All about the OLLECH & WAJS OW P-104

The Return of the Selectron – The New OW P-104 Selectron

With great pride, Ollech & Wajs brings back the legendary Selectron designation into the collection – in the form of the new OW P-104 Selectron. This model incorporates design features of later Selectron watches, particularly those of the "Selectron Calculator" Ref. 004 released in 1969. This historical watch was delivered by Ollech & Wajs to General Electric Co. and specifically developed for their aerospace engineers and test pilots.

Precision meets tradition

In keeping with its historical predecessor, the new OW P-104 Selectron is also equipped with a bidirectional bezel that features logarithmic scales. This allows for numerous mathematical calculations to be performed with just one turn – faster than any so-called smartwatch. Additionally, it requires no battery and remains fully functional even underwater up to 300 meters. A truly intelligent solution!

The high-contrast dial, inspired by the minimalist instrumentation of a cockpit, guarantees optimal readability. The ivory-colored indices and the hands coated with luminous orange Super-LumiNova® ensure optimal visibility even in poor lighting conditions. The design is completed by a RAF regiment strap, a tribute to the close connection of Selectron watches to military aviation.

Swiss precision on the inside

The watch is powered by the Soprod Newton Precision P092, an outstanding automatic movement that has been specially modified according to the specifications of OW. This caliber is independently tested for its reliability and robustness at the renowned Laboratoire Dubois in Chaux-de-Fonds. It has been adjusted in five positions, features a distinctive OW-Zürich-1956 engraving on the nickel-plated movement plate, and is equipped with a specially designed rotor in the shape of the OW logo.

Limited Edition with COSC Certification

To celebrate the return of the Selectron, Ollech & Wajs is releasing an exclusive special edition of only 56 numbered pieces. Each model in this limited series is marked by an individual engraving on the crown (Number/56) and additionally features an official COSC certification from the Contrôle Officiel Suisse des Chronomètres (COSC). This confirms the highest accuracy and emphasizes the exceptional quality of this timepiece.

A watch for true connoisseurs

The OW P-104 Selectron is delivered with a regimental-style RAF nylon strap and is available for 1,656 CHF. Additionally, an OW S-Type "Beads of Rice" metal strap and a handcrafted black leather strap are available as accessories.

'While digital technologies are increasingly displacing traditional instruments, the OW P-104 Selectron proves that slide rule watches are far from obsolete. This model combines mechanical intelligence with timeless elegance and makes a powerful statement against the digital transformation.'
