Perpetuating the aeronautical heritage of Bell & Ross and the visual signature of the “round within the square”, the BR‑X5 adds a new chapter to the history of the BR 05 collection.
MANUFACTURE CALIBRE [BR-CAL.323]
The House adds a horological dimension to the BR 05 collection by equipping its new BR‑X5 with a manufacture movement designed by the Swiss specialist Kenissi. In compliance with the specifications defined by Bell & Ross, several years of development were necessary to ensure the design, development and fine-tuning of the manufacture movement.
A MULTI-LAYER assembly
This multi-layer assembly is discreet from the front but comes into its own when looking at the BR‑X5 from the side. The hollowed-out architecture of the case middle is obvious, revealing a technical construction that optimises lightness without compromising on resistance.
±70-HOUR POWER RESERVE
Equipped with a personalised oscillating weight and a variable-inertia balance wheel, the BR-CAL.323 calibre beating at a frequency of 28,800 vibrations per hour (4 Hz) has a power reserve of approximately 70 hours. This so-called “weekend proof” capacity allows you to put your watch down on Friday evening and pick it up on Monday morning without having to wind it up.
CHRONOMETER CERTIFIED [COSC]
The mechanism is COSC certified, a first for Bell & Ross. The Swiss Official Chronometer Control Body grants it the name chronometer, a guarantee of great precision.
With this new BR-CAL.323 manufacture calibre, the brand values precision and reliability more than ever. Both the movement and the case are guaranteed for 5 years. Something that lovers of beautiful mechanical watches will appreciate.
