The name "AMADEE-20 Rolex" might initially cause confusion. There's no such thing as a Rolex model with that designation. The AMADEE-20 is, in fact, a significant milestone associated with the Fortis Official Cosmonauts Chronograph, a watch deeply intertwined with space exploration and boasting exceptional reliability. This article will delve into the intricacies of the Fortis AMADEE-20, exploring its design, the movement powering it (the Valjoux 7750-based UW-50), its history, and its significance within the world of horology and space exploration. We'll also address the common misconception linking it to Rolex and clarify its unique identity.
Understanding the AMADEE-20 Project and its Connection to Fortis
The AMADEE-20 mission wasn't a Rolex endeavor; it was a significant analog and digital space exploration project conducted in the Negev Desert of Israel. This ambitious simulation replicated the challenges of a lunar mission, preparing astronauts for future space travel. The project involved extensive testing of equipment and procedures under extreme conditions, mirroring the harsh environment of the Moon. Crucially, the Fortis Official Cosmonauts Chronograph played a vital role in this simulation. The watches worn by the astronauts during AMADEE-20 were rigorously tested, proving their durability and precision in the demanding simulated lunar landscape. This real-world testing solidified Fortis' reputation for building robust and reliable timepieces capable of withstanding extreme conditions.
The selection of Fortis wasn't arbitrary. The brand has a long and proud history of supplying watches to cosmonauts and astronauts. Their timepieces have been worn on numerous space missions, earning them a well-deserved reputation for reliability and accuracy in the unforgiving environment of space. The AMADEE-20 mission served to further reinforce this legacy and highlight the capabilities of their watches under extreme conditions.
The Heart of the Matter: The UW-50 Caliber
The Fortis Official Cosmonauts Chronograph AMADEE-20 is powered by the UW-50 caliber, a modified Valjoux 7750. This isn't a movement developed solely for AMADEE-20; the Valjoux 7750 is a highly respected and widely used automatic chronograph movement known for its robustness and reliability. However, Fortis has enhanced this base movement to create the UW-50, tailoring it for increased performance and durability.
The Valjoux 7750, the foundation of the UW-50, is an automatic, mechanical chronograph with a robust design. Its widespread use across numerous watch brands is a testament to its quality and reliability. The movement boasts a column-wheel mechanism for crisp chronograph operation, a feature often associated with higher-end movements. This contributes to the smooth and precise functionality of the chronograph functions: start, stop, and reset.
Fortis' modifications to the Valjoux 7750 resulting in the UW-50 likely involve enhancements to improve its resistance to shock and magnetic fields, crucial characteristics for a watch intended for use in extreme environments. These modifications might include reinforced components, improved lubrication, or specialized anti-magnetic shielding. While Fortis doesn't publicly detail every specific modification, the increased robustness is evident in the watch's performance during the AMADEE-20 mission.
