When the first ball is hit at the Australian Open in Melbourne, it is still dark.
The heat is already there, but the light has yet to come. The Australian Open begins at the edge of the day, where tennis becomes uncompromising. This is precisely where the Rallymaster IV has its origins.
The story of the Rallymaster IV, limited to 100 watches, begins with a love for a sport that gives even zero a feeling – love. Daniel Dreifuss loved tennis because it counts honestly and speaks emotionally. This love became part of the family, part of the Maurice de Mauriac brand. Today, Massimo, Leonard and Masha carry it on. In their lives and in their watches.
The Rallymaster IV pays homage to Melbourne, to the unforgiving hard court. The surface is fast, the sun merciless, every rally demands total focus. Time feels condensed here, concentrated, demanding. That's exactly how this watch ticks.
Like every Rallymaster, the IV was created through dialogue. Maurice de Mauriac and Carlton DeWoody bounced ideas off each other, one after the other. A real rally. Details were refined, colours questioned, lines clarified. Carlton found even the smallest things that could be improved. In the end, it wasn't one person who won, but the watch.
And then there is this moment that connects everything: Russell Crowe. During a visit to Zurich, he purchased a Rallymaster III. Later, he invited Massimo, Leonard and Masha to personally present him with the IV at his ranch. Tennis connects people. Time connects people. Sometimes this results in stories that are bigger than a watch.
The Rallymaster IV is for people who don't just watch tennis, they feel it. For everyone who knows that every rally is more than just a point. And in the end, it's not one person who wins, but the time spent together.
