Model: Citizen “Summer's Night” AQ4100-22L

Year: 2025

Limited Edition: 400 Pieces

Features:

The Tech. Eco-Drive is Citizen’s proprietary solar-powered technology, capable of running a watch for up to six months on less than a day of sunlight. They’re so reliable and convenient that I regularly hear people half-jokingly complain about how an Eco-Drive has “taken over” their collection and become their go-to daily wearer. Stylistically, however, Eco-Drives have often been uninspiring. The need for a translucent dial to allow light to reach the solar capacitor has historically limited design possibilities. 

The Dial. That all changed in 2017, Citizen engineers realised that Tosa Washi paper - one of the thinnest yet strongest papers in the world - could serve as a textured, translucent dial material. The paper is used in Japanese walls and doors to bring in light while maintaining privacy, and they're sometimes decorated to give colour to a room, or, in this case, a watch dial. 

The Theme. The AQ4100-22L is a summer’s night, with the hand-dyed indigo dial depicting a gentle river flowing in the moonlight. The gold accented second hand becomes a firefly skipping across the river’s still surface. 

The Precision. Beyond aesthetics, these movements are also accurate. Really accurate. They’re good for ±5 seconds per year, and the battery is rated for decades. After wearing one of these for 20 years, not only will it still be ticking, but it won’t have deviated more than a minute and a half. 

The Case. The eagle emblem on the dial and caseback represents Citizen’s “symbol of confidence and pride”, reserved exclusively for their finest timepieces. The case itself is rafted from Duratect-coated “Super” Titanium, making it remarkably lightweight and five times harder than stainless steel.

The Anniversary. Released as part The Citizen's Nature Collection, only 400 examples of the AQ4100-22L were made.

FAQs

Do you ship globally?

Absolutely - our watches are regularly shipped all over the world. Shipping typically takes:

  • 4-9 business days to reach North America
  • 4-12 business days to reach Europe
  • 4-12 business days to reach Asia and Oceania.

All of our packages are securely shipped, fully insured, and trackable door-to-door.

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.
