Description

Up for sale is my Seiko Flightmaster GMT, one of Seiko’s hidden gems.

A rare Japanese-market model from the 1990s, this watch combines Seiko innovation with distinctive styling and everyday usability. Powered by the 5M45 Kinetic movement, it charges through wrist motion and features a true GMT complication with independently adjustable hour hand.

Upgraded with a brand-new lithium-ion capacitor right before listing, replacing the older original-style power cell. This improves power reserve from approximately 10-14 days to around 4-6 months.

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

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
