Luxembourg jewellers Schroeder has revealed its new limited edition "Black Broker" watch.

Schroeder Joailliers has extended its "Broker" collection with a blackened version of the Timepieces, limited to just three pieces.

The limited edition number is visible through the sapphire case back of the watch, engraved on the exclusively manufactured movement for Schroeder.  Iconic to the collection, the novelty simultaneously shows 7 different timezones on its dial. The steel button at 10 o'clock enables changing the main hands while the other timezones remain at their correct time.

Each of the three watches come with a different band: all black, black with white stitches or blue.
