Features:

The Theme. A reminder to make every second count. The “EKG”, named after the electrocardiogram heartbeat reading that’s acting as its second hand. The average human heart beats up to three billion times before eventually giving up, and this custom watch has been designed to make you consider the importance of every beat. To further drive this point home, and represent its fragility, the dial that houses the 18k gold heart is paper-textured.

The Heart. It’s undeniable satisfying to watch the heart “beat”. Thanks to the skeletonised NH71 Seiko movement, the exhibition caseback, and the very literal open heart dial design, you can see all the watch through the watch from the front. 

The Chapter Ring. Black and gold, hand-painted, with Kanji hour markers (1-12).

The Hands. Dauphine hour and minute hands paired with a custom-designed EKG heartbeat second hand.

The Case. Nautilus-style with a mix of brushed and mirror-polished surfaces, screw-down crown, and 50m water resistance

The Crystal. Flat sapphire crystal with a clear anti-reflective coating on the underside.

The Strap. Matte-black leather with a golden buckle.

The Movement. Regulated Seiko NH71 skeletonised movement, accurate to +/- 5 seconds per day with a 42-hour power reserve

FAQs

Are your watches authentic?

Everything we sell is 100% authentic.

All of our watches are inspected and verified for authenticity - both inside and out. We have over 15 years of sourcing and collecting rare watches in Japan, which is often considered to be one of the best markets for authentic and fully original vintage watches.

Do you ship globally?

We are based in Japan and regularly ship all over the world. We typically use FedEx and it takes:

  • 3-7 business days to reach North America
  • 3-7 business days to reach Europe
  • 3-7 business days to reach Asia and Oceania.

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

Are all of your watches serviced?

Most but not all of our watches are serviced. The "Condition" section of each watch will confirm if the watch has been serviced.

All of our watches are tested by an independent watchmaker - if a service is needed, the watch will be serviced. If a service hasn't been conducted, it's because the watch itself is too new to need a service, or there is evidence of a recent service.

What payment methods do you accept?

We accept payment by all major Credit Cards and Wise.com

What condition are your watches?

Due to the vintage and neo-vintage nature of the watches we typically sell, the condition varies from watch to watch. However, our photos are high resolution and our descriptions are accurate. You can buy with confidence knowing there won't be any nasty surprises.

If the condition of a watch is ever misrepresented, we would offer a full refund.

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 or new), and the import 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?

Our serviced watches are typically tested to their original water resistant specifications, but we would never recommend pushing vintage or neo-vintage watches to their depth limits.

What is your returns policy?

Due to the vintage and neo-vintage nature of most of our watches, we do not offer returns under normal circumstances. All sales should be considered final.
