Rare bird alert! Here we have the super rare Grand Seiko SBGA105 Spring Drive, one of the undisputed hits of Basel World 2014 and a watch containing simply one of the most mesmerising dials I've ever seen.

The sweep of the second hand due to the 9R15 Spring Drive movement is something you need to see too.

These were released in 2014 and were limited to 500, quickly selling out. They rarely come up on the used market, so don't miss your opportunity to snag one of the coolest Grand Seiko's going around.

Wears quite large for a 40mm, and is substantial on the wrist while also being extremely comfortable. Would make a great daily wearer. See images attached on my 7.5 inch wrist to get an idea of wrist presence.

It's in well used condition, and looks to have been a daily wearer. There's no major dings, but scratching and scuffs on most surfaces. There's a minor pin dent on below the crown and I've added an image though it is small so difficult to see.

Winding is smooth, time keeping is ridiculously accurate, and the power reserve is flawless.

Comes with outer sleeve, outer box, inner box, instructions, signed warranty card (December 2014), all links and a Grand Seiko pin buckle.
