Description
All-blue, all-steel: the Tona Mod Blue Rubber Blue Steel is the purist version of the racing chronograph Seiko mod. Where the rose-gold variant warms the palette, this build keeps everything cool and monochromatic — blue dial, blue rubber strap, steel case and subdial accents — and the result is a watch that looks effortlessly considered. The 40 mm 316L stainless steel case wears the tachymeter bezel and three-subdial layout with exactly the right level of sporting seriousness.
Movement
The Seiko VK63 Meca-Quartz movement drives a fully functional chronograph; start, stop, and reset work as intended.
Case & Crystal
The 40 mm case is 316L stainless steel throughout, with a case thickness of approximately 12 mm — substantial but not oppressive on the wrist. Sapphire crystal keeps the dial scratch-free and clear in any light. Water resistance is 5 ATM: fine for daily wear and casual water exposure. The bracelet adjusts from approximately 14.5 cm to 22 cm using the included sizing tool.
Dial & Design
The all-blue steel combination gives this Tona variant a motorsport-inspired coherence. There is no colour clash to manage, no warm-cool tension to negotiate — just a unified blue palette across dial, strap, and steel accents. The subdial architecture is clearly laid out, with the pushers at 2 and 4 o'clock giving the case that unmistakably chronograph profile. With Logo or No Logo: your call.
On the Wrist
The blue rubber strap keeps this build comfortable across temperature ranges — it does not stiffen in cold or become slippery in heat the way some straps do. At 40 mm the Tona is sized for wrists that want a presence without bulk. The unified blue palette means this watch pairs surprisingly well with both casual and smart casual dress.

FAQ
What is a Seiko mod?
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.
How long will it take to receive my watch?
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.
Can I customize the logo or remove it?
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.
Do you offer a warranty?
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.
Is MedoMods a legitimate shop?
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.
Why are your watches cheaper than those in other shops?
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.
Do you use genuine Seiko movements?
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.
Are the watches hand-built?
Yes — all our watches are built by hand.
