Model: Citizen La Mer “Cosmosign” 4390-432100

Year: October 1997

Features:

The History. The Citizen La Mer - French for “The Sea” - was one of the founding models in the brand’s Club La Mer line: an elegant sub-brand created exclusively for the Japanese domestic market. You’ll no doubt recognise the dial as an early prototype of the Campanola Cosmosign, and you’d be right. La Mer Cosmosign watches were among the early inspirations behind the modern Campanola collection.

The Accuracy. Released in 1986, this was the world’s first scientifically accurate star chart wristwatch. Citizen was so proud of its precision that it originally included a loupe to help owners examine every celestial detail. But why is a cosmic watch called The Sea? To pay tribute to ancient Japanese sailors that were guided by the stars, of course!

The Complication. The planisphere chart rotates in real time, displaying the current position of the stars above. It also shows daily sunrise and sunset times - a charmingly analogue way to stay connected to the sky.

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.
