Ollech & Wajs M52 AU (All Units)

We are pleased to introduce the new OW M-52 'All Units' (AU) – a wristwatch inspired by the classic Ollech & Wajs military watches used by US soldiers, pilots, sailors, and divers since the early 1960s. These watches are known for their high water resistance, exceptional robustness, and multifunctionality, which made them extremely popular not only in military contexts but also among civilian professionals working in challenging environments.

Today, Ollech & Wajs watches combine the demands of both military and civilian customers. This is particularly evident in the current M-series, known for its versatility and high functionality. The new OW M-52 AU is a simplified and clearly designed version of the M-52B 'Air Force' (AF), introduced earlier this year to celebrate the 70th anniversary of the B-52 Stratofortress. The M-52 AU combines the minimalist design of a classic field watch with the practical functionality of a pilot's watch and the water resistance of a diver's watch. This versatility makes the M-52 AU an ideal companion in any tactical situation, be it on land, at sea, or in the air – hence the name "All Units" (AU).

The dial design draws on the brand's military heritage, using a combination of dots and dashes for the indices, inspired by the universal military symbolism of Morse code. This design, along with the brushed finish of the 39.5 mm stainless steel case, which prevents reflections, gives the watch a clear and functional aesthetic. Inside the case, a Swiss automatic movement, the Soprod P024, operates, known for its robustness and reliability.

Another highlight of the M-52 AU is the 12-hour world time bezel, which rotates in both directions, and the striking red date window. These design elements are a tribute to the historical OW watches worn by US military personnel during the Vietnam War. The name "All Units" comes from a model specifically developed for airborne troops.

The watch comes with a military-inspired grey NATO strap made of highly durable nylon. This strap was handcrafted in Switzerland and features a brushed stainless steel buckle, engraved with the lettering 'OWZ 1956'. The price for the M-52 AU is 1,356 CHF, and it is possible to combine the watch with a brown Italian leather strap or an M-Heritage stainless steel mesh bracelet, both available as additional options. The leather strap costs 96 CHF, while the stainless steel bracelet is offered for 126 CHF.

Unlike previous models, the M-52 AU will not be released as a limited or numbered edition. This is because the watch is a variant of the existing M-52B AF and not a completely new model. To make the watch as accessible as possible, the M-52 AU will be moved directly into regular production. Shipping of the watch will begin at the end of October.

The technical specifications of the M-52 AU include a 39.5 mm brushed stainless steel case, which impresses with its robust construction and sapphire-coated glass, featuring an anti-reflective surface to maximize legibility. The watch is water-resistant up to 300 meters, making it ideal for use in extreme underwater environments. The movement, the Soprod P024, offers a power reserve of 38 hours and is regulated in three positions to ensure maximum precision. The hands and indices are coated with Super-LumiNova®, ensuring optimal readability even in low light conditions.
