Model: 7400-c70007, Citizen Radio Control

Year Produced: 1993

Features: 

The Origin. Released in 1993, Citizen’s 7400 was the world’s first radio-controlled analogue watch. Not only was it a technical milestone, it looked beautifully strange doing it. During the design phase, Citizen encountered a serious problem - the metal parts of the movement would sometimes block the radio signal. The solution? Elevate the antenna above the movement and all of its signal blocking parts. 

The Functionality. The result is striking. It might look like the antenna sits above the crystal, but it’s actually buried inside it, giving the watch its distinct look. But it’s not just an unusual face - there’s a 12/24-hour subdial, as well as a time zone selector that gives the watch GMT functionality, and a push-activated calendar. 

The How. Once per day (at different times depending on the day of the week), the watch will check for Atomic Clock Radio Waves. If you’re within 800km of an appropriate tower the watch can automatically adjust the time to be correct to the second. By pressing a combination of buttons, you can also make the watch manually confirm the time using radio waves whenever convenient. Thanks to modern technology, you can use your phone to spoof radio signals if you don’t live close enough to a radio transmitter.

Do I have to pay customs or taxes?

It depends on so many factors, including but not limited to; the cost of the watch, the type of watch you've bought (vintage, new, or modified), and the import and tax laws of your country. If you're unsure we recommend checking the import laws that relate to your country before ordering.

Are your watches water resistant?

All of our watch mods are tested by our own pressure depth testing equipment, and are guaranteed to resistant water up to 50m of depth. Seiko Originals have varied levels of depth resistance, which will be stated in the description of each watch.

Can I modify an existing design?

We welcome all ideas! Get in touch via the Contact Us page and we can let you know the possibility and cost of any potential alterations.

What is your returns policy?

Due to the hand-made nature of the Seiko Mods, we offer a 7 day returns period after the watch has been received. The returner must bear the cost of the returns, and the watch must be returned in the same condition as it arrived. We do not offer returns on any bespoke or custom-made watches.

Due to the vintage nature of the Seiko Originals, returns are considered on a case-by-case basis, as vintage items typically have a no returns policy.
