The Ace x Frederique Constant Highlife Worldtimer Amsterdam is a limited edition of 100 pieces inspired by the city of Amsterdam, exclusively available at Ace Jewelers. The Ace x Frederique Constant Highlife Worldtimer Amsterdam departs from the opulent aesthetics of the regular model, opting instead for a sleek and utilitarian design. The sunburst finish with an embossed globe on the dial has been replaced with a matte black surface. Hints of red and white evoke the colors of the Amsterdam flag. The Ace x Frederique Constant Highlife Worldtimer Amsterdam comes with two straps: a stainless steel bracelet as well as an additional black rubber strap with red stitching.
