Strap fits perfectly on my SBGW289.
Bought a strap to match my Grand Seiko SBGA413 "Spring". Color matching a light pink dial watch was a challenge, liked what I saw with Delugs options and decided to give them a try. Had some initial concerns as to whether it would be worth it or not, as well as the wait time to Texas from Singapore. Not only did the strap arrive very quickly through DHL, you can clearly see that the strap itself is exceptional in person. Very satisfied with the product and the buying experience!
I've been looking for a high quality light colored leather strap for summer for my AT 41mm with a white dial and white hand set (can't remember the reference). This strap is fantastic for that. It is extremely comfortable and was soft out of the box. I've gotten compliments from coworkers on it who aren't even into watches. I will definitely be shopping here again for future straps.
