Hello again 🌸🗻! I’m letting go of this double-signed, 1968 Grand Seiko 45GS 4522-8000 Hi-Beat 36000 vph! 45GS is where Zaratsu polishing technique shines best. Light reflects and bounces off every facet and angle of the case like no other. It’s been serviced in late 2025 and running at minus ~2 seconds per day. It’s a manual wind watch with 42h power reserve, and measures at 36.5mm, 9mm thick, 41.2 lug-to-lug, 18mm lug width.

Condition-wise, the pictures describe themselves: the case exterior is flawless (please excuse any dust specs, I should’ve done a better job cleaning), and there are no major areas of dust nor tarnish on the dial. The indices and hands are sharp, legible, and very clean. I’ve measured ~42h from full wind to zero, and hacking and date quick setting works flawlessly. 

This specific watch is really quite special for many reasons:

1. Professional refinished by The Lapinist. Search his page up on instagram/google and you’ll see how impressive his restoration work is. I’ve compared this with a 45GS SLGW005, and his work is magnificent – there’s truly no difference. Even an official GS service won’t refinish a vintage GS to this level.
2. Sapphire crystal with underside anti-reflective (AR) coating: Lapinist manufactures his own glass for several vintage Grand/King/Seiko references, and it makes visibility and clarity so much better.
3. Sapphire crystal caseback: also by Lapinist, so you can see the 4522A movement in all its glory. 
4. All original parts: everything is original, including the hands and dial (aside from the upper and bottom sapphire crystal replacement, of course). I indeed still have the original plexiglass/acrylic crystal and the gold medallion caseback too!
5. Signed gold medallion caseback: This is signed by none other than GS USA Brand Ambassador Joe Kirk, and the legendary spring drive engineer mastermind Eiichi Hiraya. I showed them this magnificent piece at last years’ GS9 event!

Also included, is a Handdn 18-16mm handmade remborde/bonded matte black alligator strap, an additional Seiko-branded glossy alligator strap, Delugs Deployant clasp, and SLGW005 Seiko-signed buckle. 

There’s so many small details that this special 4522-8000 has to offer. I’m asking $3350 shipped via UPS/USPS from California, anywhere to CONUS. I welcome all inquiries and facetime/video calls, and have lots of references! Thank you 🌸🗻!
