Seiko Astron SBXC075 (Limited edition with box & papers)

A rare opportunity to acquire the Seiko Astron SBXC075 Honda e Limited Edition, a highly exclusive model that merges Seiko’s most advanced GPS Solar technology with the design philosophy of Honda’s groundbreaking electric vehicle.

Limited to just 300 pieces globally, this reference stands out as one of the most design-driven and collectible modern Astron releases.

Many watch and automotive collaborations tend to follow a predictable formula - add a logo to the dial, change a colour, and call it “limited.” This is not one of those.
The SBXC075 was designed from the ground up in partnership with Honda, specifically to celebrate the launch of the Honda E electric vehicle. Rather than superficial branding, the watch reflects a shared design philosophy and engineering mindset between the two brands.
The result is a piece where the collaboration is felt in every detail.

For those who want to explore the full design story and official details, Seiko created a dedicated webpage specifically for this model:

The page is in Japanese, so using your browser’s built-in translator is recommended.
It provides excellent insight into the design philosophy, collaboration background, and unique features of this reference.

***********************************************

Hi there! I’m a long-time watch enthusiast and collector with over 20 years of experience in the hobby. I’m mainly into Japanese watches: Grand Seiko, high-end Seiko, Casio Oceanus - basically anything that offers great value and proper watchmaking without the silly price tags. I like watches that punch above their weight, and that’s exactly the type I tend to buy, wear, and sell.

Every watch I sell is carefully inspected and photographed by me. I take pride in showing the watch honestly - no hidden marks, no stock photos, no surprises. What you see in the pictures is exactly what you’ll receive.

I’m based in Lixnaw, Co. Kerry and have built a solid track record here on Adverts.ie for being straightforward, reliable, and easy to deal with. I don’t entertain lowballing, as my prices are already fair. Lowballers and other 'exotic offer' experts, please ignore this sale.
And just to be fully clear: I’m not looking for swaps or part exchanges. I prefer straight cash sales only.

All my watches are graded using my standardised condition scale:

N (New) — unworn condition. Typically includes full set (box, papers, tags).

S (Like New) — almost indistinguishable from new. No visible scratches or marks. Crystal and case flawless.

A (Excellent) — Lightly worn with minimal signs of use. Minor hairline scratches visible only on close inspection.

V (Very good) — Gently used with only minor signs of use; the crystal may carry minor traces consistent with normal wear, but they do not stand out. Overall condition remains clean and attractive.

B (Good) — Regularly worn with moderate signs of use. Noticeable scratches on case or bracelet; crystal may have faint marks but remains in good condition.

C (Fair) — Clearly worn with pronounced scratches, dings, or crystal marks. Functional but cosmetic wear is obvious; may benefit from servicing.

Cheers!
Jake
