Flaunting the watches on Instagram, the unbeaten former world boxing champion said he takes a watch for every day of the week when on holiday, including his $18m Jacob & Co 'Billionaire' piece.
A collection of its watches will be available for viewing at the store on Park Avenue in a few months.
The line is the company's first contactless range and follows its partnership with Barclaycard.
Three watches have been released as part of the move, all made from carbon.
Released in June of this year, the dahlia C1 was designed with the aim to combine traditional watchmaking and jewellery into one piece.
The new collection combines polished plasma high-tech ceramic on the case with diamonds displayed as a ring on the dial.
The collection is available for both men and women as a range of chronographs.
The collection is split into two categories, aiming to hone in on both the business and casual sectors.
