The Breitling A73390 represents a significant achievement in professional diver's watches, embodying the brand's commitment to robust construction, unparalleled functionality, and sophisticated design. While not explicitly stated in the provided prompt, this model is definitively a variant within the Breitling Avenger Seawolf Chronograph family. This article will explore its key features, focusing on the innovative magnetic pushpieces that set it apart, and will also delve into related Breitling models to provide a broader context within the brand's extensive catalog.
The most striking feature of the A73390, and the core focus of this discussion, is its proprietary magnetic pushpieces. These aren't simply aesthetically pleasing additions; they are a crucial element of the watch's functionality, particularly in its intended environment – underwater. Traditional chronograph pushers rely on a precise, often delicate, mechanism to activate the timing functions. The risk of accidental activation, especially under pressure or with gloved hands, is significant. Water ingress through a compromised pusher seal is another major concern at significant depths. Breitling's solution, the magnetic pushpieces, elegantly circumvents these issues.
The magnetic pushers on the A73390 operate through a magnetic field, eliminating the need for a direct mechanical connection to the chronograph mechanism. This system offers several advantages:
* Improved Water Resistance: The absence of a direct mechanical connection dramatically reduces the risk of water ingress, enhancing the watch's overall water resistance rating. The A73390, like other Seawolf models, boasts exceptional water resistance, exceeding 3,000 meters (approximately 10,000 feet). This extreme depth rating solidifies its position as a true professional diving instrument.
* Enhanced Reliability Under Pressure: At significant depths, the pressure exerted on the watch case is immense. Traditional pushers could be compromised under such strain, leading to malfunction or even failure. The magnetic pushers, however, are less susceptible to these pressures, ensuring reliable operation even in the most extreme conditions.
* Improved Usability with Gloves: Divers often wear thick gloves for protection against cold and potential hazards. Operating traditional pushers with gloves can be cumbersome and imprecise. The magnetic pushers on the A73390 allow for more intuitive and reliable operation, even while wearing diving gloves.
* Reduced Risk of Accidental Activation: The magnetic system minimizes the risk of accidental activation, a critical safety feature when working underwater. Unintentional starting or stopping of the chronograph could lead to inaccurate timing and potentially hazardous situations.
The A73390, as a member of the Breitling Avenger Seawolf Chronograph family, shares design elements and robust construction with its siblings. The Avenger Seawolf line is renowned for its exceptional durability and resistance to the elements. These watches are purpose-built for demanding environments, whether it's deep-sea diving, extreme sports, or simply navigating challenging conditions. The robust case, typically constructed from stainless steel, provides excellent protection against impacts and scratches. The unidirectional rotating bezel, with its clear markings and easy grip, is essential for timing dives and other timed operations. The highly legible dial, with its luminous hands and markers, ensures readability even in low-light conditions. The sapphire crystal, known for its scratch resistance, further protects the dial and hands from damage.
