The Breitling Montbrillant Olympus, a watch that evokes images of conquering heights and pushing boundaries, is less frequently discussed than some of Breitling's other iconic models like the Navitimer or Chronomat. However, understanding its movement is crucial to appreciating its place within the Breitling lineage and its unique contribution to the brand's horological history. While specific details about the *exact* movement used in every iteration of the Montbrillant Olympus are scarce in readily available public information, we can analyze the general characteristics and likely candidates based on the era of production and Breitling's movement history. This exploration will delve into the likely movements powering this robust and adventurous timepiece, comparing it to related models and examining the broader context of Breitling's mechanical calibers.
The Montbrillant Olympus, known for its imposing size and rugged design, typically housed a high-beat automatic movement. This choice reflects Breitling's commitment to precision and reliability, particularly important for a watch designed to withstand demanding conditions. While Breitling has utilized movements from various sources throughout its history, including ETA and its own in-house calibers, the most likely candidates for the Montbrillant Olympus fall within a few families.
Potential Movement Candidates:
Given the period of the Montbrillant Olympus's production, it's highly probable that the movement was based on a modified ETA caliber. Breitling, particularly in the periods before its significant investment in in-house movements, frequently sourced base calibers from ETA, modifying them to incorporate its own finishing, decorations, and specific functionalities. The high-beat frequency (typically 28,800 vibrations per hour or 4 Hz) suggests a caliber designed for enhanced precision and smooth operation.
Several ETA calibers could fit this profile:
* ETA 2892-A2: A highly regarded base caliber known for its reliability and accuracy, the ETA 2892-A2 is a frequent choice for modifications by numerous watch brands. Its relatively slim profile makes it suitable for incorporation into a range of watch cases, although it would likely have needed modifications to accommodate the Montbrillant Olympus's features and robustness. Breitling may have used a heavily modified version with enhanced shock resistance and potentially a different escapement system for improved durability.
* ETA 7750: A more robust and widely used automatic chronograph caliber, the ETA 7750 is another strong contender. While the Montbrillant Olympus is not primarily a chronograph, the ETA 7750's robust construction and modular design might have been attractive for Breitling, allowing them to adapt it and remove the chronograph functions to create a highly reliable three-hand movement.
* Breitling Caliber B01 (less likely for early models): While Breitling's in-house caliber B01 is a modern marvel, it's less likely to have been used in the early iterations of the Montbrillant Olympus. The B01's introduction is relatively recent in Breitling's history. Later versions of the Montbrillant Olympus *might* have incorporated a modified version of this caliber, but this is less probable given the overall design and price point of the watch.
Analyzing the Movement's Characteristics:
Irrespective of the specific ETA base caliber used, certain characteristics would be expected in the Montbrillant Olympus movement:
