The legendary Ollech & Wajs (OW) archive is brought back to life in the new OW M-52 'All Units', an automatic watch with roots in the military equipment supplied to US soldiers, pilots, sailors, and divers starting in the early 1960s. These timepieces were renowned not only for their extreme water resistance and indestructible durability but also for their reliability in any environment, from the theatre of war to demanding civilian construction sites.

Today, the OW M-Series expertly balances the robustness requirements of military personnel with the functional elegance demanded by the modern professional.

The M-52 AU is the embodiment of this philosophy. Born as an essential variant of the M-52B "Air Force" model launched for the B-52 Stratofortress’s 70th anniversary, the 'All Units' (AU) version merges the minimalism of a field watch, the practicality of a pilot's watch, and the water resistance of a diver's watch.

This versatility makes it suitable for "All Units" tactical operations, whether they are on land, at sea, or in the air.

Tribute to Vietnam: The name "All Units" is a direct tribute to a historical Ollech & Wajs model provided to American airborne troops during the Vietnam War. This historical link is reinforced by the reintroduction of the famous 12-hour world-time bezel and the characteristic red-numbered date wheel.

Universal Code: The indices on the dial combine applied dots and dashes, a subtle yet fascinating reference to the universal military language: Morse Code.

Inside the 39.5 mm 316L stainless steel case, with a brushed anti-glare finish, beats the mechanical heart of this instrument: a robust Swiss-made Soprod P024 automatic movement. It is assembled and regulated in three positions specifically for Ollech & Wajs, featuring a rotor engraved "OW Zurich 1956." It guarantees a power reserve of 38 hours and unwavering reliability.

With a screw-down crown and case back and an anti-reflective sapphire crystal, the M-52 AU achieves exceptional water resistance of 300 meters (30 ATM).

The Heritage bracelet and/or the brown leather strap can also be added.
