The G-SHOCK Ref. 6900 - Subtract by Ed Sheeran is inspired by the album artwork for Sheeran’s latest album, Subtract. The album cover features an abstract rendering of Sheeran’s portrait, loosely resembling the shape of a heart. Subtract is the fourth and final album in a series of mathematics-inspired releases, and it is seen as Sheeran’s most vulnerable and touching album to date, featuring music that Sheeran describes as “honest and true” to where he was in life during the recording. This honest self-expression carries itself through the design of the album’s namesake watch. 

The G-SHOCK Ref. 6900 - Subtract by Ed Sheeran features a resin case and strap dominated by a bold and bright yellow - certainly a daring color, but one that works surprisingly well on the wrist. The strap is adorned with black watercolor splatters that pull inspiration from the album's peripheral artwork and includes a black strap keeper. Solid black is further used across the case, indicating the Mode and Start/Stop indicators and the Adjust and Split/Reset indicators. The same yellow & black colorway was applied to the illuminator button at the base of the dial. 

And this is where things get really interesting. The entire dial is the abstract interpretation of Ed’s face, as well as a sketched subtraction sign at 12 o’clock, as seen on the Subtract album cover. It pulls in muted reds, oranges, greens, and blues, which help to balance the bright yellow of the case. The iconic G-SHOCK “Triple Graph” display features yellow surrounds - a subtle way to pull the colors from the case into the dial.
