This article delves into the intriguing combination found within certain Breitling watches, specifically the A44359 Blackbird model: the ETA 2892-A2 movement coupled with a Dubois Dépraz big date module. It's a configuration that, while seemingly straightforward, presents some nuances and raises questions for enthusiasts and watchmakers alike. The seemingly simple question – "What's inside my Breitling?" – can lead to a fascinating exploration of watchmaking history, movement modifications, and the intricacies of high-quality timepieces.
Part 1: Breitling Bentley Service, ETA 2892-A2, and the Dubois Dépraz Module
The Breitling Bentley series, known for its luxurious design and sophisticated complications, often utilizes variations of the ETA 2892-A2 movement. This base caliber, renowned for its reliability and accuracy, provides a solid foundation for Breitling's more complex creations. The ETA 2892-A2 is a slim, high-beat automatic movement with a date function. Its popularity stems from its versatility – it can be easily modified to incorporate various modules for added complications, such as chronographs, moon phases, and, as in the case of the Blackbird, big date displays.
The crucial element in our exploration is the Dubois Dépraz module. Dubois Dépraz is a highly respected independent manufacturer specializing in high-quality watch modules. They don't produce complete movements; instead, they create intricate add-ons that enhance existing movements with additional functions. In the Breitling Blackbird, and other models using this combination, the Dubois Dépraz module (often a 4500 series, but specific model numbers can vary slightly depending on the exact watch and year of production) is seamlessly integrated with the ETA 2892-A2. This module provides the big date complication, characterized by two separate windows displaying the tens and units digits of the date. The integration is often so seamless that the module appears to be an integral part of the movement itself.
Servicing a Breitling watch containing this ETA 2892-A2/Dubois Dépraz combination requires specialized knowledge and expertise. While the ETA 2892-A2 is relatively well-documented and readily serviced, the addition of the Dubois Dépraz module adds a layer of complexity. Finding a watchmaker familiar with both movements is crucial to ensure proper maintenance and repair. Improper handling can lead to damage to the delicate module, rendering the watch inoperable or requiring costly repairs. Therefore, seeking out a Breitling-authorized service center or a highly experienced independent watchmaker specializing in Swiss movements and modules is highly recommended.
