Our Take

The SBGA407, known as the “Skyflake,” captures the quiet beauty of winter in Shinshu with its snow-textured blue dial, inspired by the season’s sky and snowfall. Inside, the in-house Spring Drive caliber 9R65 blends mechanical power with quartz precision, offering ±1 second per day accuracy and a smooth, gliding seconds hand.

This SBGA407 is in good pre-owned condition, showing light to moderate signs of wear consistent with regular use. You'll notice some hairline marks on the case and a bit of light bezel rash around the twelve o’clock position. Aside from that, the watch remains in excellent shape with no major dings, dents, or nicks.

Upon request, we can have the watch professionally refinished to bring it back to like-new condition.

Included are the original box, manual, hangtag, papers dated 2021, and the original sales receipt from the authorized dealer. The watch remains under warranty.
