14-day returns from delivery. We do not charge an additional restocking fee. We issue refunds within 4 calendar days after receiving the return. Every watch comes with a 2-year warranty. You can find our seller ratings on eBay.
We push prices down as much as we can. We believe many comparable watches are overpriced because shops bundle extras (like extra straps) into the price. We let you choose what you want, so you only pay for what you actually need.
Yes. We source from suppliers who sell authentic Seiko movements. The specific movement is listed on each model’s product page. If you suspect that your watch contains the wrong movement or a non-genuine one, contact us with your order number and a description.
