Seiko 6309-8049 – Vintage 1970s Automatic (Unmodified, Original)
Although we specialise in Seiko mods, this watch is not a mod. This is a genuine, unmodified Seiko 6309-8049 from the 1970s – exactly as it left the factory over 40 years ago.
What makes this piece stand out immediately is its stunning faceted crystal, which catches the light from every angle, paired with a vibrant textured blue dial that is pure vintage Seiko charm. This design is a perfect time capsule of the bold aesthetics Seiko experimented with in the early ’70s.

Collector’s Note
Faceted-crystal Seikos from the early 1970s are becoming increasingly difficult to source in clean, original condition. The play of light across the cut glass, paired with Seiko’s experimental dials of the era, has made them highly collectible among enthusiasts. Many surviving examples are heavily worn or have had their crystals replaced — making an intact original like this a rarer find.
This Seiko is more than just a timepiece – it’s a slice of history. The bold dial pattern, unique faceted crystal, and timeless Japanese craftsmanship make it a standout for collectors and vintage lovers alike.

Frequently Asked questions
Order
Why is there a 4-6 week build time?
Every ModWatches UK timepiece is built to order right here in Leeds, UK. We don’t bulk-buy ready-made watches from overseas or slap our logo on generic stock.
Instead, we carefully source each individual component ourselves -often from specialist suppliers around the world – and hand-assemble every watch in-house. Naturally this can take some time depending on how many orders we have in our queue.
This process takes time, because every piece is crafted with precision, tested on a timographer for accuracy, and undergoes thorough quality control before leaving our workshop.
Before we ever sold a single watch, we built them for our own collections – driven by passion, not profit and sharing our builds on our Youtube channel.
That same care and attention still guide every build today. So while we almost always beat the 4 week mark, it can occasionally take up to 6 weeks to create something genuinely special: a high-quality watch built by enthusiasts, not middlemen.
Do you ship overseas?
Yes
We ship all over the world. Shipping costs will apply and will be added at checkout.
Please note that you will be responsible for any customs payments
How long will it take to get my orders?
Around 5-6 Weeks
Each order is completely bespoke and crafted to your individual preferences by hand. Once your order is placed, we carefully source all the necessary components, inspect each part for quality, and begin the build process.
After assembly, your watch is thoroughly tested using a 24-hour time setter to ensure everything is functioning perfectly.
We then package and ship your watch, with delivery times varying depending on your location and the shipping method selected at checkout.
We know it can feel like a long process -but as they say, anything worth having is worth waiting for, right?
I want to create a custom watch, what changes can I make?
The best way to design your watch is to find an image on the internet which you like and send it to our team on WhatsApp.
We will then be able to advise you on the price and feasibility. Please note that we cannot do custom logos.
I have ordered a watch a few weeks ago, how do I get an update?

General
What is a modded watch?
A modded watch is a timepiece that’s been customised using aftermarket or original parts to create a unique design. Think of it as watch customisation—tailored to your style.
Where do you build your watches?
We build all our watches in Leeds, UK.
Are your watches brand new?
Yes, all the watches we build are made using brand new parts unless clearly stated otherwise. We inspect all components before assembly to ensure the highest quality.
Can you mod my own watch?
At the moment, we only build watches using our own sourced components to maintain quality and consistency.
Are your watches waterproof?
Most of our builds maintain a basic level of water resistance, which is 30m. This is fine up to washing hands and light splashes.
However due to the complex nature of a modified watch we do not reccomend deep submergance or using in the shower.
Do all the dials on the chronograph watches work and function?
Yes, unless stated otherwise, all the dials on our chronographs are fully functional
Is the GMT hand functional on your GMT watches?
Yes, unless stated otherwise, all our GMT watches feature a working GMT hand
Which movements do you use for the watches?
- We use the NH35 movement for most of our watches. This is an automatic movement
- We use the VK63 movement for our chronograph watches (Daytona, etc.). This is a Mecca-quartz movement
- We use the NH34 for our GMT watches. This is an automatic movement
- We use the Miyota 8285 movement for our Day-Date watches. This is an automatic movement
What if something goes wrong with my watch?
- We quality-check and test every watch before dispatch, but if there’s an issue, please reach out within 30 days of delivery. We’ll do our best to make things right.
Do you offer any warranty with the watch?
Yes, we offer a 12 month warrantee starting from the date your watch is shipped. This covers any defects in the movement or overall functionality of the watch.
Please note: As our watches have a basic water resistance rating of 30m, the warranty does not cover water ingress, internal fogging/steaming, or accidental damage.
If you have any questions, feel free to reach out to us via our WhatsApp line — we’re always happy to help.
