The shows will take place at 2pm and 4pm, and there will be DJ sets from midday until the store's closure.
The G-Shock Session is taking place as part of Crepe City, Europe’s largest festival devoted to sneakers, which will descend on The Old Truman Brewery on the same day.
G-Shock will have a presence at the event, and will showcase its various collaborations – which have included the Wu-Tang Clan's black and yellow model through to a watch designed by the Royal Air Force.
The brand is aiming to drive those attending Crepe City to its nearby store, where there will be discounted products available throughout the day.
A number of other brands are expected to feature at Crepe City, however exact details are yet to be revealed.
Tim Gould, head of marketing at Casio UK, said: "This partnership with Crepe City is spot on for G-SHOCK, we’re proud of our heritage in street culture and the sneaker community has always been one of our most passionate supporters.
"We’re excited to welcome Ghetts back to the G-Shock East store for this event, he’s a dynamic and authentic talent, and as a Sessions alumni, it’s been fantastic to watch him grow as an artist. We know he’ll make this an unmissable G-Shock Sessions event."
Ron Raichura and Morgan Weekes, co-founders of Crepe City, added: "For sneaker heads, matching your outfit to your sneakers is just part of everyday life and your watch is part of this.
"G-Shock’s classic range has so many models and variations of colourways, and the brand has been a real authority in street style ever since the early 90s, so we are really pleased to be working with them."
G-Shock Sessions are designed to showcase up-and-coming artists from the UK's undergound music scene, and have been going since 2010.
Last year the watch brand toured a branded bus around local skate parks in five UK cities.
