One Direction's debut perfume, "Our Moment," may break history, and is expected to make the One Direction boys a fortune within the first week of sales.

"Our Moment" launched at Harrods on August 25 and is set to earn the singers $561,312 (or 360,000 pounds) in its first week on sale in the U.K., according to The Daily Mail, E! News reports. The figure was calculated from pre-order sales plus the more than 3,000 bottles that have been sold in just two days at the Harrods in London.

"Our Moment is predicted to sell around 180,000 units in the first week alone, making it one of the fastest-selling fragrances of all time," Escentual.com CEO Rakesh Aggarwal said, E! News reports.

"It's certainly looking like it's going to be the most successful celebrity perfume launch of the year and sales in America are expected to be bigger still."

Specifically, 180,000 sales of the most popular 30ml Eau de Parfum, which retails at £19.99, will bring the turnover for the first week to come in at nearly £3.6m, The Daily Mail reports. Though the exact deal struck by the One Direction boys is a "closely guarded secret," industry insiders have estimated that Harry Styles, Zayn Malik, Niall Horan, Liam Payne and Louis Tomlinson will personally earn around £2 for every 30ml Eau de Parfum bottle sold, which means the group is due to bank £360,000 in 7 days, The Daily Mail writes.

Spokesperson for The Fragrance Shop, who will start selling the fragrance on Monday, said, "We launched the pre-order for Our Moment on August 1 and since then have taken over 20,000 pre-orders from across Europe."

Vogue U.K. reported that, surprisingly, twenty percent of the consumers are males, E! News notes. The age gap for One Direction's perfume is also quite large, with everyone on the waiting list ranging from 16 to 68.

One Direction's "Our Moment" perfume is a mix of grapefruit, berries and red currants, according to E! News.
