Here, for the first time, Moritz Grossmann’s pure watchmaking artistry stands out with a chic “used look” in a unique configuration: lacking a dial, with an irregularly oxidised steel case, the manufacture calibre 201.2 exhibiting a close-to-destructive surface finish, the sapphire-crystal glass visually cracked, the strap timeworn. The “Extreme-Dubai”, created in 2017, looks like a vintage timepiece from the 19th century even though it is brand new.

The 17 ½ pieces made for Ahmed Seddiqi & Sons stand for the friendship and affiliation between the two companies that in 2017 culminated with this shared project. The 18th “Extreme-Dubai” is split: the separate halves are on display in Glashütte and Dubai. Moritz Grossmann’s team looks forward to this debut at Dubai Watch Week, which under the auspices of Ahmed Seddiqi & Sons has evolved to become one of the most important horology shows in the Middle East.
