Grand Seiko SBGP011

Offered for sale is my Grand Seiko SBGP011, part of the Grand Seiko Heritage Collection. This piece is only being sold to fund another purchase.

This model is equipped with the world renowned Calibre 9F85 movement (accurate to +- 10 seconds per year!), which includes an independent hour hand adjustment function—allowing you to change time zones or daylight savings time without hacking the seconds hand and losing accuracy.

The original purchase date was 24/10/2025, and I purchased the watch from Segundor in The Netherlands on 19/06/2026. It is covered by the remainder of the Grand Seiko 2 year International Warranty as well as Segundor’s 12 month warranty.

The watch is in excellent condition overall, which lines up with the gentle use it has had. I have tried to capture any tiny marks on the case, but it’s hard even with 2x zoom and holding the phone close. None of those slight marks are viewable during normal wear.
The crystal is unmarked.
As can be seen from the pictures, the black dial and 20mm lug width mean the watch suits a myriad of straps and can be dressed up or down.

Comes as a full set with box, papers and spare links.

Happy to answer any questions.

Thanks for looking.
