Ollech & Wajs Astrochron - References, Prices and Owners' Reviews

The Ollech & Wajs Astrochron is an iconic watch that marked the history of watchmaking, notably for its use by NASA scientists in the 1960s. In 2023, the brand relaunched this legendary model, retaining its original spirit while integrating modern technical improvements.

Design and Technical Characteristics

The Astrochron's case is made of 316L stainless steel, known for its robustness and corrosion resistance. It measures 39.56mm in diameter, a size that strikes a balance between wrist presence and comfort. With a thickness of 14.5 mm, the watch maintains a sporty appearance without being too imposing. The brushed finish of the case gives it a decidedly toolwatch appearance, faithful to the aesthetic of professional watches.

The matte black dial is refined, emphasizing functionality. The indexes and hands are coated with Super-LumiNova®, guaranteeing optimal readability even in low light conditions. The second hand features a red tip, adding a touch of dynamism to the overall design.

One of the distinctive features of the Astrochron is its bi-directional rotating bezel, equipped with a 360-degree scale. This feature allows use as a compass, a valuable aid for outdoor adventurers and professionals. Additionally, the bezel incorporates a 20-minute scale, useful for dives or activities requiring precise time tracking.

Movement and Performance

The Astrochron is powered by the Valjoux 7753 automatic chronograph movement, renowned for its reliability and precision. This caliber offers a power reserve of 63 hours, ensuring comfortable autonomy for daily use. The choice of a hand-wound movement strengthens the link with period watches, while offering a tactile experience appreciated by purists.

One of the major improvements of this reissue is its water resistance increased to 500 meters (50 ATM), thus doubling the capacity of the original model. This performance is made possible thanks to a system of four seals at the level of the chronograph pushers, guaranteeing optimal protection against water. This feature makes the Astrochron a watch suitable for the most demanding environments, whether deep diving or terrestrial exploration.

Bracelet and Confort

The watch comes with a 20mm stainless steel bracelet, featuring a secure folding clasp. This robust bracelet ensures a comfortable and secure fit, suitable for sporting activities as well as everyday use. The build quality of the strap is in line with the rest of the watch, providing durability and a consistent aesthetic.

Conclusion

The Ollech & Wajs Astrochron is a watch that combines historical heritage and modern innovations. Its functional design, exceptional robustness and technical features make it an ideal choice for lovers of authentic tool watches. Whether for professional use or for the pleasure of a watch with a strong character, the Astrochron stands out as a reference in the world of watchmaking.
