Ticking declaration of love to the golden era of motorsport

Launched by Ollech & Wajs in March 2023, the OW Rallychron is not just a ticking declaration of love to the glorious era of motorsport, in other words, the roar of powerful V8 and V12 engines and the intoxicating aroma of burnt rubber and high-octane petrol along the world’s most famous racetracks. With its unique chronograph design and incomparable look, it also captivates the hearts of pilot’s watch enthusiasts.

The 1960s and 70s were characterized in particular by the large number of different race tracks and the associated challenges for man and material. From the fast and flowing tracks such as Monza and Spa-Francorchamps to the narrow and winding roads of Monaco – each track regularly pushed drivers and crews to their limits and demanded maximum concentration and skill.

The design

Ollech & Waj’s many years of expertise in the manufacture of racing timepieces is reflected in the design of the OW Rallychron. The bezel of the chronograph features hypothetical “perfect lap times” of historic Grand Prix racing cars – including the Ferrari 312, Cooper Maserati and McLaren M4B – for eleven of the world’s most famous racetracks. The asphalt-grey dial provides the perfect contrast to the orange tips of the chronograph hand and the 30-minute hand, guaranteeing maximum legibility even in poor lighting conditions.

The chronograph is presented with a handmade black, perforated Italian leather strap in racing style. This is designed to be breathable and promises maximum comfort even on long journeys. Alternatively, there is the option of purchasing a stylish and extremely durable M-Heritage center mesh stainless steel bracelet with OW engraved pin buckles.

The case

A highlight, especially for all fans of pilot’s watches, is the classic chronograph case with its black and white checkered hands – an allusion to the well-known racing flag. In addition to minute and hour markers, the watch has a tachymeter scale. The fluted crown is complemented by the two traditional pushers, which are used to start, stop and reset the stopwatch function.

Ollech & Wajs has decades of expertise in precision timing instruments for motorsports, sports chronographs and racing timers.

The brushed 316L stainless steel case in the popular heritage style has a diameter of 39.5 millimetres and a height of 15.3 millimetres. It has a sapphire crystal with anti-shine treatment on the front and a screw-down case back. The OW Rallychron is water-resistant to a depth of 300 meters. The OW Rallychron is water-resistant to a depth of 300 meters. This corresponds to a water resistance of 30 bar and means that the watch can be worn while scuba diving without any problems.

The movement

Under the hood of the Rallychron is a highly modified and track-tested, individually engraved automatic Valjoux 7753 – a descendant of the historic Valjoux 72 movement that powered the best Swiss chronographs of the 1960s and 70s, including several OW models. The movement is equipped with a rotor machined by OW. It is regulated in five positions, adjusted and tested for flawless performance.
